DE-MCL NORMALLY CLOSED MANUAL, PULL VALVE
VALVE SPECIFICATIONS
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, normally closed, manual pull valve.
OPERATION
The DE-MCL 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. The
cartridge offers smooth transition in response to load changes in common hydraulic circuits.
