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.

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 and further information can be found at Hy-Pro Radio Remote

Lamma16 Farm Machinery Show

We are pleased to be supporting our distributor P & R Hydraulics at this year’s Lamma16 Show in Peterborough.  Taking place on 20th and 21st January 2016 at the East Of England Showground in Peterborough, Lamma16  is the top UK Farm Machinery and Equipment Show.  With over 900 stands and free parking and admittance, this event is expected to attract 40,000 farmers.

With P & R, we will be showcasing our sectional hydraulic control valves.  These competitively priced robust valves, manufactured in the UK and designed for harsh agricultural environments, come with a variety of controls (solenoid, manual and pnuematic) and accessories.  P & R are able to support applications in the field and we can provide expert technical advice and assistance with any application.

Come and visit us in Hall 4 on Stand 498.
