Pneumatic tripple eccentric butterfly valve introduction
Pneumatic triple eccentric butterfly valve is composed of metal seated butterfly valve with flange type,wafer type or lug type and double or single acting pneumatic actuator,Pneumatic triple eccentric butterfly valve is used in petroleum, chemical industry, electric power, metallurgy, food, light textile, papermaking and other industries,Pneumatic triple eccentric butterfly valve can be installed in the temperature ≤425℃, medium for gas, air, steam, water, sea water, oil and other industrial pipe network for regulating flow and cutting off medium.The driving forms of  butterfly valve include manual, worm drive, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.Pneumatic triple eccentric butterfly valve structure adopts the principle of tripple eccentric structure, the valve seat adopts the hard and soft sealing compatible multi-level structure, and the machining is fine.This product is composed of valve body, butterfly plate, multi-level seat, stem, transmission mechanism and other main components.Therefore, Pneumatic triple eccentric butterfly valve is applied to pipelines of corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage.

Pneumatic tripple eccentric butterfly valve Product Features
Pneumatic triple eccentric butterfly valve is designed on the principle of three eccentricity, the space movement track of the sealing surface reaches the ideal, there is no friction between the sealing surface, there is no interference, and the sealing material is chosen properly, so that the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are guaranteed.Its main features are as follows:
1. Small opening torque, flexible, convenient and labor-saving.
2. Triple eccentric core structure makes the butterfly plate more and more tight, and its sealing performance is reliable, so that there is no leakage.
3, high pressure resistance, corrosion resistance, wear resistance, long use, etc.
