Danfoss SCA-X 25 angleway stop/check valve, 25 mm (1 in) butt weld EN 10220, steel, 52 bar (code 148B5408)

Danfoss SCA-X 25 combined stop and check valve for the SVL Flexline industrial-refrigeration range, code 148B5408. The SCA-X provides a manual stop function and a built-in non-return (check) function in one body, used in pump and compressor discharge lines to permit free flow in one direction while preventing reverse flow, and to isolate when closed. The angleway body has butt weld connections to EN 10220 in 25 mm (1 in). Flow coefficient Kv 24 m3/h (Cv 27.7 gal/min). Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). Cold-resistant steel housing for HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Built on the SVL Flexline modular platform; the check module shares parts with the CHV-X check valve.
