Air-driven equipment operates efficientally & economically at specified controlled pressures. Airchamp high capacity, ruggedly designed Regulators for continuous service are essential to adjust & conserve compressed air accurately & precisely. Variation in supply pressure or air flow has no significant effect on regulated pressure. Available in three pipe sizes of 1/4 ,3/8 ,1/2 BSP. Maximum supply pressure 400 psig. Regulator is standardly supplied with reduced pressure range of 0-150 psig. Ranges of 0-60, 0-100&0-250 psig available on order. For the best performance choose the nearest reduced pressure range. Maximum temperature 75ºC. Body pressure die cast zinc alloy. Spring cage pressure die cast LM6. Renewable seat & Valve assembly brass. Screws, Valve spring & Strainer S. S. Regulating spring powder coated. Diaphragm, Disc & Seal gaskets buna / viton. Two full flow pressure gauge ports of 1/4 BSP, one sealed with brass plug.
