200X Pressure Reducing Valves for Stable Downstream Pressure Regulation
PN1.0/PN1.6/PN2.5MPa, ANSI 125/150LB, sizes 3/4″ to 24″ (DN20~DN600mm), available in cast iron, ductile iron, carbon steel, stainless steel, brass, and bronze — accurate, stable, long service life.
Overview
200X pressure reducing valve is one type of automatic control valve to regulate and control pipe pressure through the fluids self-energy. 200X pressure reducing valve is applicable to living water supply, firefighting water supply and industrial water supply system. It can adjust the main valve outlet pressure without change because of affecting the inlet pressure or inlet flow change, but will keep on the set one safely and reliably. The valve can also adjust the set pressure to achieve the purpose of reducing the pressure. 200X diaphragm type pressure reducing valve has accurate pressure reducing, stable, safe and reliable performance, convenient installation & adjustment and long service life. Flowspec Luokai can manufacture the 200X pressure reducing valve applicable to be mounted on the pipeline with sizes ≤ DN600.
