Steel body and connections; bi-flow; maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F); Kv 10.2 m3/h (Cv 11.83 gal/min). Operated with a cap. Suits HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Straightway body places inlet and outlet in line.
