Electric metal seated butterfly valve introduction

Electric metal seated butterfly valve adopts triple eccentric structure, frictionless transmission between the sealing surface, with abrasion resistance, good mechanical performance, high temperature resistance, high pressure resistance and long service life.According to the connection mode,Electric metal seated butterfly valve can be divided into electric hard sealing flange butterfly valve and electric hard sealing sandwiched butterfly valve, Electric metal seated butterfly valve can be used for different industrial pipelines, as well as places with corrosive media.The electric sealind adopt metal hard seal butterfly valve or other hard material made and become, such as: carbon steel, stainless steel, stainless steel and hard alloy, etc, can be widely used in chemical industry, environmental protection treatment of 550 ° C or less, gas, oil, steam, water, and corrosive medium, etc to adjust flow or truncate the medium in the pipeline.

Electric metal seated butterfly valve working principle

The electric hard seal butterfly valve is composed of an electric actuator and a metal seal butterfly valve. The valve is opened or closed by the power drive of the electric actuator. The valve stem drives the disc to rotate back and forth within the range of 0-90 degrees.It can also be assembled according to the working conditions of intelli gent multi-rotary electric actuators or intelligent regulating actuators can realize unlimited automatic switch of butterfly valve butterfly plate and arbitrary adjustment of butterfly valve butterfly plate opening size, so as to control the temperature, flow, pressure, liquid level and other parameters * control.Under high pressure temperature and high pressure can maintain good operation, and more wear resistance, mechanical good, long service life, but the sealing performance is relatively poor compared to the soft seal butterfly valve.
