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.
