A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with internal pilot and spring chamber drain.
In its steady state, the PS50-36 blocks flow from ➀ to ➁, with the spring chamber drained at ➂On attainment of a predetermined pressure at ➀, the cartridge shifts to open ➀ to ➁Note that back-pressure on ➂ adds to the spring setting value.
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Spring range to 331 bar (4800 psi).
• Hardened spool and cage for long life.
• Industry common cavity.
