Electric Operated Soft Sealing Butterfly Valve
The electric operated soft seal butterfly valve uses the electric actuator as the driving device of the valve, and the rotating valve stem drives the butterfly plate to rotate within the range of 0-90 ° to complete the opening and closing of the valve. The electric actuator structure is generally provided with a manual operating device. In case of power failure, manual and electric switching can be carried out to ensure the operation of the valve in an emergency state. The valve structure is a flange type double eccentric soft sealing structure, which can be used as the shut-off valve, control valve and check valve of the pipeline system. Electric or other corresponding operation modes are recommended for large diameter butterfly valves with diameters exceeding DN600.

V-type Rubber Ring
V-type rubber ring is mainly used for the main seal of ball valve, and the materials are high-strength special fluororubber and ordinary fluororubber for customers to choose.

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.

Rubber Sealing Ring
Rubber sealing ring is mainly used for mechanical parts to prevent the leakage of liquid and gas media under static conditions. In some cases, it can also be used as a dynamic sealing element for axial reciprocating and low-speed rotating motion. Depending on the rubber material, the general use temperature can be from -55 ℃ to 250 ℃. It has good heat resistance, ozone resistance, oil resistance, vacuum resistance and various chemical corrosion resistance etc.

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.

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.

O-type Rubber Ring
O-type rubber ring is a kind of rubber ring with circular cross section. Because its cross section is O-shaped, it is called O-type rubber ring. (such as dynamic and static seals of water, oil, air, chemical gas, etc.)

Soft Seal Bi-direction Butterfly Valve
Butterfly valve is one of obstructing valves to connect or block the medium in the pipeline, it can also adjust the flow of medium in the pipeline. Its closing element (disc) is in the shape of disc that can revolve the axis itself to block the medium in the pipeline or adjust the flow.

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
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.
