PS10-41 Sequence, N.O., External Pilot & Drain (PS10-41)
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 open valve. A separate spring chamber drain galley allows port ➂ or ➁ to be fully pressurized.
Product Operation
In neutral (unpiloted), the PS10-41 allows flow between ➂ and ➁ bidirectionally.The spring chamber is constantly vented at ➃On attainment of a pre-determined pressure at ➀, the cartridge shifts to close ➂ to ➁ bidirectionally.
Product Features
• 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 cavity.
