Product Introduction
Screw valve is a common pneumatic control valve, mainly used for switching control of gases, liquids and other fluids. Its main feature is to realize the opening and closing of the valve through the pressure signal, simple operation, rapid response, suitable for the application of automatic control system.
The main structure of the valve includes a ball, a seat, a valve stem, a threaded connection part and an air source interface. The ball is the core component, usually round, and when the air pressure is applied to the ball, the ball will rotate, thus changing its position relative to the seat, enabling it to open or close. The opening of the valve can be precisely controlled by adjusting the pressure or changing the rotation Angle of the ball.
The threaded connection section allows the valve to be easily…
