    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. ​

Check Valve Series

H44H

Swing check valve

Swing check valve is widely used in chemical, petrochemical, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmaceutical, electronic industry and other relatively clean media fields.
Vertical, horizontal, recommended not tilt installation

H41H

Lift type check valve

Lift type check valve is widely used in chemical, petrochemical, petroleum, paper, mining, electric power, liquefied gas, food, pharmaceutical, electronic industry and other media relatively clean fields.
It is recommended THAT THE valve be installed horizontally with the bonnet facing up vertically

H76(H/X/Y)

Sandwich double disc check valve

The sandwich check valve is mainly composed of valve body, disc, stem and spring, and is connected by clamp. Due to the short disc closing stroke and spring loading, the water hammer phenomenon can be significantly reduced. Mainly used in municipal, industrial and high-rise building water supply, drainage pipe network, because its structural length is shorter than the general check valve, so easy to install

H72(Y/W)

Sandwich check valve

Clamp check valve is also known as countercurrent valve, reverse check valve, back pressure valve, check valve. This kind of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, which belongs to an automatic valve.

H42(Y/W)

Vertical check valve

Vertical check valve: due to the pressure of the inlet medium in the pipeline, and overcome the spring resistance to open or close the valve. When the inlet end medium pressure is lower than the outlet end, the spring will push the valve core to the valve seat and make the valve close, prevent the medium from countercurrent, so the start and stop action. Vertical check valve is widely used in chemical, liquefied petroleum gas, fluid and other industries. Check valve according to the structure, can be divided into lifting type check valve, swing type check valve and butterfly check valve three.
