Stainless steel pneumatic three partial hardness sealing butterfly valve D643H/W image

D643H/W stainless steel pneumatic triple eccentric butterfly valve with opening and closing without friction, corrosion resistance, high temperature resistant, etc, is mainly composed of high precision three partial hardness seal butterfly of pneumatic valve and single and double effect of pneumatic actuator, is a kind of rotary type high performance or cut butterfly pneumatic valve adjustment. Pneumatic three partial hardness sealing butterfly valve sealing principle of eccentric structure, no mechanical wear, has both excellent sealing function, achieve the pneumatic valve opening and closing butterfly plate with almost no friction phenomenon between pneumatic valve seat. Pneumatic valve rod torque through the butterfly plate pass directly to the sealing surface, thus put an end to the open ordinary common jump phenomena in the pneumatic valve.






D643H/W pneumatic triple eccentric belongs to hard seal butterfly valve with electric - Pneumatic valve positioner, solenoid pneumatic valve, air filtration pressure reducer, limit switch ( Pneumatic valve position to dispatch) , which can realize the process piping fluid proportion in regulation and two cut control, fluid flow, so as to achieve the parameters such as pressure, temperature, liquid level of automation control. Widely used in gas, turbid liquid, thick slurry or ash powder, suspended particles, such as medium.



d643h - 16 p three partial hardness stainless steel pneumatic sealing butterfly pneumatic valve:


D pneumatic valve type: said six drive form control pneumatic valve: electric control connection mode: flange connection 3 pneumatic valve structure: triple eccentric type

H sealing material: metal hard seal pressure pneumatic valve: 1. 6 mpa P = 16 kg pneumatic valve body material: stainless steel



the role of pneumatic actuators: double role: ventilation, ventilation, air failure to keep the current position

single acting normally closed type ( Gas) : ventilation, barely able to close, air supply failure automatically shut down, Spring return)

single acting normally open type ( Gas off) : ventilation, barely able to breathe, air supply failure automatically open ( Spring return)

optional accessories: reversing solenoid pneumatic valve, limit switch, air filtration pressure electrical and pneumatic valve positioner, hand wheel, a pneumatic valve
