O-shaped Pneumatic Ball Valves

Floating ball valve fit for various pipeline as like Class150~Class1500,PN16~PN100,JIS 10K~JIS 20K.

Floating ball valve fit for various pipeline as like Class150~Class1500,PN16~PN100,JIS 10K~JIS 20K, used for throw-off or connecting the medium in pipeline. And different material can be suited to the kinds of medium as water, steam, oil produce, nitric acid, acetic acid, oxide medium, carbamide, etc.

Floating ball valve has all-diameter and crinkled-diameter structure forms. Use for transporting viscidity and slag medium. The ball valve on pipeline should use all-diameter type for fixed wax shaving and sweeping derive passing. The pipeline which used for transferring gas or the medium that the physical performance is similar to water should adopt the crinkled-diameter ball valve. And for the 30% discount of less weight than that all-diameter ball valve, is good for reducing pipeline load and cost. The drive way of floating ball valve is manual, worm gear derive, pneumatic, electronic or hydraulic.

Characteristic

1,O-shaped floating type ball valves adopt all-diameter or crinkled-diameter structure for small flow resistance.

2,According to ISO5211 connecting standard, valve uses high flat structure for higher specialization in installing electric/pneumatic actuator.

3,Valve stem adopt inner install type and the thrust cushion structure of axle shoulder and PTFE (strengthen graphite), prevent valve stem been blow outbecause of inner pressure in pipeline, meanwhile the material of PTFE(or strengthens the graphite) reduces the on-off torque of valve, making operation more effective.

4,Possess fire safe and anti-static structure to avoid the electrostatic fired the inflammable medium. Set up with electric-guide spring between stem and body, stem and ball body as well to ensure the safety of system

5,Incombustible structure provided double protection. In case the sealing ring burned in the fire, all the sealing parts of the ball valve would form stiff seal structure of metal against metal.

6,Select pneumatic, electric, and pneumatic-adjusting type, or electric-adjusting type we produced, for details, pls refer to the parts of actuator andadjusting valve.
