PS08-32 Sequence, External Pilot, Internal Drain (PS08-32)
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 PS08-32 blocks flow from ➂ to ➁. On attainment of a pre-determined pressure at ➀, the valve shifts to open ➂ to ➁Back pressure at ➁ will have a direct (1:1) effect on the valve’s setting because the spring chamber is vented out ➁
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.
