Butterfly valve

Butterfly valve is a valve that uses a circular butterfly plate as the opening and closing element and rotates with the valve stem to achieve the opening and closing action. It has the advantages of simple design structure, fast opening and closing, small pipeline area occupation, light weight, and small opening and closing torque. Zhejiang Shanliu Valve Technology produces various types of soft sealed butterfly valves, clamp butterfly valves, flange butterfly valves, triple eccentric butterfly valves, double eccentric butterfly valves, multi-level hard sealed butterfly valves, groove butterfly valves (clamp butterfly valves), welded butterfly valves, worm gear butterfly valves, electric butterfly valves, pneumatic butterfly valves, hydraulic butterfly valves, and PTFE sealed butterfly valves, which can be designed with functions of cutoff, adjustment, or both cutoff and adjustment according to different sealing requirements of the butterfly valves. The butterfly plate of butterfly valves has various structures, mainly including midline butterfly valves and eccentric butterfly valves. The main difference between the center line butterfly valve and the eccentric butterfly valve lies in the position of the valve stem. The fluid resistance of the center symmetrical plate is relatively small, but the sealing surface is prone to abrasion and leakage, so it is mostly used for flow regulation; The sealing performance of the inclined plate is good, but it is difficult to process; The sealing performance of the offset plate is also good, and it is easy to process and maintain, but the fluid resistance is relatively high.
