As the pneumatic valve model establishment method

as pneumatic valve model establishment method:
as pneumatic valve additional code: W bellows B, D, low temperature, heat preservation;
) By the pneumatic valve category code: J said stop pneumatic valve;
) As pneumatic valve drive mode: manual without code, bevel gear, pneumatic, electric;
) As pneumatic valve connection mode: flange, welding;
) As pneumatic valve structure forms: cut-through, Z pass-through, tee, Angle type, Y type once-through, balance straight-through type, balance Angle, needle type;
) By the pneumatic valve sealing material: F fluorine rubber nylon plastic, stainless steel, H, N Y hard alloy, monel alloy, m. W pneumatic valve directly processing;
) As nominal pressure pneumatic valve: shows the pressure. The meaning of mpa 16 kilograms, PN. - mpa、INLB- LB、- K；
) By the pneumatic valve pneumatic valve body material: A titanium alloy, carbon steel, chrome molybdenum steel, stainless steel, P I C R stainless steel;
such as: WJH - Pneumatic valve, corrugated pipe cut-off C W bellows, J as pneumatic valve, flange, cut-through, H 16 kilograms, C carbon steel stainless steel, pressure.
