2. Product Overview
"Boang Brand" directly buried ball valve for gas exhaust is pressed and formed from carbon steel seamless steel pipe. It is developed by absorbing advanced foreign technology and combining it with domestic actual conditions, replacing imported products with domestic products to fill the domestic gap. It is widely used in long-distance pipeline fields such as natural gas, petroleum, heating, chemical industry and thermal power pipeline networks. The valve stem is made of stainless steel and the valve body is made of stainless steel. They are precision machined and ground to have excellent sealing performance and corrosion resistance. The seal uses a carbon-reinforced bevel elastic sealing ring with negative pressure on the spherical surface, which enables the seal to achieve zero leakage and long service life. The connection methods of this valve include welding, flange, etc. for users to choose. The transmission mode adopts handle, turbine, pneumatic, electric and other transmission structures, and the switch is flexible and light. This valve has compact structure, light weight, easy heat preservation and easy installation.
3. Product use
City gas gas output pipelines, main lines and branch line supply pipes, etc.
Central heating large-scale heating equipment output pipelines, main lines, branch lines
Heat exchanger Opening and closing of pipelines and various circuits
Various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines in steel plants
Various industrial equipment, various heat treatment pipelines, various industrial gas and heat pipelines .
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.
