PRESSURE CONTROLS
PS10-34 Sequence, Internal Pilot & Drain
DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with
internal pilot and spring chamber drain.
OPERATION
In its steady state, the PS10-34 blocks fl ow from ➀ to ➁, with the spring chamber
drained at
➂.
On attainment of a predetermined pressure at
➀, the cartridge shifts to open ➀ to ➁.
Note that back-pressure on
➂ 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.
