Apollo 58B Double Regulating Valve

Double Regulating Valve

Apollo 58B Regulating Valve are intended for the isolation and regulation of sections of pipe work and equipment in HVAC applications and general commercial applications. Valve pressure drop can be read through the valves integrated 1/4” measurement ports, and flow calculated from the flow coefficient associated with the numerical setting on the side of the handle. These valves have non-rising stems that help reduce the amount of space needed. The integrated fixed orifice offers greater accuracy than that of a variable orifice.
