Product Overview
Cartridge
Description
This is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position.
Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the external drain open and a minimum pilot pressure of 300 psi (20 bar).
Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
Any backpressure at the drain port is directly additive to the required pilot pressure for reliable operation.
Leakage rate between port 1 and port 2 is very low, typically less than 10 drops/min. at 5000 psi (0,7 cc/min at 350 bar).

Features
Valve will reseat when the pilot pressure falls below 145 psi (10 bar).
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids.
Exposure to petroleum based fluids, greases and lubricants will damage the seals.
These valves are hydraulically balanced between port 1 and port 2.
All ports will accept 5000 psi (350 bar).
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.
