2. Product Overview
"Boang Brand" underground double relief ball valve is a new type of energy-saving cut-off gas valve developed by our company by introducing advanced foreign design technology and equipment. Regardless of whether the valve is in the open or closed position, the upstream and downstream pressure can discharge the internal pressure through the relief valve to protect the equipment from damage caused by a sharp increase in pressure. It is a gas ball valve with relief, including a ball valve body. A long center column with a pipe joint is connected to the switch joint of the ball valve body. The long center column includes a long center cylinder, and a protective tube is wrapped around the ball valve body. The controlled pipeline is equipped with a discharging unit device, which includes a discharging base connected with the pipe, and a discharging pipe placed on the discharging base. A discharging valve is provided at the upper end of the discharging pipe, and the discharging unit device is connected to the long stem through a bracket. They are fixed to each other, practical, easy to use, easy to open and close, and are conducive to pipeline inspection.

4. Technical features
, with release device, flexible switch, small torque
, integrally welded, no external leakage, etc.
, made of pipes, with sufficient strength , low price, beautiful appearance, convenient construction
Welded ball valves can be buried directly underground. There is no need to build high and large valve wells. Only small shallow wells need to be set up on the ground, which greatly saves construction costs and engineering time.

Land and installation precautions
/> 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.
