2. Overview of the product
"Boang Brand" Gas double radiator welded ball valve is a gas fully welded ball valve with radiator. It is mainly used to open the pipeline when repairing downstream pipelines or equipment after the valve is closed. The remaining gas inside is exhausted to ensure the safety of maintenance work, and it can also be used for gas replacement during pipeline operation. Do not open the protective cover on the upper end of the relief valve during installation and when relief is not needed to ensure smooth flow of the relief valve. If LPG air-mixing is transported in a pipeline, the relief pipe should be led out of the valve well and then the relief valve is opened. After the relief is completed, in order to prevent static electricity from accumulating on the upper end of the relief valve due to friction with the pipe wall during the release of the gas, a metal wire or wet cloth can be used to ground it. , to achieve the effect of releasing static electricity.
3. Performance characteristics
) With release device, flexible switch, small torque
) Welded as a whole, there will be no external leakage, etc.
) Made of pipes, with sufficient strength , low price, beautiful appearance, convenient construction
) When the valve is in the fully open or fully closed position, the drain plug can be opened. When opening the drain plug, have a wrench available to prevent the drain plug from popping off. The shut-off and bleed functions can be used to verify the sealing integrity of the valve. If the discharge from one end of the valve does not stop, the valve seat may be leaking.

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.
