All-welded ball valve (directly buried, released)
It is suitable for natural gas, gas, gas and other fluids which do not react with carbon steel.
All-welded ball valve (directly buried with pre-thermal insulation)
It is suitable for natural gas, gas, gas and other fluids which do not react with carbon steel.
All-welded ball valve (cylindrical, fixed)
The manufacturing process of cylindrical valve body structure is simple, which is convenient for assembly and positioning. The mold needed for manufacturing the blank is simple and it is convenient to fix the ball with the support plate.
All-welded ball valve (flange type, for heat supply only)
One-piece welded ball valve has no external leakage and other phenomena.

Fixed ball valve
Fixed ball valve is a new generation of high performance ball valve. It is suitable for long-distance pipelines and general industrial pipelines. Its strength, safety and resistance to harsh environment are specially considered in design. It is suitable for all kinds of corrosive and non-corrosive media.
Floating ball valve
1.The fluid resistance is low. The fluid resistance coefficient is equal to that of the pipe section with the same length. 2.Simple structure, small volume and light weight.

Welded eccentric semi-ball valve (directly buried)
近年来，我公司通过市场调研发现，常规法兰式半球阀安装维护时，需砌筑大型阀门井，安装工程量大，成本高，还在操作区形成了危险的密闭空间，不利于安全运营。
Welded eccentric semi-ball valve
General valve for urban heat supply: Be suitable for occasions with strict requirements, such as sewage treatment and paper pulp.
Top-mounted eccentric semi-ball valve
Low pressure loss: When it is fully opened, the water loss is zero, the channel is completely unblocked, and the medium does not deposit in the cavity of the valve body.
Side-mounted eccentric semi-ball valve
PQ47 eccentric semi-ball valve uses eccentric valve body, eccentric ball and valve seat. When the valve rod is rotating, the valve will be closed more and more tightly in the process of automatic centering on common track, realizing good sealing completely.
