Butterfly is a circular disc for opening and closing member and with the stem rotation to open, close and adjust a valve fluid channel. Butterfly valve plate is mounted on the pipe diameter direction. Cylindrical channel in the valve body, disc-shaped disc around the axis of rotation, rotation angle between 0 ° ~ 90 °, the rotation to 90 °, the valve is fully open state. Valve Co., Ltd. Shandong Everbright production of such types of valves wide range of applications, reliable, no leakage, leakage phenomenon, frequent switching is not stuck, rusted, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing, the best choice for food factory. Industry-specific characteristics of butterfly valves to high temperature, higher pressure range, the valve nominal diameter large, carbon steel valve body, valve type, valve plate seal with a metal ring in place of the rubber ring. Large temperature valve with welded steel manufacturing, valves, mainly for smoke duct and gas pipelines high temperature media. Valve Co., Ltd.
