Pneumatic valve selection table < / div >

pneumatic valve selection table, tell you the model shows that a variety of pneumatic valves, pneumatic valves according to the different models you can understand the parameters, for example:
Z671X - pneumatic butterfly valve 16 C
Z = type code

6 = drive 7 = connection form

1 = structure form X = sealing surface material or lining material 16 = nominal pressure


C = pneumatic valve body materials pneumatic valve type code: butterfly = D pneumatic valve, pneumatic ball valve, pneumatic valve gate = = Q Z pneumatic valve, globe = = H J, check pneumatic valve, pneumatic valve decompression = = S Y, hydrophobic pneumatic valve, sewage, pneumatic valve = P = G, pneumatic diaphragm valve, pneumatic valve throttle = L

1。 About the nominal pressure: numerical with 10 times of the nominal menstruation ( Mpa） Said; Used in power plant industrial pneumatic valve, when the highest temperature over 425 ℃, with work pressure.
2。 About pneumatic valve body material: gray cast iron Z = ( Also can't ignore to write) , carbon steel, ductile iron = Q = 304 = P, stainless steel, stainless steel 316 = C R, 18 8 mo = RL, plastic = S stainless steel, copper and copper alloy, aluminum alloy = = T L, Cr13 stainless steel, malleable cast iron = = H K and so on. Warm prompt:
pneumatic valve CF3, CF8 = 304, CF3M = = 304 l, 316 l, CF8M = 316 material grades can be dimensioned directly on pneumatic valve body.
