DG-PSC SEQUENCE VALVE, 2 WAY NORMALLY CLOSED, EXTERNAL PILOT
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, 2 way normally closed sequence valve, external pilot.
OPERATION
The DG-PSC in neutral (unpiloted), blocks ow between (3) and (2). The spring chamber is constantly vented at
(1). On attainment of a predetermined pressure at (4), the cartridge shifts to allow ow from (3) to (2). Note that
the backpressure value at (1) must be added to the selected pressure setting to determine pilot pressure.
FEATURES
• Optional spring ranges to 1500 PSI (103 bar).
• Hardened parts for long life.
• Industry common cavity.
