The Design Features of On Off Ball Valve With Pneumatic Actuator:

1.Valve stem anti-blowing structure design:
The valve stem adopts the anti-blowing structure design, and the valve stem with the big upper end and the small lower end is positioned under the upper end cover and the screw, so that the valve stem can not be blown out by the medium even if the valve chamber is abnormally boosted(check the Figure 1).

2.Anti-static design:
The pneumatic operated ball valve adopts an anti-static design to form a static passage through the ball, the valve stem and the valve body. Therefore, the electric power generated by the rubbing during the switching process between the ball and the valve seat is led to the ground through the valve body, thereby preventing the fire or explosion hazard which may be caused by the static spark(check the Figure 2).

3.Fireproof structure design:

When a fire occurs, when the valve seat and seal made of non-metallic material are damaged at high temperature, the specially designed metal-to-metal auxiliary sealing structure effectively prevents a large amount of leakage of the medium.

4.The standard ISO-5211 connect plate is designed to facilitate the customer to change the operation mode at any time.

Product Characteristics of On Off Ball Valve with Pneumatic Actuator:

1. The valve body is produced by precision casting or forging,so the on off ball valve with pneumatic actuator has compact structure and beautiful appearance. The fixed O-type ball valve ball and the valve stem make a rotary motion. When the ball is rotated, the valve seat is always in close contact and has a strong cutting capability;

2. The valve seat is preloaded by a cylindrical spring or a butterfly spring. It has automatic compensation, self-sealing and automatic pressure relief function in the valve cavity. It is suitable for high temperature and high pressure applications.

3.A variety of sealing structures can be selected to ensure the service life and reliability of the pneumatic operated ball valve.The sealing type is available in soft and hard seal, and the sealing surface can be hardened for a variety of operating conditions.

4.The automatic pressure relief design of the valve cavity: when the temperature of the medium staying in the valve body cavity rises and causes abnormal pressure rise, the safety valve is not required, but the valve seat function can automatically relieve pressure, thereby improving the safety of the the on off ball valve with pneumatic actuator.

5.Fireproof structure,anti-static structure, anti-blowing stem structure design can be selected. For theon off ball valve with pneumatic actuator,it adopts ISO 5211 actuator installation standard.

6.For ourpneumatic operated ball valve,the stem length can be extended to suit cryogenic applications.
