Cast Iron Ball Valve
Cast Iron Ball Valves are used in commercial, industrial, and process applications requiring a non-corrosive body finish or where a clean cosmetic appearance is desired.
Learn MoreThree Way Ball Valve
The three - way ball valve can be divided into L type and T type. The L type three way ball valve is used to switch the medium flow direction, so that the two vertical channels can be connected. The three way ball valve usually adopts the two seat structure, and it can also adopt four seat structure according to the user's request. The four valve seat sealing three ball valve has beautiful shape and compact structure. It can not only switch the flow direction of the medium, but also make the three channels interconnected. At the same time, it can close any channel, make the other two channels connected, and flexibly control the flow or shunt of the medium in the pipeline.
Learn MoreFloating DBB Ball Valve
The DBB double ball valve is designed to replace the complicated connection of multiple valves in the traditional pipeline. Reduce the leakage point in the system, quickly achieve emissions and shut down function. The DBB double ball valve saves the installation space limit. The installation program is simplified. Reduce the pressure of the pipe system. It is convenient to clean and maintain the instrument and reduce the cost. DBB double ball valve has two series of full diameter and reduced diameter. The inside diameter of the full diameter ball valve is in line with the inner diameter of the pipeline, not only with small fluid resistance, but also convenient for pipeline cleaning. The fluid resistance of the shrink ball valve is much lower than that of the same caliber cut-off valve. The weight of the ball valve is about 30% lighter than that of the same caliber ball valve, which effectively reduces the cost and price of production, thus it has been widely used.
Learn More3PC Forged Steel Ball Valve
KOSEN 3PC Forged Steel Floating Ball Valves has a good sealing performance, however, we need to consider whether the outlet side seat could bear the working pressure as the movable ball would nearly pass all the medium pressure to the seat. For this reason, the floating structure is generally for middle & low pressure working pressure.
