FLOW CONTROLS

CHECK VALVES

MAGNI-CHEK

Applications

Henry Technologies’

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 non-

corrosive to copper, brass, steel, and aluminum.

Magni-Chek Valves are used in discharge lines to

Technical Specifications

Maximum working pressure = 650 to 800 PSI (45 Bar to 55 Bar)

See table below

Allowable operating temperature = -20°F to +250°F (-29°C to +121°C)

Magni-chek Valves are USR and CNR recognized by Underwriters

Laboratories, Inc.

Valves 1-3/8 ODS and larger are CE marked in accordance with PED.

Materials of Construction

The valve body is made from solid copper. The seat is made from brass.

The retainer is made from aluminum. The flapper and screen are made from

stainless steel.
