PRESSURE CONTROLS
PS10-31 Sequence, Internal Pilot & Drain
DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with
internal pilot and spring chamber drain, designed to direct fl ow to a secondary circuit
once a pre-determined pressure level is attained in the primary circuit.
OPERATION
In its steady state, the PS10-31 blocks fl ow at ➀, while allowing fl ow to pass from
➁ to ➂.
On attainment of a pre-determined pressure at
➀, the cartridge shifts to open ➀ to ➁.
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.
