Valuable savings in size and weight are possible in equipment that uses the GS02 80 bi-directional solenoid valve from Sterling Hydraulics. Although this valve has a body less than 100mm high, it can handle flow rates as high as 58 litres/min, while offering minimal leakage in the closed position – features which make it an ideal choice for even the most demanding applications. Designed for use with mineral oils or synthetic oils with lubricating properties, GS02 80 solenoid valves provide normally closed operation, blocking flow in both directions when the solenoid is de-energised, and allowing bi-directional flow when it is energised.
Typical response time for opening and closing is just 40mS, and leakage in the closed state is less than 0.33ml/min. Standard GS02 80 valves are suitable for use at working pressures of up to 210 bar, and a high-pressure version, the GS02 81, is also available for use at up to 350 bar.
Both types incorporate thermal relief, which is factory-set to operate at 36 bar above their rated maximum working pressure. All valves in the Sterling Hydraulics GS02 80 range use waterproof, hermetically sealed coils that require no O ring, ensuring that they are suitable for use in the toughest industrial environments.
