PS08-35 Sequence, External Pilot, Internal Drain (PS08-35)
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 PS08-35 allows flow from ➁ to ➂On attainment of a pre-determined pressure at ➀, the cartridge shifts to close ➁ to ➂Since the spring chamber is vented at ➂, back pressure at ➂ 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.
• Optional spring ranges to 165.5 bar (2400 psi).
• Hardened spool and cage for long life.
• Compact size.
