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.

1. BRIEF INTRODUCTION: 

The butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate

 the flow of medium. 

 

The valve can be actuated by operating lever, handle wheel electric actuator or pneumatic actuator. 

 

Widely used for potable water supply, waste water treatment, electric power plant, gas supply, 

warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light industries.
