MCVCV


Features Pilot pressure as low as 75 psi (5 bar) higher than the pressure at the vent can open the valve. Will accept pressure at port 4 (vent) but can not exceed 5000 psi (350 bar). Pilot-to-open check cartridges are locking valve, not motion control valve. For motion control applications, use counterbalance valve.

Features
Pilot pressure as low as 75 psi (5 bar) higher than the pressure at
the vent can open the valve.
Will accept pressure at port 4 (vent) but can not exceed 5000 psi
(350 bar).
Pilot-to-open check cartridges are locking valve, not motion control
valve. For motion control applications, use counterbalance valve.
Operation
This valve is a pilot to open check valve. It has a sealed pilot, a steel 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 pilot (port 3) 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 is referenced to the vent
(port 4).
