Product Details

Product description
Pneumatic type fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipeline, the strength and safety, resistance to harsh environments and so in the design were special consideration, applicable to various corrosive and non corrosive media. It is compared with the floating ball, work force of fluid pressure before the valve resulting in the ball on the all pass to the bearing, will not make the ball move to the seat, so the seat small deformation, stable sealing performance, long service life, suitable for high pressure, large diameter occasions. Advanced spring pre - seat assembly, with self - tightening characteristics, to achieve the upper seal. Each valve has two seats, each direction can be sealed and thus the installation is not limited to the flow, is a two-way.

Valve maintenance
1. To ensure the pneumatic pipe valve installation location of the pipeline in the coaxial position and line two flanges should be maintained in parallel and confirm the pipelines can be under pneumatic pipe valve of its own weight. If it is found that the pipeline is not under pneumatic pipe valve weight, before installation pipeline is equipped with the corresponding support.
2 to confirm whether there are impurities in the pipeline, welding slag, etc., must be cleaned inside the pipeline purge.
3. Check the gas dynamic pipeline valve plate, and the gas dynamic pipeline ball valve fully open all closed several operations, confirmed the valve to work properly, and comprehensive inspection once all the details of the valve to ensure the valve intact.
4 remove the protective cover at both ends of the valve, check valve body is clean, clean body cavity, as a result of pneumatic pipe valve sealing surface is the ball shape, even if the tiny debris may also cause damage to the sealing surface.
5 pneumatic pipe ball valve flange and pipe flange between the pipeline design requirements for the installation of the sealing gasket.
6 bolts on the flange to be symmetrical, successive, uniform tightening.
7 after the installation is completed, start pneumatic valve open and close several times, it should be flexible, uniform force, pneumatic pipe ball valve working properly.
