What if the pneumatic midline butterfly valve does not return? This paper introduces a new technology of shear extrusion forming. The purpose and characteristics of large diameter forged steel pneumatic ball valve. By taking advantage of its advantages of energy saving and labor saving, the process parameters of shear extrusion forming for large forged steel valve body are obtained through experimental research on the forming process of valve body.
③ Solenoid valve: it is divided into single electric control solenoid valve and dual electric control solenoid valve.
Single electric solenoid valve: the valve is opened or closed when power is supplied, and closed or opened when power is cut off.
Dual electric control solenoid valve: when one coil is powered on, the valve opens, and when the other coil is powered on, the valve closes.
