DAPS08-32 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, DAPS08-32 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 on 2 .

FEATURES

● Adjustments cannot be backed out of the valve.
● Adjustments prohibit springs from going solid.
● Hardened spool and cage for long life.
● Optional spring ranges to 165.5 bar（2400 psi）.
● Compact size.
