soft seal pneumatic wafer type butterfly valve
Pneumatic soft seal butterfly valve is combined with pneumatic actuators and central line of butterfly valves.
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.
Product features:
1) Seal valve seat water line design, the valve palate seal surface graphic design, completely
avoid the recruitment phenomenon for the valve long time no open
2) The disc in holes in the up and down, adopt the ball type friction surface design, torque more
small, sealing better
3) Gentle slope type seat small torque with long service life
4) Flange clamp holes connection apply to many standard
