High-rise Building Design Pressure Reducing Valve Flange Connection 300PSI Pressure




The product for high-rise, high-rise building design, high-rise buildings to solve water, fire water systems, the requirements of flow, high sensitivity where the ideal product, its performance is more superior, completely replace the intermediate tank, saving the middle of the water construction the cost of boxes, and expand use of the building area.

This vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.

The valve is used to cover the surface of the gate of high quality rubber, the bottom of the valve design without grooves, so it has good elasticity, long life, no leakage, small flow resistance, prevent dirt accumulation caused by leakage or damage and other characteristics. The inner cavity of the valve body for spraying, use for a long time without corrosion and rust generated, effectively prevent secondary pollution, product without pollution. Widely used in food, medicine, to the field of water supply and drainage engineering, construction, fire and other for in liquid medium piping and equipment, as the dosing and opening.
