Buried underground ball valve construction drawings 
 Modern city inside the vehicle and pedestrian traffic density, road conditions are very complex. 
 Therefore, the construction and maintenance of gas supply pipes and heating supply pipeline construction time and construction of its security requirements is very high. 
 The all-welded ball valve, can be directly buried deep underground. Construction using the latest engineering technology and methods to maximize the reduction of space occupied by the valve control, and saves construction costs and engineering time. But also prevent the risk of gas explosion, all welded ball valves are very safe. 
 Buried valve drive, the operator does not need to enter the underground, just on the ground to drive operations can be very safe and convenient. 



 The design of a common valve valve well is much higher than the cost price of the valve itself
