Butterfly valves can be divided into pneumatic butterfly valves, electric butterfly valves, manual butterfly valves, wafer butterfly valves, and so on.
Wafer butterfly valves are a kind of valves that use circular butterfly plates as opening and closing parts and rotate with the stem to open, close and adjust the fluid passage.
The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc butterfly plate rotates around the axis, and the rotation angle is between 0 ~90. When the rotation angle is between 0 ~90, the valve is fully open. Wafer butterfly valve, also known as flip valve, is a simple structure control valve, but also can be used for low-pressure pipeline medium switch control. Wafer butterfly valve is a kind of valve whose closure (disc or butterfly plate) is a disc and rotates around the valve axis to open and close. It is mainly used for cutting and throttling in the pipeline. The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating. The wafer butterfly valve is usually less than 90 degrees open and closed. The butterfly valve and the butterfly rod have no self-locking ability. In order to locate the butterfly plate, worm gear reducer should be installed on the valve stem. The use of worm gear reducer can not only make the butterfly plate have self-locking ability, make the butterfly plate stop at any position, but also improve the operation performance of the valve. Industrial butterfly valves are characterized by high temperature resistance, high pressure range, large nominal diameter, carbon steel body and metal ring instead of rubber ring. In addition, ZECO Valve is the main manufacturer of wafer butterfly valves.
Wafer butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type and lever type according to its structure.
According to the sealing form, it can be divided into two types: the more sealed type and the harder sealed type. Soft seal type is usually rubber ring seal, and the hard seal type is usually metal ring seal. According to the connection type, it can be divided into flange connection and clamp connection. According to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic and electric.
ZECO Valve is one of the leading manufacturers of wafer butterfly valves in China. Welcome to inquire!
