PS10 -34 Sequence, Internal Pilot & Drain

DESCRIPTIONA screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve withinternal pilot and spring chamber drain.

OPERATIONIn its steady state, the PS10-34 blocks flow from to , with the spring chamberdrained at .

On attainment of a predetermined pressure at , the cartridge shifts to open to .

Note that back-pressure on adds to the spring setting value.

FEATURES Adjustments cannot be backed out of the valve.

Adjustments prohibit springs from going solid.

Optional spring ranges to 117.2 bar (1700 psi).

Hardened spool and cage for long life.

Industry common cavity.
