a pneumatic triple eccentric butterfly Industrial Valves, stainless steel summary:

1, D643H - 16 p stainless steel pneumatic triple eccentric butterfly valve opening and closing with no friction, corrosion resistance, high temperature resistant, etc, is mainly composed of high precision three partial hardness sealing butterfly valve and double effect of pneumatic actuators, is a kind of rotary type high performance adjustment or cut off the butterfly Industrial Valves. Three partial hardness pneumatic sealing seal principle of eccentric structure of butterfly valve, no mechanical wear, has both excellent sealing function, do the valve opening and closing almost no friction phenomenon between disc and seat. Stem torque through the butterfly plate pass directly to the sealing surface, thus eliminating the opened the ordinary valves by common jump phenomena. D643H - 16 p pneumatic triple eccentric hard sealing butterfly valve with electric - Gas valve positioner, solenoid valve, air filtration pressure reducer, limit switch ( 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

2, D643H - medium 16 p three partial hardness stainless steel pneumatic sealing butterfly valve type description:

D - type: 6 - said butterfly Industrial Valves Driver: 4 - electric control Connection mode: flange connection 3 - Three eccentric valve structure:

H - 16 - sealing material: metal hard seal The valve pressure: 1. 6 mpa = P - 16 kg Body material: stainless steel

D643H - 16 p three partial hardness stainless steel pneumatic sealing butterfly valve actuator type:

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

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

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

4, optional accessories: the reversing solenoid valves, limit switches, air filtering pressure reducing valve, electrical locator, hand wheel, a valve
