Pneumatic with manual ball valve,manual ball valve, ball valve

Pneumatic ball valves with manual operation are used to cut off or connect the medium in pipelines. By choosing different materials, pneumatic ball valves can be respectively applied to various media such as water, steam, oil products, nitric acid, acetic acid, oxidizing media, and urea. Pneumatic flanged ball valves can be widely applied in the automatic control systems of industrial sectors such as papermaking, petrochemical, chemical, metallurgy, power, environmental protection, petroleum, and light industry.

Advantages

The fluid resistance is small. Ball valves are one of the types of valves with low fluid resistance. Even for reduced-bore ball valves, their fluid resistance is quite small.

2. The thrust bearing reduces the frictional torque of the valve stem, enabling the valve stem to operate smoothly and flexibly for a long time.

3. The valve seat has excellent sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal. Moreover, the sealing capacity of the ball valve increases with the rise of the medium pressure.

4. The valve stem seal is reliable. As the valve stem only rotates and does not move up and down, the packing seal of the valve stem is not easily damaged, and the sealing capacity increases with the increase of the medium pressure.

5. Due to the excellent self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, thus the service life of the ball valve is long.

6. The bottom-mounted valve stem and the protruding steps at the head of the valve stem prevent the valve stem from erupting. In case of fire causing damage to the valve stem seal, the protruding steps can still form a metal contact with the valve body to ensure the valve stem seal.

7. Anti-static function: A spring is set between the ball, the valve stem and the valve body to discharge the static electricity generated during the opening and closing process.

Introduction to the Executive Agency

Series GT pneumatic actuators, available in double-acting and single-acting (spring return) types, featuring rack and pinion transmission, are safe and reliable. The AW type pneumatic actuator of the large-diameter valve series features a fork-pull transmission, a reasonable structure, and a large output torque. It is available in double-acting and single-acting types.

Gear-type double piston, with large output torque and small volume.

2. The cylinder is made of aluminum alloy, which is light in weight and beautiful in appearance.

3. Manual operating mechanisms can be installed at the top or bottom.

4. The rack-type connection can adjust the opening Angle and rated flow.

5. The actuator can be optionally equipped with electrical signal feedback indication and various accessories to achieve automated operation.

6. The ISO5211 standard connection provides convenience for the installation and replacement of the product.

The adjustable screws at both ends enable the standard product to have an adjustable range of ±4° between 0° and 90°. Ensure the synchronization accuracy with the valve.

It is a ball valve with the valve seat as the sealing material and sealed with polytetrafluoroethylene of similar products, and its service life has been increased by 3 to 5 times. It has the advantages of stable performance, reliable sealing, low friction, easy operation, high temperature resistance, wear resistance, oil resistance, corrosion resistance and long service life. The high-temperature ball valve is in line with the structural length of the stop valve, plunger valve and blowdown valve, which expands the application range of the ball valve
