Product Description

Original SUN DRAX-LAN Cartridge Valve Hydraulic Valve
 

The normally-closed, 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 connect port 2 to 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.
