Advantages And Disadvantages Of Butterfly Valves
Oct 17, 2018

The characteristics of the industrial special butterfly valve can withstand high temperature, the applicable pressure range is also high, the valve has a large nominal diameter, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of the rubber ring. Large high temperature butterfly valve is made of steel plate welding, mainly used for high temperature medium smoke duct and gas pipeline

The advantages of the butterfly valve: easy and quick opening and closing, labor saving, small fluid resistance, and can be operated frequently. The structure is simple, small in size and light in weight. The mud can be transported and the liquid accumulated at the mouth of the pipe is minimal. A good seal can be achieved at low pressure. The adjustment performance is good.

Disadvantages of the butterfly valve: the use pressure and operating temperature range is small. Poor sealing.

Butterfly valve installation and maintenance: When installed, the valve flap should be stopped in the closed position. The open position should be determined by the angle of rotation of the disc. For butterfly valves with bypass valves, the bypass valve should be opened before opening. It should be installed according to the manufacturer's installation instructions. A heavy butterfly valve should be provided with a solid foundation.
