2PC Pneumatic Control Flange End Stainless Steel Ball Valve
Summary:
Q641F/H pneumatic flange ball valve adopts high precision pneumatic actuator and cast ball valve. It is mainly divided into two categories: pneumatic soft seal ball valve and pneumatic hard seal ball valve. Structure of pneumatic flanged ball valves have tight ling, small volume, reliable operation, the flow coefficient is low., good sealing, easy maintenance, easy installation, strong adaptability, etc. Pneumatic flange ball valve can be equipped with travel limit opening, magnetic valve, pressure reducing valve and gas source of 0.4-0.7mpa to realize opening and lifting, and send two pairs of passive contact signals indicating the opening of the valve. Pneumatic flanged ball valves particularly suited to medium star sticky situations, including particle and fiber properties of pneumatic flanged ball valves, pneumatic sealing ball valves, pneumatic hard seal ball valve is widely used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, Qiao medicine made of silver, and other industrial automatic control Qiao system, long-distance centralized control and local control.

Advantages:
1. Small fluid resistance, the ball valve is all the valve class of the least fluid resistance. Even if it is a reduced diameter ball valve, the fluid resistance is also quite small.
2. Thrust bearing reduces the friction torque of the stem, which can make the stem balance and flexible in long-term operation.
3. The valve seat sealing performance is good, using PTFE and other materials made of the sealing ring, the structure is easy to seal, and the ball valve sealing ability increases with the increase of medium pressure.
4. Reliable stem seal, because the stem only for rotary and do not do lifting movement, stem packing seal is not easy to damage, and the sealing capacity increases with the increase of medium pressure.
5. PTFE and other materials have good self-lubrication, small friction loss with the ball, which can extend the service life of the ball valve.

6. Lower mounted stem and convex step on stem head prevent stem from ejection. In case of damage to stem seal caused by fire, metal contact can be formed between convex step and valve body to ensure stem seal.
