  • Flanged / Wafer Type Triple Eccentric Butterfly Valve for sour and alkaline medium

    Flanged / Wafer Type Triple Eccentric Butterfly Valve for sour and alkaline medium

    Triple eccentric butterfly valve, the valve stem shaft center deviates from the center of the plate and the body center, and the seat rotation axis has an angle from the axis of the body channel. When the valve is fully open, the plate sealing surface will completely deviate from the seat sealing surface. When the plate opens from 0 to 90 degrees, the plate sealing surface gradually leaves the seat sealing surface, and the valve opens. When the plate opens from 90 to 0 degrees, the plate sealing surface gradually approaches the seat sealing surface, and then press and the valve closes.

  • Casting Steel Parallel Type Gate Valve for sour and alkaline medium

    Casting Steel Parallel Type Gate Valve for sour and alkaline medium

    Parallel type gate valve is a sliding valve that closing part is a parallel gate. The closure may be single or double gate with a supporting mechanism. The compression force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or floating valve seat. If it is a double gate valve, the support mechanism between the two gates can supplement this pressing force.

  • Casting / Forged Floating Ball Valve for sour, water & gas medium

    Casting / Forged Floating Ball Valve for sour, water & gas medium

    The floating ball valve as an on/off control unit, its ball is floating, a floating ball is supported by two valve seats, under the medium force, the ball moves (floats) downstream of the fluid to maintain a close contact with downstream seat to achieve a reliable seal. The seat special design has the wearing complementary structure to ensure safe reliable sealing and long stable operation of this series of ball valve.

  • Wafer Type Knife Type Gate Valve for fluids containing solids (particles, dust & pulp)

    Wafer Type Knife Type Gate Valve for fluids containing solids (particles, dust & pulp)

    Knife gate valve is also known as knife type gate valve, slurry valve and mud valve. It’s opening & closing element is gate. The movement direction of the gate is perpendicular to the fluid direction. The medium is cut off by a knife edge gate that can cut fiber materials. The gate has two sealing surfaces. When the knife gate valve is closed, the sealing surface can be sealed only by medium pressure, That is, rely on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of valve, this is self-sealing. Most gate valves are using forced sealing, that is, when the valve is closed, rely on external force to force the gate to the valve seat to ensure the tightness of the sealing surface.

  • Tilted Plate Rubber Sealed Butterfly Valve

    Tilted Plate Rubber Sealed Butterfly Valve

    The tilted plate soft seal butterfly valve is a product developed by our company for foreign customers and continuously optimized. It can be widely used in water supply and drainage, petroleum, chemical industry, electric power, municipal construction and other pipelines in domestic and foreign for cutting off or regulating the medium flow. The product has undergone a long-term practical test, and its performance has been in the leading level at home and abroad.

  • Forged Buried Fully Welded Body Ball Valve for oil & natural gas medium

    Forged Buried Fully Welded Body Ball Valve for oil & natural gas medium

    This type valves are trunnion mounted, and are highly adaptable to changes in pressure and temperature. The valve stem is extended by the user requirements. Because the valve body material is the same as the pipe material, there will not be uneven stress, and no deformation due to the earthquake and vehicles passing through the ground, and the pipeline is resistant to aging. Underground fully welded ball valve can be directly buried underground, without building high large valve Wells, just set up small shallow Wells on the ground, greatly saving construction costs and engineering time.

  • Ductile Iron Flanged Soft Seal Gate Valve for water treatment system

    Ductile Iron Flanged Soft Seal Gate Valve for water treatment system

    The opening and closing element of the soft seated gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only fully open and close, and cannot used to adjust and throttle. The gate has two sealing surfaces. The most commonly used mode: the two sealing surfaces of the gate form a wedge, and the wedge angle varies with the valve parameters.

    The gate of wedge gate valve can be made into a whole, which is called solid gate valve; It can also be made into a gate that can produce slight deformation to improve its manufacturability and make up for the deviation of the angle of the sealing surface during processing. This gate plate is called flexible gate valve.

  • District Heating Fully Welded Ball Valve

    District Heating Fully Welded Ball Valve

    The district heating fully welded ball valve for urban heating has the characteristics of strict closure, no leakage, high reliability and long service life, which is widely used in urban directly buried hot water pipelines. Because the valve body material is the same as the pipe material, there will not be uneven stress, and no deformation due to the earthquake and vehicles passing through the ground, and the pipeline is resistant to aging.

  • Flanged/BW/NPT Forged Globe Valve for water, steam, air & oil

    Flanged/BW/NPT Forged Globe Valve for water, steam, air & oil

    Forged globe valve is the valve where the closure (disc) moves along the centerline of the seat. According to this form of movement of the disc, the change of the valve seat opening is in the direct proportion to the disc stroke. Because the globe valve has a relatively short open or closing stroke, and has a very reliable cut-off function, it is very suitable for flow adjustment. Therefore, this type of valve is very suitable for cut-off or adjustment as well as throttling.

  • Wafer Type Dual Plate Swing Check Valve for sour and alkaline medium

    Wafer Type Dual Plate Swing Check Valve for sour and alkaline medium

    The dual plate check valve is also a swing type check valve, but it has double discs, D-shaped disc with two spring-bearing, which is placed on the bar shaft across the valve bore and closed by the spring. Due to the spring load, this valve reacts very quickly to the backflow. This structure reduces the distance from which the valve center of gravity moves and reduces the valve weight. The valve is simple, small and light weight.
