PS08-30 Valve

PS08-30 Valve symbol


A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve
with internal pilot and spring chamber drain, designed to direct oil to a secondary
circuit once a pre-determined pressure level is attained in the primary circuit.

In its steady state, the PS08-30 blocks flow at 1, while allowing flow to pass from 2 to 3.
On attainment of a pre-determined pressure at 1, the cartridge shifts to open 1 to 2.

• 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, industry-common size.
