The spool ball of the floating ball valve moves between the two seat sealing rings with the help of medium pressure, while the spool ball of the trunnion mounted ball valve is connected with the valve stem and rotates around the center of the valve stem, and the floating seat support ring. Floating Ball Valve The ball of the floating ball valve is floating. Under the action of medium pressure, the...

In steam and condensate systems, garbage and debris in pipelines often cause damage to equipment, such as scale, rust, welding slag, and other solid particles, which may enter the pipeline system. Strainers can filter out solid particles in liquids or gases, not only protecting equipment from damage, but also reducing equipment downtime and maintenance time. Strainers are generally installed upstr...

1. Non rising stem gate valve: The stem nut is located inside the valve body and in direct contact with the medium. When opening and closing the gate, rotate the valve stem to achieve this. The advantage of this structure is that the height of the gate valve remains constant, so the installation space is small, making it suitable for gate valves with large diameters or limited installation space. ...
