Product Description

The butterfly plate of the butterfly valve is installed in the diameter of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, and the angle of rotation is between 0 degrees -90 degrees, and the valve is in full open state when it is rotated to 90. Butterfly valve is simple in structure, small in size and light in weight. It consists of only a few parts. And it can be opened and closed quickly only by rotating 90 degrees. The operation is simple and the valve has good fluid control characteristics. When the butterfly valve is in full opening position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop produced through the valve is very small, so it has a better flow control characteristic. Butterfly valve has two types of sealing: Bullet seal and metal seal. The elastic sealing valve can be inlaid on the valve body or attached to the periphery of the butterfly plate. Metal sealed valves are generally longer than elastomeric sealed valves, but it is difficult to completely seal them. Metal seal can adapt to higher working temperature, and the elastic seal has the defect of temperature limitation. If butterfly valve is used as flow control, the main choice is to choose the size and type of valve correctly. The structural principle of butterfly valve is especially suitable for making large caliber valves. Butterfly valves are widely used not only in petroleum, gas, chemical industry, water treatment and other general industries, but also in cooling water systems of thermal power stations. There are two kinds of butterfly valves commonly used for butterfly valves and butterfly valves. A double head bolt is used to connect the valve to the two pipe flanges, with flanged butterfly valves with flanges on the valve and connecting the flanges on the two ends of the valve to the pipe flanges.
