Thread brass pressure reducing valve Feature
Thread brass pressure reducing valve is the direct action type diaphragm spring pressure reducing valve, which is designed and manufactured on the basis of absorbing the advantages of the same kind of foreign products.Thread brass pressure reducing valve is mainly composed of diaphragm, valve disc, adjusting spring and other parts.Thread brass pressure reducing valve is used the diaphragm to sense the downstream pressure change and to drive the disc.o as to realize the pressure reducing and pressure stabilizing function
Thread brass pressure reducing valve has appropriately increased the diaphragm area and improves the sensitivity.Pressure reduction is steady and sensitive.Thread brass pressure reducing valve is applicable to the branch pipe of high-rise apartment buildings and residential areas as well as the branch pipe of apartment and residence. -
