National standard flange nodular cast iron butterfly D341X - pneumatic valve 16Q

DX flange rubber pneumatic valve the pneumatic butterfly 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. Hong feng butterfly pneumatic valve parts, choose different materials with different materials of the sealing ring, can adapt to different medium, the working condition, cost and performance to achieve the best effect. Is a normal adjustment of pipeline preferable pneumatic valve, suitable for 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, 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.
DX flange rubber butterfly pneumatic valve working principle: the rotary center of the disc ( The pneumatic valve stem is located in the center of the centerline of the body and disc sealing surface on the cross section, the butterfly plate rotation Angle can complete opening and closing. Pneumatic seat is synthetic rubber. Think hong feng pneumatic valve closing butterfly plate of cylindrical pneumatic seat sealing surface extrusion synthetic rubber, pneumatic seat produce elastic deformation and elastic force as seal pressure to ensure that the butterfly pneumatic valve seal.
DX butterfly pneumatic valve flange rubber product features:
u can choose manual, electric or pneumatic drive way. Flow curve tending to straight line being good regulation performance.
mixer seal can be replaced, and reliable sealing achieve two-way sealing.
has small and light, easy disassembling and maintenance, and can be installed in any position.
s simple and compact structure, small operation torque, ° slewing open quickly.
- butterfly plate can spray coating according to user requirements, such as nylon or ptfe.
bring about butterfly plate and pneumatic valve stem without pin structure is used to connect, to overcome the possible leak point.
delta 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.
