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.

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.

 

Hy-Pro’s Valves Specifically Designed for Pumps, Winches and Hose Reels

Here at Hy-Pro we design and manufacture valves specifically for Pumps, Winches and Hose Reels. The valves provide the products with the same basic element of a control system, for the on/off, in/out, and/or float functions together with a speed control.

We use these valves in a multitude of our products, including: The HRV, V4-40, V5-60 and V3-100 sectional control valves. The HRV was actually designed to meet one customers needs, but turned out to be a universal product for all our customers. Similarly, many of our Hose Reel products have specifications to meet an individual customer’s needs, but the majority of the product stays the same for all customers. A specialist feature for example would be a special metering needle which prevents the pump from being run too fast.

Hy-Pro has provided valves to between 800 and 1000 Hose Reels and Winches over the past year, supplying our products to a dozen of the largest OEM and many other smaller companies.

Many customers benefit from our HRV because it has the smallest and most used valve, which means the product is very compact. Also, Hy-Pro have the ability to “marinise” our valves for the harsh environments they are exposed in the marine and the road transportation industry.

Designing valves such as the ones for these products is one of our specialities here at Hy-Pro, customising a basic valve to meet a customer’s requirement is ultimately what we’re good at. However, one thing we had never had to do before was fitting one of these valves into an extremely tight space, it’s lucky that we are always excited by a challenge. We designed a special combined inlet cover with the speed control built in to make the assembly even more compact. This solved this dilemma and the customer was very happy with this result.

Ultimately this new and more compact valve has proven very popular, and is now manufactured for use by Hy-Pro customers all over the world.

Key Advantages of Using Hy-Pro’s Hydraulic Control Valves

Hy-Pro have been designing and manufacturing hydraulic control valves for fifty plus years after recognising the need for arobust, compact and economic solution for use across varied industry sectors…agriculture, forestry, marine, vehicle recovery trucks etc. Control valves form and essential part of a fluid power hydraulic system.

An hydraulic system is a method of transmitting power by pushing hydraulic fluid, generally mineral oil, round a circuit. The complete system comprises of a prime mover to drive the pump generating the flow. This could be an electric motor, petrol or diesel engine, air motor or a hand pump. A tank, filters, pipework and control valves completer the circuit along with the actuators which convert the power into either rotary or linear motion.

The advantages of fluid power transmission are –

  • Power density – large amounts of power can be produced from comparatively small actuators.
  • Safety in hazardous environments – hydraulic systems have a no electric shock risk, minimum heat build-up and are pollution free.
  • Instant reversing – because hydraulic fluid is incompressible actuators respond instantly to input command
  • Simple, rugged, serviceable – most components can be stripped, repaired and rebuilt quickly and easily.
  • Long distance transmission – hydraulic hoses can go round tight corners and run long distances without affecting the control.
  • Efficient – a well-designed system can have an total efficiency of over 92%. We are very conscious of the importance of this and ensure our valve designs are as efficient as possible.

Safety Lever Lock For Hy-Pro Control Valves

As always, our designers are putting safety first and we are happy to announce our new safety lever lock for Hy-Pro control valves.

The new V5145 safety interlock solution is a locking device which requires the operator to release the lever from its captive neutral position in order to select a service.

Hydraulic power is inherently dangerous and in a confined space or a busy area the inadvertent movement of a lever could cause serious damage or injury.  The new safety lever lock is designed to prevent such an occurrence.

The mechanism is manufactured in stainless steel with zinc-plated components for maximum durability.  Currently the device is available for horizontal levers but please ask if you need a vertical solution.  Please request the safety lever lock as an option when ordering your valve and choose from a selection of coloured knobs.

If this has caused you concern about your current installations, worry no further, the device can easily be retro-fitted to existing Hy-Pro control valves.

See our range of hydraulic control valves on our website or download our valve catalogue.

Hose Reel Valves

We have become well known for our bespoke, custom built control valves but we also manufacture ranges of specially designed valves for specific applications. Our hose reel valves, used in everything from airport fuel tankers to liquid food bulk carriers are particularly popular.

Manufactured to the highest standards, these valves has been specifically designed to operate hose and cable reels. The feature pressure compensated, knob operated speed control with integral relief valve. This is linked to a lever operated spool valve with 4 positions. The desired speed is selected using the speed control knob, then the direction of rotation is selected using the spring centred lever. The lever can also be detented into a fourth position which allows the reel to ‘free wheel’ enabling the hose to be pulled off by hand. In the neutral position the reel is locked hydraulically.

These G3/8 compact valves offer excellent metering, smooth speed adjustment from stop to maximum, an adjustable piloted relief valve and four operating lever position options….all in one robust, economical valve.

British Hydraulic Valves And Autopilot Pumps In Demand!

Here at Hy-pro, we were concerned when the British nation voted to leave Europe.  We worried about years of instability, uncertainty and the imposition of tariffs.  Whilst these fears are not unwarranted, there is a silver lining in the shape of exchange rates for British manufacturers.

We design, manufacture, assemble and stock all our products here in South Devon, England.  This means that our products are now up to 10% cheaper than equivalent goods manufactured in the rest of the world.  Our presence in the UK has always been a benefit to our UK customers because we are close at hand to help technically.  The added price advantages are now the icing on the cake.

We are currently seeing increases in sales directly related to exchange rates both here and overseas.  Our UK OEM customers are likewise seeing the benefits of a low pound on their own order books.  Meanwhile, overseas OEMs can also take advantage of cost reductions in their supply chain by buying British.

The sensible exchange rate which now prevails will hopefully stimulate the emergence of more UK manufacturers in other sectors, creating British jobs and ensuring our independence in the World.

Please see our website for our hydraulic control valve and marine steering ranges.

New G3/4 Pilot Operated Relief Valve

Having listened to our customers, our new G3/4 Pilot Operated Relief Valve has been re-designed to incorporate a safer, leak free, easily adjustable mechanism.  An all new external adjuster and lock nut gives zero-leakage and prevents loss of components whilst adjusting.

The new RV has an adjustment range of 25 to 250 bar and there is
also an optional tamper evident cover.  The cartridge will be standard in our V3-100 spool valve range from late July 2016 and will also be incorporated into our range of G3/4 line mounted manifolds.  On a technical note, please be assured this cartridge is fully interchangeable with our previous relief valve cartridge.

It is available as a cartridge to fit a standard Hy-Pro cavity or in a range of single and twin cartridge manifolds. The twin cartridge, 4 ported manifold is commonly used to prevent shock loads in hydraulic motors and equal ended cylinders.

Custom Hydraulic Control Valve

When we heard from our shop floor that we needed two people to move a custom hydraulic control valve, we had to investigate.  The V4-40 G3/8 range being a relatively compact design, weight is not usually a problem on that particular assembly line.  Taking over 2 hours to assemble and test, another issue was the lack of colour choices for knobs!

This custom hydraulic control valve, bespoke for our distributor Doedijns in Holland, is a 13 section manual valve, strengthened in the middle with a special mid-mounting section to cope with the prospect of attaching nearly 30 pulsing hoses!  The valve weighs around 35 kg and is almost 2 ft (565 mm) long, requiring specially manufactured studs to hold it together.  All the slices feature spring detent location with stainless steel handles and black anodized lever housings for maximum environmental protection.  The valve is completed with a top ported relief valve end cover and outlet cover and painted for maximum protection.  We always mount larger valves on plywood boards for protection in transit and this was no exception!

Being modular, our custom hydraulic control valves can vary in size enormously, especially with the addition of intersections and electric control options. Weight is more often a problem with our largest V3-100 G3/4 slice valve range and luckily we do have the necessary lifting equipment!

Radio Remote Control – New From Hy-Pro

We are pleased to announce the launch of our new radio remote control system at this year’s Fluid Power & Systems Show.

The new radio remote system complements our established range of solenoid operated control valves.   The system is aimed at small to medium OEMs who need to match the technology of larger companies but do not have the necessary internal expertise to source what they require.

The system comprises a paired base unit and handset, which will control 20 solenoids or 10 valve sections at a range of up to 45m.  Machinery can, therefore, be controlled from within the driver’s cab or from a safe distance.

The handset has a built-in rechargeable battery giving a run time of 10 hours and has a membrane keypad with LED indicators which can be customised for the OEM.  Our customers can choose their own symbols and corporate logo.

We can supply the base unit pre-wired to our customer’s specific requirements and it has auxiliary inputs which may be used for speed or position sensors, or interlock switches.

Our new radio remote control, whilst designed with our own range of Hy-Pro valves in mind, can also be configured for other manufacturers’ valves.

OEMs looking for a remote control solution for their machinery should visit the stand (AF324) at the NEC between 12th to 14th April 2016 for a demonstration and a chat with the experienced technical sales team.  Alternatively, contact Hy-Pro on 01626 863634 and ask for Alan Wilson or James Roberts.  The full range of Hy-Pro control valves can be found at www.hypro.co.uk and further information can be found at Hy-Pro Radio Remote
