Ball valve, the opening and closing part(sphere) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control.
Floating ball valves are mainly used to cut off or turn on the medium, and can also be used for fluid regulation and control. The ball of the floating ball valve has only the upper valve stem, and the ball can be slightly displaced, so it is called a floating ball valve.
The floating ball valve is small in size, light in weight and simple in structure. The ball of the floating ball valve has a free floating function, which can better ensure the sealing; the ball can be freely rotated in the seat sealing ring by means of the valve stem.
Trunnion mounted 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 harsh environment are specially designed for various corrosive and non-corrosive media.
The trunnion mounted ball valve body consists of a main valve body, two left and right sub-valves. The ball is a ball with a journal at the upper end and a shaft hole at the lower end. The upper part of the valve body has a stuffing box and is connected to the spherical journal.
A ball valve with a Trunnion mounted shaft, called a Trunnion mounted ball valve. Trunnion mounted ball valves are mainly used for high pressure and large diameter. Depending on the mounting of the seat seal, the trunnion mounted ball valve can be constructed in two configurations.
Trunnion mounted ball valves are mainly used in high pressure and large diameter ball valves. According to the installation of the seat ring, the trunnion mounted ball valve has two structures: a ball seat sealed in front of the ball and a valve seat sealed in the ball.
The trunnion mounted ball valve closing part is a ball, and the ball rotates around the center line of the valve body to open and close a valve. The trunnion mounted ball valve which is provide a trunnion mounted ball valve with reasonable design, firm structure, high sealing performance, effective operation torque reduction and long service life.
Do you want to know the characteristics and advantages of trunnion mounted ball valve? 1. Double sealing and discharging function; 2, reliable stem seal and low operating torque; 3, full diameter or reduced diameter; 4, the valve stem can be lengthened; 5. Flexible operation.
The ball of the floating ball valve is floating. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing surface at the outlet end to ensure the sealing of the outlet end.
