Four-way ball valve
Application
The four-way ball valve enables four orthogonal pipes to
communicate with each other in an industrial pipeline to change the
flow direction. It is widely used in industrial sectors and
automatic control systems such as metallurgy, mining, petroleum,
chemical, electric power, light industry, shipbuilding, etc. It is
suitable for working conditions of fluids, gases and 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.
5. When fully open or fully closed, the sealing surface of the ball
and valve body is isolated from the medium. When the medium passes,
it will not cause erosion of the sealing surface of the valve.
6, Easy to maintain. The ball valve has a simple structure, and the
sealing ring is generally movable, so that it is convenient to
disassemble and replace.
