2-way, pilot-to-shift directional valve with drain to port 4 - normally open
Cavity: T-21A | Capacity:
Technical specifications
The normally-open, direct-acting 2-way directional cartridge with external drain is a pilot unloading valve used to sense pressure in one circuit to switch or unload a valve in a different circuit. When pressure at port 1 exceeds the setting of the valve, the spool shifts to block port 2 from port 3.
- The pilot area (port 1) and the spring chamber drain (port 4) are positively sealed.
- There is spool leakage between the work ports (ports 2 and 3)of less than 20 drops/min (1,4 cc/min).
- The valve is designed to not modulate and is the equivalent of a hydraulic pressure switch.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
