Product Detail


Quick Overview


Max Pressure: 5000 PSI (345 bar)
Max Flow Rate: 10 gpm (38 l/min)

Pressure selection from either of two sources to a system can be made by actuating this HS3W cartridge valve with a pilot valve.

The HS3W valve is available for two-way pilot operation (spring returned) or four-way pilot operation. Electric, pneumatic, or manual operated valves can be connected to pilot ports. Normal spool position (from spring force or port 5 pressure) connects port 2 to port 3. Pressure at port 1 (port 5 drained) shifts the plunger to connect port 4 to port 3. In the case of four-way or double two-way piloted valves. If equal pressure are applied to ports 1 and 5 at the same time, the larger area on the port 5 end of the spool will tend to move the spool to its normal position. In the case of single piloted valve, port 5 must be connected to drain.

Valve is constructed of steel parts, all operating parts are hardened and cartridge is designed for easy service or field repair.
