Bi-direction valves save size and weight

Valuable savings in size and weight are possible in equipment which uses the GS02 80 bi-directional solenoid valve from Sterling Hydraulics.

Valuable savings in size and weight are possible in equipment which uses the GS02 80 bi-directional solenoid valve from Sterling Hydraulics.

Although this compact high-performance valve has a body less than 100mm high, it can handle flow rates as high as 58litres/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 210bar, and a high-pressure version, the GS02 81, is also available for use at up to 350bar.

Both types incorporate thermal relief, which is factory-set to operate at 36bar above their rated maximum working pressure.

All valves in the Sterling Hydraulics GS02 80 range use waterproof, hermetically sealed coils which require no O-ring, ensuring that they are suitable for use in the toughest industrial environments.

In addition, the coils can be physically reversed with no effect on performance, which simplifies installation, and allows users a choice of positions for the coil connections.

To maximise their versatility, GS02 80 bi-directional solenoid valves can be supplied with manual override facilities, either for local operation, or for remote operation via a cable.

They are also offered with a wide choice of AC and DC coil operating voltages, with the option of integral diodes on DC coils, and can be supplied with all standard types of connection.
