Wafer Butterfly Valve Performance Advantages

55 views Source: VALTEC China Valve Manufacture CO.,LTD

Wafer butterfly valves are a common part of machinery used in industry, with a simple and compact structure and many different classifications for us to choose the right type.

Wafer Butterfly Valve

Wafer type butterfly valve performance advantages is that its disc is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully open. The wafer type butterfly valve is generally installed horizontally. The wafer type butterfly valve is composed of only a few parts and characterized by simple structure, small size and light weight. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple. In the meantime, the valve has good fluid control characteristics.

When the wafer butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small. The valve thus boasts better flow control characteristics.

Wafer butterfly valve has two sealing types: an resilient seal and a metal seal. For the former, the sealing ring can be mounted on the valve body or attached to the periphery of the disc.The wafer butterfly valves with metal seals generally have longer life than elastomeric seal valves, but it’s difficult for complete seal. Metal seals can accommodate higher operating temperatures, while resilient seals have temperature-limited defects.

Wafer butterfly valves are suitable for use in the pipelines of various corrosive and non-corrosive fluid media in the engineering systems of furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation, building water supply and drainage, etc., for regulating and intercepting the flow of media.
