Overview

Pneumatic ball valve supply $r $n German VATTEN pneumatic segmented ball valve can achieve two opening and closing of the ball valve between 0 and 90 degrees, achieving control of the flow inside the pipeline. It is generally used in bulk systems of petroleum and chemical products.

Product Details

Pneumatic ball valve supplyIt is composed of a segmented three position pneumatic actuator and a stainless steel ball valve. The three position pneumatic actuator provides an operating mode of 0 ° -45 ° -90 ° or 0 ° -90 ° -180 °, which can achieve adjustable intermediate positions such as 30 °, 50 °, 75 ° through mechanical braking generated by the movement of two auxiliary pistons. The installation of pneumatic actuators on valves must consider the operating torque of the valve plus the manufacturer's recommended safety factor. The structural principle of ball valves determines that the torque required to operate the valve is determined by the friction between the ball core and valve seat, as well as between the valve stem and packing. The maximum torque occurs when there is a pressure difference and the ball core rotates in the open direction from the closed position. Choosing a three-stage ball valve can achieve two opening and closing of the ball valve between 0 ° and 90 °, thereby controlling the flow rate inside the pipeline and reducing the impact on the equipment Due to its ability to open and close the ball valve twice between 0 ° and 90 °, the three position pneumatic segmented ball valve can control the flow inside the pipeline, making it widely used in bulk systems for petroleum and chemical products.

Pneumatic ball valve supplyCharacteristics:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable, the sealing surface material of ball valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy to maintain, pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.

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

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

8. Because the power source of pneumatic ball valves is gas, usually at a pressure of 0.2-0.8MPa, it is relatively safe. If a pneumatic ball valve leaks, compared to hydraulic or electric valves, the gas can be directly discharged without polluting the environment, and it has higher safety.

Compared to manual and turbine ball valves, pneumatic ball valves can be configured with larger diameters (manual and turbine ball valves are generally below DN300 diameter, while pneumatic ball valves can reach DN1200 diameter)
