Wafer butterfly valve

The butterfly plate of the wafer butterfly valve is installed in the pipe diameter direction. This valve is fully open. The wafer butterfly valve is simple in structure, small in size and light in weight. Butterfly valves have two types of seals: elastic seals and metal seals. For rubber-sealed valves, the two-position two-way solenoid valve with the sealing ring can be inlaid on the valve body or attached around the butterfly plate.

Flange butterfly valve

The flanged butterfly valve is a vertical plate structure, the valve stem is an integral metal hard seal valve, the two-position five-way solenoid valve sealing ring is a composite structure of soft graphite plate and steel plate, and the valve body is installed with a butterfly plate sealing surface surfacing stainless steel. The sealing ring of the soft seal valve is made of NBR material and installed on the butterfly plate.

Lug butterfly valve.

The fourth is a welded butterfly valve.

Welded seam butterfly valve is a kind of non-sealed butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electric power, etc. The medium temperature is ≤300℃, and the nominal pressure is 0.1Mpa. It is used to connect, open or adjust the medium volume. .

The structure of butterfly valve is divided into:

Center sealed butterfly valve.

Single eccentric sealing butterfly valve.

Double eccentric sealing butterfly valve.

Triple eccentric sealing butterfly valve.

Install and maintain butterfly valves.

During installation, the disc should stop at the closed position.

The opening position should be determined according to the rotation angle of the butterfly plate.

For butterfly valves with bypass valves, the bypass valve should be opened before opening.

Install according to the manufacturer's installation instructions. When the butterfly valve is heavy, a firm base should be installed.
