The characteristics of the pneumatic valve handle a butterfly

the handle control pneumatic valve is composed of a few parts, only so simple structure, small volume, light weight, and the operation is simple, convenient and flexible, rapid opening and closing in a rotating °. Butterfly pneumatic valve in the fully open position, the butterfly plate thickness is medium flows through the only pneumatic valve body resistance, and so by the pneumatic valve pressure drop is small, so has good flow control characteristics.
the handle control the purpose of the pneumatic valve is very broad, often used in gas pipeline in the sulphuric acid industry and sulphuric acid system of burning sulfur, transformation, dry absorption section. Handle butterfly pneumatic valve is sulphuric acid plant with the brand of choice for pneumatic valve, pneumatic valve handle adjustment sealing performance is good, work light, corrosion resistance, high temperature resistant, safe and reliable use, so get the use of a large number of users. Pneumatic valve handle adjustment but also used in chemical, petrochemical, metallurgy, medicine, food and other industries SO, steam, air, gas, ammonia, CO gas, oil, water, salt water, alkali liquor, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media on the pipeline as the adjusting and intercepting device is used.
the handle adjustment structure of the pneumatic valve features:
(1) because the handle control pneumatic valve of three eccentric to the unique design makes no surface friction transmission, so as to prolong the service life of the pneumatic valve.
(2) generated by the torque of the elastic seal.
3. Handle control pneumatic valve wedge design make the pneumatic valve has closed more and more tightly automatic sealing function of seal face between with compensatory, zero leakage.
(4) handle control pneumatic valve body small, light weight, simple operation, easy to install.
(5) according to user requirements, pneumatic and electric device, meet the needs of the remote control and programmed control.
6 replacement parts material can be applied to all kinds of medium, and the lining can be anti-corrosion.
7) pneumatic valve handle butterfly continuous diversification of structure have to clip, flange and butt weld ends.
