The soft sealing butterfly characteristics of pneumatic valve

the midline soft sealing butterfly pneumatic valve is a normal adjustment of pipeline preferable pneumatic valve, has the advantages of simple structure, small flow resistance coefficient and flow curve tending to straight line, not stranded sundry. And light weight, easy installation, the advantages of driving torque is small. This pneumatic valve can be used as cut off the medium, but also for regulating the flow of medium. Driving device according to user requirements, can use manual, electric, pneumatic, etc. Choose different material parts, with different material of the sealing ring, can adapt to different medium, the working condition, cost and performance to achieve the best effect. Soft seal butterfly pneumatic valve is suitable for the temperature ℃ or less or ℃ or less, nominal pressure or less. MPa water supply and drainage, sewage, food, heating, gas, shipping, water and electricity, metallurgy, energy systems, and textile industries, especially suitable for the double seal and pneumatic valve body easy to rust, to adjust flow and intercepting medium.
its main characteristic is:
, small and light, easy disassembling and maintenance, and can be installed in any position.
, simple and compact structure, small operation torque, ° slewing open quickly.
and flow curve tending to straight line regulation performance is good.
and be used between the butterfly plate and pneumatic valve rod structure without pin, overcome the possible leak point.
and butterfly plate adopts the cylindrical spherical shape, to improve the sealing performance and prolong the service life of the pneumatic valve, with pressure opening and closing more than ten thousand times remain zero leakage.
, seal can be replaced, and reliable sealing achieve two-way sealing.
and butterfly plate can spray coating according to user requirements, such as nylon or ptfe.
, the pneumatic valve can be designed as flange connection and the connection to the clamp.
, can choose manual, electric or pneumatic drive way.
