DE-MCS MANUAL POPPET VALVE, 2 WAY NORMALLY CLOSED, PULL TYPE, CORROSION RESISTANT
HYDRAULIC SYMBOL
PERFORMANCE VALVE SPECIFICATIONS
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, manual poppet valve, 2 way normally closed, pull type, corrosion resistant.
OPERATION
The DE-MCS blocks ow from (1) to (2) until an operator pulls the shaft outward. The bias spring allows for
backpressure at (2) before the valve will open (see option page for pressure).
Note: pressure at port (2) will directly act on the spool and spring. Port (2) is intended to be a tank port only.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
• Corrosion resistant.
• Optional bias springs for backpressure application exibility.
