PRESSURE CONTROLS
PS10-35 Sequence, External Pilot, Internal Drain
DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with
external pilot and internal spring chamber drain.
OPERATION
In its steady state, the PS10-35 allows fl ow from ➁ to ➂.
On attainment of a pre-determined pressure at
➀, the cartridge shifts to close ➁ to ➂.
Since the spring chamber is vented at
➂, back pressure at ➂ will directly (1:1) affect
the valve’s setting.
FEATURES
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Hardened spool and cage for long life.
• Compact size.
