PRESSURE CONTROLS

PS10-41 Sequence, N.O., External Pilot & Drain

DESCRIPTION

A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with

external pilot and spring chamber drain. It is designed to function as a pressure-

signalled, remote pilot-operated, two-way, normally open valve. A separate spring

chamber drain galley allows port

➂ or ➁ to be fully pressurized.

OPERATION

In neutral (unpiloted), the PS10-41 allows ﬂ ow between ➂ and ➁ bidirectionally.

The spring chamber is constantly vented at

➃.

On attainment of a pre-determined pressure at

➀, the cartridge shifts to close ➂ to ➁

bidirectionally.

FEATURES

• Adjustments cannot be backed out of the valve.

• Adjustments prohibit springs from going solid.

• Optional spring ranges to 151.7 bar (2200 psi).

• Hardened precision spool and cage for long life.

• Industry common cavity.
