The stainless steel REG-SA SS and REG-SB SS are angleway and straightway hand-operated regulating valves, which act as normal shut-off valves in closed position. REG-SA SS with the A cone is designed for expansion lines. REG-SB SS with a B cone is designed for regulating purposes e.g. liquid lines. The valves are designed to meet the strict quality requirements on refrigerating installations specified by the international classification societies and are carefully designed to present favourable flow conditions and accurate linear characteristics.
