Four-way valve handles higher flows

The GS04 57 four way valve is a high flow version of Sterling Hydraulics' highly successful G04 57 valve.

This year sees the introduction of a new addition to Sterling Hydraulics' leading range of solenoid valves.

The GS04 57 four way valve is a high flow version of Sterling Hydraulics' highly successful G04 57 valve.

Applications Manager Tony Raikes explains: "These four way valves are designed to operate double acting cylinders, bidirectional motors and other applications where you need to reverse the flow through an operating component".

The GS04 57 is a three position four way tandem centre spool valve with two solenoids.

When both solenoids are de-energised both operating valve ports are closed, and the flow from the valve's pressure inlet port is directed to the tank via the valve's outlet port, effectively bypassing the operating component.

With the top solenoid energised, operating port A is connected to the pressure inlet port and operating port B to the outlet port.

With the bottom solenoid energised operating port B is connected to the pressure inlet port and operating port A to the outlet port, reversing the flow through the operating component.

"The original GO4 57 has a flow capacity of up to 26 litre/min at pressure rating of 210bar", says Raikes.

"But discussion with our customers determined that this needed to be increased in line with their future development requirements".

"The new GS04 57 can handle flows up to 42 litre/min and operating pressures up to 350bar".

Like all Sterling Hydraulics' valves, the GS04 57 is available as 10-4 common cavity compliant or to customers' specifications, and can be supplied in anodised aluminium for operating pressures up to 210bar or in zinc plated steel for higher pressures.

All GS04 57 valves are manufactured and assembled at Sterling Hydraulics' factory, and receive 100% testing prior to despatch.
