Pneumatic Butterfly Valve Brief introduction:
Double eccentric end flanged resilient sealing butterfly valve is operated by the disc rotating form
0° to 90°, can be applied to cut off or regulate the flow of medium.
Vitreous enamel is available upon request.
The valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator.
Widely used for potable water supply and distribution, electric power plant, gas supply, warm-air system,
smelting plant, chemical industry.
Pneumatic Butterfly Valve Features:
⊙ Adjust tightness
Rubber sealing ring and disc can adjust tightness or softness of sealing with clamping ring, it insures
best performance of adjusting the compression of sealing.
⊙ Sealing reliable
Body and disc made of ductile iron which promote the impact resistance and pressure-bearing
capacity, sealing ring made of rubber and valve seat’s sealing surface is conical shaped, make the
sealing capacity more reliable.
⊙ Excellent corrosion protection
Inside electrostatic epoxy resin power coating or vitreous enamel(upon request), outside electrostatic
epoxy resin power coating.
⊙ Reliable health nature
Epoxy resin power is up to the health standard.
