2205 ball valve,duplex stainless steel Ball Valve

 duplex stainless steel Ball Valve includes 2205,2507, 1.4529, F51, F53, F55, F60, 4A, 5A, 310S, 2520 and other material threads, internal threads, external threads, welding, high-pressure hard seal soft seal high platform pneumatic electric dual phase steel ball valve. Caliber 1/8~2 “, pressure 150LB~2500LB.

duplex stainless steel Ball Valve is small in size and adopts a high platform connection structure. Its advantage is that it does not need to remove the pipeline thread during maintenance and disassembly, but directly remove four bolts, and the middle part of the valve body can be taken out. The working principle is to drive the rotation of the sphere through the pneumatic and electric rotation of the handle to achieve the flow and blocking of the medium, which is applicable to the small volume and narrow space of light industrial machinery.

At present, the valve is widely used in industrial automatic control systems of food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power and other industries.

Features of duplex stainless steel Ball Valve:

1. The fluid resistance is small, and the full bore ball valve basically has no flow resistance.

2. Simple structure, small volume and light weight.

3. Tight. It has two sealing surfaces. At present, the sealing surface of the ball valve is made of plastic, which has good sealing performance and can realize sealing. It has also been used in vacuum systems.

4. It is easy to operate and fast to open and close. Only 90 ° rotation is required from full open to full close, which is convenient for remote control.

5. It is easy to maintain, the ball valve is simple in structure, the sealing ring is generally movable, and it is convenient to remove and replace.

6. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.

7. It is applicable to a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.

8. The ball valve can be used in medium with suspended solid particles due to its wiping property during opening and closing.

Structural of duplex stainless steel Ball Valve:

1. There is no friction when opening and closing. This function completely solves the problem that the sealing of traditional [wiki] valves [/wiki] is affected by the friction between sealing surfaces.

2. Top mounted structure. The valves installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.

3. Single seat design. The utility model eliminates the problem that the medium in the valve cavity affects the use safety due to abnormal pressure rise.

4. Low torque design. The valve stem with special structure design can be easily opened and closed by a small handwheel valve.

5. Wedge seal construction. The valve is sealed by pressing the ball wedge onto the valve seat with the mechanical force provided by the valve stem, so that the sealing performance of the valve is not affected by the change of pipeline differential pressure, and the sealing performance is reliably guaranteed under various working conditions.

6. Self cleaning structure of sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through the valve seat 360 ° evenly along the sealing surface of the ball, which not only eliminates the local scouring of the valve seat by high-speed fluid, but also washes away the deposits on the sealing surface, so as to achieve the purpose of self-cleaning.
