Part Number
148B5937 · HS 8481.30

Danfoss CHV-X 80 angleway check (non-return) valve for the SVL Flexline industrial-refrigeration range, code 148B5937. Butt-weld connections to ASME B36.10M Schedule 40 in low-temperature steel. Angleway body (inlet and outlet at 90 degrees); Kv 103 m3/h (Cv 129 gal/min); minimum opening differential pressure 0.04 bar (0.62 psi); maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). CHV-X check valves prevent reverse flow in refrigeration lines and open on very low differential pressure. Flow direction is marked by an embossed one-way arrow. Suits HCFC, HFC, R717 (ammonia) and R744 (CO2) systems.
