2. Product Overview
"Boang Brand" pneumatic fully welded ball valve is composed of a pneumatic actuator and an integrated welded ball valve. The power of the cylinder drives the ball to rotate, opening or closing the valve body passage to achieve fluid continuity. Low failure rate and easy operation. The ball pad is made of reinforced polytetrafluoroethylene. The valve stem adopts explosion-proof design. The products absorb advanced foreign technology and are developed based on domestic actual conditions. Domestic products replace imports and fill domestic gaps. Products are widely used in long-distance pipeline fields such as natural gas, petroleum, heating, chemical industry and thermal power pipeline networks.

4. Performance characteristics
) The ball valve is designed as an overall fully welded structure, which eliminates the leakage of the medium
) The spring-loaded floating valve seat uses soft sealing material as +% and as Seal, the valve seat is pushed tightly by the spring to closely fit on the surface of the ball. This technology also ensures reliable sealing of the ball valve even when the medium pressure is low
) It adopts a floating ball structure, and the valve stem and ear are used in excess of The shaft fixed ball ensures the position accuracy of ball valve balls of different sizes, that is, ensuring the sealing performance, low torque and operability of the ball valve
) The valve stem is made of replaceable rings and materials that are +% or flexible Graphite packing can be used for sealing, which can achieve multiple seals to ensure that the valve stem seal is leak-free. At the same time, the use of flexible graphite as a packing seal also has a fire-proof effect, and is especially suitable for use in gas systems.

Land, installation notes
The end welding of fully welded steel ball valves uses electric welding or manual welding. Overheating of the valve chamber should be avoided. The distance between welding ends cannot be too short to ensure that the heat generated during the welding process will not damage the sealing material. All valves should be opened during installation.
