Features These valves have positive seals between port 2 and the pilot area Because these valves are unbalanced, operation is pressure dependent. Opening and closing of the poppet are functions of the force balances on three areas: Port 1 = 100%, Port 2 = 80%, and the Pilot Area = 180%. All ports will accept 5000 psi (350 bar)

Features

These valves have positive seals between port 2 and the pilot area

Because these valves are unbalanced, operation is pressure

dependent. Opening and closing of the poppet are functions of the

force balances on three areas: Port 1 = 100%, Port 2 = 80%, and

the Pilot Area = 180%.

All ports will accept 5000 psi (350 bar)

Operation

These unbalanced, vent-to-open logic valves are 2-way switching elements

that are spring-biased closed and have port 1 as a pilot source. With port 3

blocked, the valve will remain in the closed position in the 1 to 2 direction and

will function as a check valve from 2 to 1. With port 3 vented, the valve will

open provided there is sufficient pressure to overcome the spring force. The

force generated at port 3, plus the spring force, must be greater than the sum

of the forces acting at port 1 and port 2 for the valve to remain closed.

NOTE: The pilot area (port 3) is 1.8 times the area at port 1 and 2.25 times the

area at port 2.
