Danfoss SCA-X 100 angleway stop/check valve, 100 mm (4 in) butt weld ASME B 36.10M Schedule 40, steel, 52 bar (code 148B6004)

Danfoss SCA-X 100 angleway stop/check valve for industrial refrigeration, code 148B6004. Combines manual shut-off and non-return (check) function in one steel body with butt weld connections to ASME B 36.10M Schedule 40, nominal size 100 mm (4 in). When open it acts as a stop valve; when the spindle is back-seated it works as a check valve, preventing reverse flow. Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). Flow coefficient Kv 196 m3/h (Cv 226.6 gal/min). Part of the Danfoss SVL Flexline programme; for R717 (ammonia), R744 (CO2) and fluorinated refrigerants.
