These flanged, heavy-duty, piston-type check valves control the flow of refrigerant. Valves open wide for flow in the direction of the arrow on the valve body. Valves close tight when flow reversals occur. The piston design minimizes pulsations. Valves open when inlet pressure exceeds outlet pressure (1 psid [.07 bar] minimum), thereby lifting the piston/seat assembly and allowing flow through the valve. When inlet pressure and outlet pressure are equalized, the weight of the piston/seat assembly causes the valve to close. If outlet pressure exceeds inlet pressure, the outlet pressure acting on top of the piston/seat also helps seat the valve closed.
