Sanitary Butterfly Valve Product Features

Sanitary stainless steel butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It is mainly used for cutting and saving on pipelines. The opening and closing part of the stainless steel butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulation. The full opening and closing of the sanitary stainless steel butterfly valve is usually less than 90°. The stainless steel butterfly valve and butterfly stem themselves have no self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the valve stem. The use of a worm gear reducer can not only make the butterfly plate have self-locking ability, so that the butterfly plate can be restrained in any position, but also improve the operating performance of the valve. The characteristics of industrial stainless steel butterfly valves are high temperature resistance, high force range, large nominal diameter of the valve, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high-temperature sanitary stainless steel butterfly valves are made of steel plate welding and are mainly used for smoke and air ducts and gas pipelines of high-temperature media.

The advantages of sanitary stainless steel butterfly valves are as follows:

1. It is convenient and quick to open and close, labor-saving, with low fluid resistance, and can be operated frequently.

2. It has a simple structure, small size and light weight.

3. It can transport mud and accumulate liquid at the pipe mouth.

4. Under low pressure, it can achieve excellent sealing.
