Proportional & On/Off Pilot Control of Clutches, Brakes & Directional Control Valves

Comatrol—a global leader in the design, manufacture and sale of engineered hydraulic cartridge valves—introduces 09 Series Cartridge Valves for proportional and on/off pilot control of clutches, brakes and directional control valves.  The series includes two on/off solenoid valves and a proportional pressure reducing valve.  The valves are especially designed for pilot applications requiring minimal pressure losses in the system.

The 09 Series is a hybrid product that combines a 10 size cavity with an 08 size tube/coil, thus optimizing performance for pilot control applications.  The large 10 size cavity provides high flow capability with low pressure drop, while the 08 size tube/coil provides a smaller package size and lower power consumption of the coil.

Rocco Marella, Comatrol Account Manager (Italy), shares, “This product line was engineered from our many years of experience in agriculture and construction equipment transmission control, with over 500,000 already in the field at key customers.  We worked closely with our customers to create world class pilot control valves that help reduce power losses, while minimizing the installation space in the vehicle.  Rocco continues, “We are continuously challenged by our customers to increase the efficiency of hydraulic components, and the 09 Series provides our customers with an optimal solution.”

The two on/off solenoid valves offer customers the choice of 2-position, 3-way (SV09-23-02) and 2 position, 4-way (SV09-24-01) schematics. Both of these popular schematics can operate to pilot pressures of 100 bar (1450 psi), higher than many pilot valves in the industry.  The flow rate for both are over 20 LPM (5.3 GPM), exceeding that of even standard 10 size solenoid valves, which are around 15 LPM (4 GPM).

When the application needs proportional pilot control, the PPR09-POD provides precise electro-proportional control of the clutch or directional valve.  It is a proportional pressure reducing / relieving valve that is pilot operated and normally open to drain. This design means that there is no actuator movement with zero current, which is ideal for these pilot control applications.  The valve comes with standard reduced pressure settings of 20 bar (290 psi) and 25 bar (360 psi), with market-leading flow capability exceeding 25 LPM (7.0 GPM).

For all 3 valves, use the optional inlet screen to protect the system from large particles.  Select the robust coil for those extreme environmental conditions – voltage extremes, high temperature, shock & vibration, chemicals, and/or water ingression.

Comatrol’s 09 Series coils are designed for incorporation on machine control architecture that utilizes Sauer‐Danfoss PLUS+1™ hardware.  Adding 09 Series valves to your application using PLUS+1 GUIDE software is as easy as drag-and-drop.
