PS10-33 Sequence, External Pilot, Internal Drain (PS10-33)
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with external pilot and internal spring chamber drain.
Product Operation
In its steady state, the PS10-33 blocks flow from ➂ to ➁On attainment of a pre-determined pressure at ➀, the cartridge shifts to open ➂ to ➁Since the spring chamber is vented at ➁, back pressure at ➁ will directly (1:1) affect the valve’s setting.
Product Features
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Spring range to 240 bar (3500 psi).
• Hardened spool and cage for long life.
• Industry common cavity.
