  • Water Gate Valve

    Water Gate Valve

    The water gate valve is opened and closed by the up and down movement of the valve plate. The movement direction of the gate is perpendicular to the fluid direction. The gate moves up and down perpendicular to the center line of the valve channel, cutting off the medium in the pipeline like the gate, so it is called gate valve. The gate valve can only be fully opened and closed, but can not be adjusted and throttled.
  • Centerline Butterfly Valve

    Centerline Butterfly Valve

    Flange Centerline butterfly valve is a gate valve that has different modifications. The gate is in the shape of a disc that is attached to a centered axis. The look resembles a butterfly. The centerline design allows for the control of the fluid flow.
  • Cast Steel Globe Valves

    Cast Steel Globe Valves

    Cast Steel Globe Valves are linear motion closing-down valves in which the closure member is moved squarely on and off the seat. Usually the closure member is referred as a disc, irrespective of its shape.
  • Cast Iron Manual Ball Valve

    Cast Iron Manual Ball Valve

    Cast iron manual ball valve is a kind of ball valve, which has some advantages, such as no friction on the switch, seal is not easy to wear, small opening and closing torque and so on. Cast iron manual ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline.
  • Full Bore Ball Valve

    Full Bore Ball Valve

    Full bore ball valve is of equal width flow channel, and its size shall not be less than the value specified in the standard, which is approximately equivalent to the nominal diameter of the specification.
  • Compound Exhaust Valve

    Compound Exhaust Valve

    Compound exhaust valve is a kind of floating ball exhaust valve made by Bernoulli's theory, which can keep fully open under the air flow. When the solid water column rises, the floating ball can float immediately and close the exhaust port tightly. Compound exhaust valve adopts a specific diameter of floating ball, so that the aerodynamic force generated by it can keep the floating ball open when the air flows through, and the buoyancy generated when the solid water column rises can make it float again. With a cone at an appropriate angle at the inlet, the exhaust port will not be blocked no matter how high the air pressure or the air velocity.
