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

• 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.
