Shanghai Kangquan Valve Co., Ltd.

Double eccentric end-flanged resilient sealing butterfly valve is operated by the disc rotating form 0^o to 90^o, 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..

Professional design
When initiating the rotary opening movement the disc is off-seated after only a few degree of opening movement and there is very little wear and tear between seat ring and disc.
Combine fastness
Stainless steel seat ring is rolled into the valve body by applying special rolling technology when DN<1200 ultrasonic="" spray="" applies="" seal="" of="" valve="" body="" when="" dn="">1400.
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 seats 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.
