Dwyer Instruments 2004VA32-231-QS | 1-1/2" control valve | Cv of 32.10 | Bronze body | USP set at 125 psig (8.6 bar) | USP adjustable range 104-137 psig (7.2-9.5 bar)
Anderson, W.E. Single seated, top or cage guided globe valves are known as Hi-FlowTM control valves, and they are among the most versatile and likely the simplest to manufacture control valves now in use. Due to its higher flow capacity than most traditional valves of the same size, the Hi-FlowTM control valve can be used in applications that call for a smaller valve. In addition to its large flow capacity, the Hi-FlowTM control valve ensures accurate control by maintaining a wide rangeability of 50:1. Robustly built from premium materials, heavy-duty Hi-FlowTM control valves undergo precision machining and performance testing to provide years of trouble-free operation. PTFE V-rings and wipers are used in standard packing to reduce friction at high working pressures without leaking.
