Three-way ball valve
Application
The three-way ball valve functions as a split and merge in the industrial pipeline. The T-type enables three orthogonal pipes to communicate with each other and the third channel to be cut. The L-three-way ball valve can realize the switching of the medium flow direction in the pipe. It is also possible to connect or close two channels that are perpendicular to each other. It is widely used in metallurgy, mining, petroleum, chemical, electric power, light industry, shipbuilding and other industrial sectors and automation control systems, suitable for mixing, diverting conditions of fluids, gases, dust media.
Feature
1, The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2, Close and reliable. At present, the sealing surface material of the ball valve has a good sealing property of PTFE, and it is also possible to use a hard-sealed valve seat weld alloy to improve wear resistance. A coil spring is used to provide a sealing force to ensure sealing performance.
3, Using the upper and lower valve stem fixed design, which there are upper and lower bearing positioning, ensure good mechanical stability and small starting torque. The bearing material is made of composite material, and its rotating shaft bearing surface is treated with sintered PTFE, which has superior wear resistance and self-lubricating function. This avoids the seizure of the valve during long-term use.
4, It is easy to operate and can be opened and closed quickly. From full-open to full-close, the spool rotates 90 degrees. Manual, pneumatic and electric actuators can be installed to facilitate remote control.
