Additional Information
Process Description
Brass is used as material to form the basic shape of the valve. The valve then goes through the process of upsetting (Forging), Stress-Relief Annealing, Shot Blasting, Machining, Secondary Annealing, Ultrasonic Cleaning, Assembly, Pressure Testing, Drying, Packaging, and Storage. With a final inspection, the valve will be packaged and sent out.
