HYDRAULIC SYMBOL
PERFORMANCE VALVE SPECIFICATIONS
DESCRIPTION
8 size, 3/4-16 thread, “Power” series, manual poppet, 2 way normally closed, pull type valve.
OPERATION
The PB-MCA blocks ow from (1) to (2) until an operator pulls the shaft outward. The bias spring (see option page
for pressure) allows for backpressure at (2) before the valve will open.
Note: pressure at port (2) will act directly on the poppet and spring. Port (2) is intended to be a tank port only.

• Hardened parts for long life.
• Industry common cavity.
• Optional bias springs for backpressure application exibility.
