PS10-40 Valve

PS10-40 Valve symbol

A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve
with external pilot and spring chamber drain. It is designed to function as a pressure
signalled, remote pilot-operated, two-way, normally closed valve. A separate spring
chamber drain galley allows port 3 or 2 to be fully pressurized.

In neutral (unpiloted) the PS10-40 blocks flow between 3 and 2 bidirectionally. The spring
chamber is constantly vented at 4. On attainment of a pre-determined pressure at 1, the
cartridge shifts to open 3 to 2 bidirectionally.

• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Optional spring ranges to 151.7 bar (2200 psi).
• Hardened precision spool and cage for long life.
• Industry-common size.
