Two Way Distributing Valve Rotary Discharge Valve

Wafer Type Butterfly Valves

The disc of the wafer style butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°, which can play the role of flow regulation. When the butterfly plate rotates to 90°, the valve reaches the maximum opening. The wafer style butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. And it can open and close quickly by rotating 90°. The operation is simple, and the lug and wafer type butterfly valve has good fluid control characteristics.

The Features of Wafer Type Butterfly Valves

1. The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the lug and wafer type butterfly valve.

2. An elastic seal is produced by torque.

3. The ingenious wedge-shaped design enables the valve to have an automatic sealing function, with compensation and zero leakage between the sealing surfaces.

4. Small size, light weight, light operation and easy installation.

5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

6. The material of the replacement parts can be applied to various media, and the lining can be anti-corrosion (lining F46, GXPP, PO, etc.).

7. Continuous structure diversification: wafer, flange, butt welding.

Applications of Wafer Type Butterfly Valves

Lug and wafer type butterfly valve is used for gas pipelines in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the series and connection valves of the electric demister, the inlet and outlet of the S02 main blower, the adjustment of the converter, the inlet and outlet of the preheater, etc. and the use of cut-off gas.

Wafer style butterfly valve is used for sulfur incineration, conversion and dry suction in the sulfuric acid system. It is the preferred brand of valves for sulfuric acid plants. It is considered by the majority of users as flexible, safe and reliable butterfly valves with good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, which have been widely used.

Lug and wafer type butterfly valve is also widely used in: SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid in chemical, petrochemical, smelting, pharmaceutical, food and other industries. It is used as a regulating and shut-off device on pipelines such as medium.
