The turnnion mounted ball valve has a floating valve seat. After being pressurized by the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the sealing. Bearings are usually installed on the upper and lower shafts with the ball, and the operating torque is small, which is suitable for high-pressure and large-diameter valves.…

Pneumatic ball valves are mainly used for cutting off in pipelines. It is fast and can distribute and change the flow direction of the medium well. Pneumatic ball valve is a new type of valve that has been widely used in recent years, mainly including pneumatic hard-sealed ball valve, pneumatic soft-sealed ball valve, pneumatic flanged ball valve, pneumatic forged steel ball valve, pneumatic high-…

Pneumatic ball valve is a kind of pneumatic valve, including hard-sealed pneumatic ball valve, pneumatic O-shaped cut-off ball valve, soft-sealed pneumatic ball valve, wafer type pneumatic ball valve, pneumatic floating ball valve, pneumatic three-way ball valve, pneumatic flanged ball valve, etc. According to the different balls, it can be divided into floating ball pneumatic ball valve, fixed ba…

The medium of the bellows globe valve is very important, so everyone knows how to choose the medium of the bellows globe valve? Let's have a look! This is also a concern of many consumers. When the medium is toxic, volatile, radioactive, or it is extremely expensive and not allowed to be leaked by the reciprocating valve stem, a bellows is often used to seal the valve cover.…

V-shaped ball valve is a kind of ball valve. The closing part is a hemisphere with a V-shaped opening and a sharp edge. During the rotation of the sphere, there is a wiping effect between the closing parts, which has a strong cutting force on the medium. In addition, it also belongs to the V-shaped ball valve, which is a fixed ball valve and a single-seat sealed ball valve.…

Silent check valves belong to the category of automatic valves. Their function is to prevent the medium in the pipeline from flowing back. It is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.…

Check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent the medium from flowing back. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is a kind of automatic valve, its main function is to prevent the back flow of the medium, prevent the pump and drive motor from reversi…

Check valve, also called check valve, is an automatic valve. It relies on the pressure of the flowing medium in the pipeline to push the valve disc to close and open the valve. When the medium stops flowing, the check valve disc closes and prevents The reverse flow of the medium in the pipeline plays a great role in ensuring the safety of the pipeline.…
