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.

Increasing pressure with increasing current.

• Analog proportional relief valve regulates pressure proportionally to the input solenoid current.
• Direct acting poppet design.
• One piece cartridge housing ensures internal concentricity.
• Coil: Waterproof, hermetically sealed, required no O-Rings; Symetrical coil can be reversed without affecting performance.

Operation
This valve is a direct acting proportional style relief valve. With zero input current, relief pressure is at its minimum value. Increasing current to the coil, proportionally raises the relief pressure form port 1 to port 2.
