Pneumatic Butterfly Valves are very useful to control highly inflammable liquids like petro-chemicals, Oil, and Gas. It is operated by Pneumatic which allows fast functionality and safe from fire and electric short circuits. So it is an electricity efficient operated valve with the lowest cost.
Product advantages:
1.Heavy body,the thickness of valve body meets the requirements of GB26640 to ensure bearing strength.2.epoxy coating, spray thickness up to 250um.Strong adhesion.
3.import EPDM rubber material. 50 percent rubber content, Stable and small torque, zero leakage after open and close more than 10000 times .
4.Wider rubber seat,wider contact surface with flange.better sealing performance.
5.Each valve will be wasted by ultrasonic cleaner before packing, Remove dirt and granularities from valve body. Prevent the valve itself from coordinating the media in pipes.
