PS08-32 Valve

SYMBOL:
PS08-32 Valve symbol

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 PS08-32 blocks flow from 3 to 2. On attainment of a
pre-determined pressure at 1, the valve shifts to open 3 to 2. Back pressure
at 2 will have a direct (1:1) effect on the valve's setting because the spring
chamber is vented out 2.

FEATURES
• 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.
