Pilot Ratio: 3:1

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).

The Sun Hydraulics CVCV-XCN + MAV/S combination is a cartridge valve assembly consisting of a pilot-operated check valve (CVCV) in a line-mounted body (MAV/S).
Assembly Components:
Cartridge: CVCV-XCN – This is a pilot-to-open check valve.
–> Pilot: Pilot to open.
–> Seal: Nitrile (N).
–> Adjustment: Standard screw adjustment (X), though for a check valve, this usually indicates no external adjustment, or a standard, non-adjustable model.
Body: MAV/S – This is a line-mounted assembly.
–> Material: The /S modifier indicates the body is made of SG Iron (ductile iron), which is required for pressures exceeding 210 bar (3000 psi).
–> Application: It is commonly used as a check valve with a reverse free-flow and a gauge port.

This valve is a pilot to open check valve. It has a non-sealed pilot, a steel seat, and is non-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 at port 3 to open the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes pilot pressure.

This valve is a pilot to open check valve. It has a non-sealed pilot, a steel seat, and is non-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 at port 3 to open the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes pilot pressure.
