The complicated electric valve market has brought some troubles to many consumers, not to mention the uneven quality, the price difference is too much, even the model representation method has to come up with a variety of things, so the consumers of different lines are only in The entry of the model is hard to come by. In fact, all walks of life have their own default representations for the model representation of their own industry. Today we will talk about the model of the electric butterfly valve:
1preparation code: D means butterfly valve;
2 transmission form code: manual (omitted), 3 means turbine drive, 6 means pneumatic drive, 7 means hydraulic, 9 means electric;
3 connection code: 4 flange type, 6 welding, 7 pairs of clip type;
4 structural form code: 1 means center line type, 2 means double eccentricity, 3 means triple eccentricity, 4 means eccentricity, 5 means single eccentricity;
5 sealing material code: H stainless steel, X rubber, F polytetrafluoroethylene, FX composite rubber, M Monel alloy, Y hard alloy, W valve body direct processing;
6 pressure level code: 10=PN1.0Mpa, 16=PN1.6, 25=PN2.5, 40=PN4.0, PN is the code of domestic pressure, MPA is the unit of pressure; Class150LB=1.6mpa, 300LB=2.5 -4.0mpa, Class is the American standard American code, LB is the American standard pound unit.
7 shell material code: C cast steel, P stainless steel 304, R stainless steel 316, AL special alloy steel, Z cast iron, Q ductile iron, N nylon.
