Our New 5 Position Valve Section!

The team at Hy-Pro are proud to announce the release of our new multi-function hydraulic valve.

What is it? 

The exclusive 5 position valve section has been designed to use in a range of winch applications or as a multi-function valve. 

It can be used in operations requiring momentary, constant control, or both.  

When used in unison with quick release couplings, 1 single spool section alone can be used to control various pieces of equipment. 

What Materials is it Made From? 

The valve’s body is made from cast iron, a virtually indestructible metal, perfect for mechanical operations.  

Cast iron also resists abrasion and indentation, being a great durable material to withstand heavy loads and great deal of pressure. 

The product’s seals are made from a combination of nitrile and Viton rubber. 

Nitrile is an oil-resistant material, as well as being water-resistant, hydraulic fluid and other mechanical substances. 

Viton rubber is great at preventing abrasion and harsh weather conditions. It’s also repellent of UV exposure, oxidation and various chemicals. 

Product Specification 

In terms of pressure, the valve can withstand a maximum of 250 bar and a back pressure of 25 bar. 

It can function in temperatures over 65°C and at a minimum of -20°C. 

The component weighs a total of 2kg and has a section width of 38.1mm. 

Its rated flow is 60 I/min and spool leakage is 8cc/min.

With the dawn of September and increased demand from our customers, the last of our furloughed staff will return to work.  This is an exciting moment after a very uncertain time.  We do live in a changed world and we are maintaining social distancing across the site.  Some staff are still working from home but they are all contactable in the usual way.

Whilst quiet, we have taken the opportunity to improve our systems, our organisation and plan for a more automated and efficient factory.  We are about to launch a new shop floor data collection system, which will enable us to track components as they pass through machining and final assembly.  We are also talking to consultants about the introduction of robots into our machine shop in order to increase lights-out production for a planned doubling in production over the next 5 years.  Last but not least, we will be introducing a brand new website in the next couple of weeks.

The design and technical department have also been busy and we have introduced a new 5 position spool section and a 4 position regenerative spool section into our V5-60 and V4-40 ranges.  On the marine side, we have developed a brand new PR+05 pump for marine autopilot systems for smaller craft.  These are all available now – please contact sales on 01626 863634 or sales@hypro.co.uk

Please note that lead times are at least 5 days for small orders and at least four weeks for larger production orders.  Whilst we will try to help out in emergencies, it is important that our OEM customers plan for their production and place orders in good time.

In other news, we need to let everyone know that there have been changes in our Sales team.  Sadly Samuel has left Hy-Pro (we wish him every success) and Richard is now heading up another department and a replacement is being sought.

Please see our full range of products and more about us on www.hypro.co.uk


Wishing all of our customers a speedy recovery.

Hydraulic Pilot Operated Check Valve

Designed for use in applications requiring an actuator to be locked in position, Pilot Operated Check Valves allow free flow from the input port through the output port. Supplying a pilot pressure to the valve allows flow in the opposite direction.

Typically, there are two types of hydraulic pilot operated check valve. These are the line mounted type with integral or external oil pilot and the manifold type that can be mounted directly to a cylinder or a control valve. Most systems and users will find that these designs of valve work most effectively when in conjunction with a control valve, which allows the valve ports to vent to the tank once it has been centred.

If you would like more information on this and related products, our experienced sales team will be pleased to help. Please contact us on 01626 863634 or email sales@hypro.co.uk

British To the Core

With the uncertainties of Brexit and trade wars, there has been a pressing need for British self-sufficiency in engineering in the last couple of years.  Quality, supply problems and lack of local expertise have also been a problem in the past for smaller OEMs.  Recently, these problems have become even more of a threat with Coronavirus which is now threatening to cut supply chains across the globe.

Tim Wright Ltd, British manufacturers of post driving machinery since 1992, recognised the dangers of globalisation ten years ago.  Quality was an important issue for them as well as continuity of supply and they decided to source in the UK wherever possible.  “We even have our nuts and bolts made in Birmingham”, they proudly report.

Tim Wright, themselves manufacturing in Rocester, Staffordshire, produce a whole range of post drivers under the WRAG trademark.  Their range extends from small ones to fit 1.5-ton excavators to the self-propelled WRAGTRACK OPUS and bespoke machinery.

Mainly seen in the fencing, forestry and agricultural industries, WRAG post drivers are now also found in the construction, railway and highway sectors.  Their largest market is the UK and Europe, but they sell to other countries, including the USA and Australia.

The secret of their success is producing high-quality machinery.  This is due to a highly skilled workforce and close relationships with British suppliers, enabling them to have full control of their processes and components.  The hydraulic system is a key part of post driving machinery and British hydraulic control valve manufacturers are a rare breed.  However, they did find Hydraulic Projects Ltd who manufacture the Hy-Pro range of control valves in rural South Devon.  Hydraulic Projects, established in the 1960s by Dick Hammond (an engineer of the Tomorrow’s World and Raymond Baxter era) have been developing and manufacturing the well-known sectional valve for much of that time.  The V5-60, a 60-litre valve is now produced on the latest CNC lights-out machinery in the factory in Dawlish and is the valve of choice for small to medium OEMs requiring robust quality solutions.  The team at Hy-Pro have in-depth knowledge of their in-house designed valves and their applications.  In addition, like Tim Wright, the Hy-Pro valves are machined and assembled by a skilled workforce on site.

The WRAG machines use 8, 9 and 10 lever V5-60 spool valves controlling the “set up functions” of the machines, giving precise positioning at the user’s fingertips.  The machines can operate within a 180-degree arc and they boast that “no awkward corner is impossible”. The hammer function accelerates the weight, exploiting the high capacity tank galleries, offering very little resistance to the oil flow.  This allows the weight to fall quickly, which is important in a post driver.

Whilst there are foreign monoblock options, they are often unsuited to complex applications from a single oil supply.  In contrast, the V5-60 sectional valve can be assembled in any configuration.  The Hy-Pro valve is particularly suitable to the WRAG installation because of its oversize internal oil galleries, coupled with the extensive range of ancillary elements offered as standard.  The most important virtues of the Hy-Pro valve are that is readily available on short lead times and comes with direct support of the design and manufacturing team here in the UK.

Hy-Pro are Open for Business

We would like to assure all of our customers and suppliers that we are still open for business here in Devon. Due to the temporary closure of some of our customers and the need to maintain social distancing, we have reduced the number of people on site down to about 1/3. Everyone who can do so is working from home.

Our technical sales team are all at the end of a phone as usual, as are people in our accounts and purchasing departments.

We do maintain good levels of stock for most of our popular products but our machine shop is currently running at reduced capacity. This means that our usual stocks will fall. For this reason, I would ask that our regular OEM customers and distributors consider their requirements at least one month in advance. We are currently scheduling our machines for the second half of May.

Proportional Flow Divider – Information & Advantages

Flow dividers – are devices which split the flow from a pump into two streams for independently operating two branch circuits. Advantages of flow divider operation are: 

  1. Only one pump is required. This is a particular advantage in the saving of space, and reducing cost. 
  1. Each branch circuit is isolated from the other: changing loads on one branch will not affect the pressure or flow in the other branch. Flow dividers are only for hydraulic systems; they are not applicable to most industrial air systems. 

Spool-type dividers can be built to deliver proportional flows from two outlets, or to deliver a priority flow from one outlet with excess flow coming out the other outlet. Only the spool-type is manufactured by Hydraulic Projects. 

When Are They Used?

Two general methods are used for dividing a flow of oil. One method uses a sliding spool; the other method uses rotary construction, and operates similarly to two gear-type pumps with shafts coupled together. The two gear sections meter proportional amounts of oil to each outlet. 

They are used on agricultural and industrial machinery to control the speed of the bed chains or drums, and also in tracked vehicles to control the speed and direction of travel. 

How Are They Made?

The body is aluminium, and the rest of the components are either hardened or nitro-carburised steel. 

The action of spool-type and rotary-type dividers is quite different, and each requires a degree of technical knowledge to apply them properly and on suitable applications. 


The product is manufactured in the UK, for excellent service and support. When combined with our solenoid controlled directional valves, they provide an economical alternative to full proportional control.

Solenoid Diverter Valves

In order to control your hydraulic system to the level that is most efficient, you cannot afford to ignore the advantages offered by hydraulic diverter valves. This central point in a hydraulic system will drastically decrease the need for unnecessary additions, such as extra valves, hoses and fittings.

Hydraulic Diverter Valves

With this 6-way solenoid hydraulic diverter valve, you can control two separate double-acting circuits from the single directional control valve. This can be a great way to reduce the complexity of your hydraulic system, and shrink it into a much more convenient and manageable size, particularly for heavy-duty machinery and portable hydraulic systems.

You can control two double-acting cylinders or reversible hydraulic motors separately from a single valve.

For more information on any one of our hydraulic diverter valves, contact our friendly and specialised team.


Our Brushless Constant Running Pump

Hy-Pro has recently developed a ‘brushless constant running pump’ that is compatible with large yachts and other commercial craft.

The specialist pump offers a more reliable alternative, requiring less maintenance and offering increased performance. Read on to find out more information about why this pump could be much more beneficial compared to some of the other models out there.

What is a Brushless Constant Running Pump?

The brushless DC motor was designed by Hy-Pro specifically for marine autopilot applications, particularly in the large commercial boat market.

It is used for marine applications such as Trawlers and other commercial craft as well as some larger yachts, and is used to power the hydraulic steering system when the autopilot is in use.

A brushless motor means there is very little ongoing maintenance needed, as the pump is brushless the motor is controlled electronically. This gives us new options for performance moving forward.

The heavy vessels within ordinary hydraulic pumps require a lot of power to steer the vehicles. However, the new and innovative design of the Brushless Constant Running Pump goes against this rule. Instead of using a large DC motor, this pump runs continuously in one direction whilst a solenoid switches the hydraulic flow port and starboard – this saves the crew members having to manually steer the vessel.

For example, fishing boats can be at sea for many hours and the autopilot can be set to run a course or a pattern, this will allow the full crew to be on deck and working on other tasks.

How Does the Pump Work?

The hard-over time is set via the speed control and the steering action is achieved by switching a damped heavy duty double-acting solenoid valve.

The motor and precision gear pump is protected by a pre-set relief valve and check valves with toughened components, these positively lock the steering on course.

The pump has been developed for compatibility with both single and twin ram systems within the boat’s hydraulic steering. The specialist design is also suitable for unbalanced rams.

A ram, sometimes known as a steering cylinder is a critical part within the hydraulic steering system. Choosing the right ram is important to ensure the boat’s steering operates correctly and efficiently.

The brushless pump has also been designed to work alongside pressurised reservoir systems. This component holds the hydraulic fluid in a convenient part of the system and sustains any excess fluid needed.

What is the Pump Made?

Our pump has been integrated with flow output options and a compact construction. This aids in the pump’s durability and longer life span for functioning the steering of marine applications.

Our product has been made from aluminium and a large amount of copper, giving it good bearing properties and also a protective coating for harsh marine environments.

What are the Benefits?

The design consists of built-in overload protection and requires zero maintenance from the user.

In comparison to other models, the brushless motor has a much lower power consumption making it highly efficient. With 12V and 14V options available, this motor is an extremely heavy-duty alternative to others on the market.

This design could potentially replace the PC30 and PC45 in the future due to its convenience working alongside many other components and its futuristic design.

The integral speed control and relief valve also benefits its performance and contributes to a quieter operation.

This pump could be available as early as next year, so make sure you stay tuned for more updates on this pump.

If you’d like to find out more information about our brushless pump you can get in touch with us at Hy-Pro and we’d be happy to help!
