Ball valve, the opening and closing parts (ball) driven by the valve stem, and around the ball valve axis for rotary motion of the valve. 

Gate valve is an opening and closing member of the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be used for regulation and throttling. 

Globe valves, also known as cut-off valves, are forced-sealed valves, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. 

Check valve refers to the opening and closing parts for the round valve and rely on their own weight and media pressure to produce action to block the medium backflow of a valve. 

Regulating valve refers to the adjustment of medium flow, pressure, temperature, liquid level and other process parameters in the field of industrial automation process control, according to the control signal in the automation system, automatically adjust the opening of the valve, so as to realize the adjustment of medium flow, pressure, temperature and liquid level. ​
