Wafer Butterfly Check Valve Color Customer Requied for Fire Fighting




Wafer butterfly check valve a save-energv product, is manufactured based on the foreign advanced technology and in accordance with relative international standards. This product is featured by excellentretaining perfomance, high safety and reliability and low flow resitance. it is suitable for systems in the industries of perochemical, food processing, medicine, textile, paper-making, water supply and drainage, metallurgy, energy and lightindustry etc used as a check valve in one way.

This butterfly 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 disc of the wafer type butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0°-90°, which can play the role of flow regulation. When the disc rotates to 90°, the valve reaches the maximum. Opening degree.
