    Butterfly Valve Series

    Butterfly valve is a kind of valve to open, close or regulate the flow of medium by reciprocating the disc type opening and closing parts about 90°.

    Ball Valve Series

    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 Series

    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 Valve Series

    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 Series

    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 Series

    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. ​
