The main production process copper pneumatic valves

. Product design
. Mould making
. Pneumatic valve casting, forging,
( ） Foundry casting: the earliest production of pneumatic valve field model, because the casting type does not have enough pressure lead to the production of the pneumatic valve is prone to sand holes cause leakage induced a series of problems.
( ） Hot forging press forging: after forging forming of pneumatic valve body will not have trachoma, external appearance more beautiful.
