Vented pilot-to-open check valve with external pilot port, standard pilot, stem
seal, and Delrin seat
SERIES 2 / CAPACITY: 120 L/min. / CAVITY: T-2A
This valve is a pilot to open check valve. It has a non-sealed pilot, a Delrin seat, and is vented. It allows free flow
from the valve (port 2) to the load (port 1) and blocks flow in the opposite direction. Pressure at the external pilot
port will open the valve from port 1 to port 2. Pilot pressure needed to open the valve is directly proportional to the
load pressure at port 1. The valve is insensitive to pressure at port 2 because the spring chamber references the
vent (port 3).
