Product Overview
Cartridge
Description
This is a normally closed, balanced poppet, switching element. When the vent port (port 4) is blocked, the poppet remains in the closed position. Venting port 4 shifts it to the open position, provided there is sufficient pressure at port 3.
Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
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).
Valve will reseat when the pilot pressure falls below 145 psi (10 bar).
