Full Weld Ball Valve

Description

Fully welded ball valve will be no external leakage. Ball is high precision processing. Advanced computer detector tracks and detects the process of ball processing. Stress would not be uneven since the body material is the same with the pipe material.

Structural Chracteristic

The structural features of fully welded ball valve still include the following besides the above-mentioned advantages of fixed ball valve: it adopts the fully welded structure without middle flange leakage and is connected to the pipeline with butt welding or flange connection. The former is free of the leakage of the flange connection between pipeline and valve while the former is easy for valve disassembly and maintenance. According to different working media, the materials for seat sealing surface can adopt PTFE, nylon, alloy steel, STL and so on, which can meet different requirements for temperature, pressure and corrosion within a large range. Different actuator modes are adopted to meet the valve control requirement by different working conditions. And the biggest feature is that its weight is about 10%-20% lighter than that of the bolt structure type, and that it has such advantages as compactness, light weight, beautiful appearance and being lasting and durable compared with the normal ball valves with the same specifications. Having a long service life计is widely applied in natural gas long-distance and buried pipelines with serious corrosion containing such gases as hydrogen sulfide; the ball valve with fully welded body can be buried underground directly to free its internal components from erosion and it has a service life as long as 30 years, which is the optimal valve for petroleum and natural gas pipelines.
Our fully welded ball valve is mainly divided into three structural types: plate welding, forge welding and cast welding. It is widely applied in buried pipelines for water delivery, chemical engineering, petroleum and natural gas, which can extend the interval of replacing and overhauling the valve. It has been well-received by nomerous users by right of its high quality.
