A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with external pilot and internal spring chamber drain. It is designed to function as a remote pilot-operated three-way valve.
In neutral (unpiloted), the PS10-43 allows flow between ➂ and ➁ bidirectionally, while blocking at ➃The spring chamber is constantly vented at ➃On attainment of a pre-determined pressure at ➀, the cartridge shifts to close ➂ to ➁, while opening ➂ to ➃. Note that back-pressure value at ➃ must be added to the selected pressure setting to determine pilot pressure.
• 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.
