Pneumatic valve and American standard gb pneumatic valve is the main difference

pneumatic valves are mainly American standard API and ASME standard, ASTM, ASTM material standard; According to the American standard design, manufacturing, production, testing of pneumatic valve is called the American standard pneumatic valve.

the control unit of the pneumatic valve is a fluid conveying system, a cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow, etc; Used for fluid flow control system of pneumatic valve, from the most simple of American standard cut-off pneumatic valve to the extremely complex control system used in all kinds of pneumatic valve, American standard its quite various varieties and specifications. Pneumatic valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow.

pneumatic valve American standard and national standard of pneumatic valve is the main difference between:
pneumatic valve nominal diameter of the unit is mm, gb, American standard pneumatic valve nominal diameter of the unit is in ( Inches.
, flange standard American standard and national standard is not the same.
length, structure is different.
and inspection requirements, American standard pneumatic valve inspection requirements than the elevation.
, national standard pneumatic valve pressure level unit is the MPa, American standard pneumatic valve pressure level unit is LB
