Ⅰ. Pneumatic forged steel ball valve main applications
Pneumatic forged steel ball valves are widely used in petroleum, natural gas, medicine, food, hydropower, nuclear power, drainage, heating, metallurgy, and other industries. They are vital mechanical products for national defense construction.
Pneumatic forged steel ball valve has many advantages. The ball valve has vital functions, large circulation capacity, light weight, small size, reliable performance, remote control, etc. It is a good product for throttling, through-transfer and can regulate the flow.
Pneumatic forged steel ball valve sealing performance is also particularly strong. It can be divided into two forms: resilient seal and metal seal. A resilient seal valve means that the seal of the electric ball valve can be attached to the valve. And service life of metal seal form of the valve in general will be much longer than the resilient seal type of valve. Excellent sealing ability can well block the entry of air and maintain the internal sealing. That’s why many companies choose to use it in industrial automation.
Pneumatic forged steel ball valve is evolved from the plug, its opening and closing member is a ball, the use of the ball around the axis of the stem rotation 90° to achieve open and close. Pneumatic forged steel ball valve in the pipeline is mainly used to cut off, change the direction of media flow.The V-shaped opening of the ball valve also has a good flow regulation function.
The pneumatic forged steel ball valve has a simple structure, good sealing performance, and smaller volume in a certain nominal diameter range, light weight, less material consumption, small installation size, and small driving torque. It is easy to operate to achieve rapid opening and closing.
Ⅱ. The characteristics of pneumatic forged steel ball valve
- 1. A locking hole is provided in the valve’s fully open and fully closed position to prevent misoperation by non-staff.
- 2. Set up steps in the lower part of the valve stem, in case of the valve internal pressure abnormal rise off the stem.
- 3. A fire-resistant sealing ring between the ball and the valve seat. The burned valve seat is still has a sealing role.
- 4. Rapid switching, flexible opening and closing, long service life, safe and reliable.
- 5. Pneumatic forged steel ball valves can be controlled centrally from a distance, and can meet the needs of computer program control.
- 6. The fluorine plastic lining layer of the ball valve, with chemical stability, is suitable for any strong corrosive chemical media.
- 7. The use of full-pass floating ball valve structure, leak-free closure in the entire pressure range. It is convenient for the pipeline system to sweep the line and maintain the pipeline.
