    Description

    Pnuematic butterfly valve introduction

    Pneumatic butterfly valve is combined with pneumatic actuators and central line of butterfly valves. The valve stem drive the valve corn rolling 90 in the body which can realize the full open or full close action. This product can according to the sealing performance into metal seal and soft seal with compact structure?small volume?reliable operation?good sealing?easy maintenance installation convenient and the adoptability is strong advantages. Can be widely used in petroleum?chemical industry?light industry?papermaking industrial?pharmaceutical?car automatic control system on a remote concentrated or local control.
