Our internal Application Technology department and field staff are happy to provide free advice on custom solutions.

     The main advantages, pneumatic butterfly valve has the advantages of simple structure, small volume and light weight, low cost, pneumatic valve of the notable features, installed in the upper passage, after two position five way electromagnetic valve control,convenient operation, but also adjust the flow media. 

      Fluid resistance small, medium and large caliber pneumatic butterfly valve fully open when the effective flow area is large, rapid opening and closing effort, dish plate rotate 90 angle to complete theopening and closing, on both sides of the shaft disc hand medium force approximately equal torque direction, the contrary, the smaller opening and closing torque, good sealing can be realized under low pressure, butterfly valve sealing material butadiene acrylonitrile rubber, fluorine rubber, edible rubber, PTFE lined the sealingperformance is good, the hard seal butterfly valve for the hard and soft laminated metal sheet has the advantages of heavy metal hard seal and elastic seal, no matter in low-temperature conditions both with excellent sealing performance.

     Working principle

     Pneumatic butterfly valve is a circular rotation with orange butterfly valve plate to open and close, to enable the action of pneumaticvalve main shut-off valve used to do, can be designed to have asection of the valve regulating or the function and regulation,butterfly valve used more and more in low pressure large caliber pipe.

    Butterfly simple structure, small volume, light weight, only by a few parts. But only can be rotated 90 ° rapid opening and closing,simple operation, while the electric valve has a good flow control characteristics. Butterfly valve in the fully open position, the disc thickness is only when the medium flows through the bodyresistance, thus generated by the valve pressure drop

    Very small, it has a good flow control characteristics. Butterfly valvewith elastic metal seal and the seal two kinds of sealed type. Elastic sealing valves, seals can be mounted on the body or attached to the disc periphery.

     If asked to use as a flow control valve, the main choice is the right size and type of valve. Butterfly valve structure principle is particularly suitable for production of large diameter valves.Butterfly not only widely used in oil, gas, chemical, general industrial water treatment, but also used in thermal power plant cooling water system.
