Pipeline System Trunnion Mounted Ball Valve
The trunnion mounted ball valve is ball fixed with two floating valve seats structures movable under medium pressure. Under the medium pressure, push the ball closer to the seat to ensure sealing.

Casting / Forged Floating Ball Valve for sour, water & gas medium
The floating ball valve as an on/off control unit, its ball is floating, a floating ball is supported by two valve seats, under the medium force, the ball moves (floats) downstream of the fluid to maintain a close contact with downstream seat to achieve a reliable seal. The seat special design has the wearing complementary structure to ensure safe reliable sealing and long stable operation of this series of ball valve.

Forged Buried Fully Welded Body Ball Valve for oil & natural gas medium
This type valves are trunnion mounted, and are highly adaptable to changes in pressure and temperature. The valve stem is extended by the user requirements. Because the valve body material is the same as the pipe material, there will not be uneven stress, and no deformation due to the earthquake and vehicles passing through the ground, and the pipeline is resistant to aging. Underground fully welded ball valve can be directly buried underground, without building high large valve Wells, just set up small shallow Wells on the ground, greatly saving construction costs and engineering time.

District Heating Fully Welded Ball Valve
The district heating fully welded ball valve for urban heating has the characteristics of strict closure, no leakage, high reliability and long service life, which is widely used in urban directly buried hot water pipelines. Because the valve body material is the same as the pipe material, there will not be uneven stress, and no deformation due to the earthquake and vehicles passing through the ground, and the pipeline is resistant to aging.

DBB Valve (Double Block and Bleed Ball Valve) for oil & natural gas medium
DBB ball valve (Double Block and Bleed Ball Valve) is designed to replace the complex connection of multiple valves in the traditional pipeline. Reduce the leakage points in the system, and achieve the discharge quickly. The installation space is saved as much as possible. The installation procedure is simplified.

Thermostability Eccentric Half Ball Valve for particles, ash, fiber medium
Eccentric half ball valve self centering in the common trajectory using the eccentric body, eccentric ball & seat, and stem for rotational movement, the closing process is more and more tight, to fully achieve a good sealing purpose. The ball and the seat are completely separated, eliminating the wear of the sealing ring, and overcoming the wear problem between the traditional ball valve seat and the ball sealing surface, the non-metallic elastic material is embedded in the metal seat, the valve seat metal surface is well protected.
