Sterling Hydraulics provide one of the most comprehensive and technically advanced cartridge valve ranges in the World. They design and manufacture pressure and flow control valve cartridges, solenoid valves, including proportional valves.
As well as having a comprehensive product range, they have the design expertise and manufacturing capabilities to produce custom designed manifolds that are tailor made to suit customer's requirements.

Proportional Pressure Regulating
2 Position, 3 Way Side Cylinder Port.
Minimal Hysteresis.
One piece cartridge housing ensures internal concentricity.
Waterproof coil hermetically sealed, requires no O-Rings.
Symmetrical coil can be reversed without affecting performance.
Nonmagnetic spool and housing assembly.

Operation
Analogue proportional pressure regulating valve, regulates pressure at port 2 relative to the solenoid current. Regulated pressure is virtually independent of input pressure. The solenoid force is balanced against the regulated pressure that provides feedback to maintain the spool's position. Typical applications are the control of transmission cluthces or cylinders.
