CHECK VALVES
MAGNI-CHEK
The function of a Check Valve is to allow fluid flow in one direction
only.
Applications
Henry Technologies’ Magni-Chek Valves are used in discharge lines to
prevent flow from the Condenser to the Compressor during the “off” cycle, or
to prevent flow from an operating Compressor to one that is idle. They are
also used in liquid lines to prevent reverse flow through the unused
expansion device on heat pump systems, or to prevent backup into the low
pressure liquid line of a recirculating system during a defrost period. Henry
Technologies’ Magni-Chek Valves are suitable for use with HFC and HCFC
refrigerants and their associated oils, as well as other industrial fluids noncorrosive to copper, brass, steel, and aluminum.
