The Difference Of Control Valve’s SLEEVE & CAGE.

The sleeve is an important component of the control valve. It is usually a cylindrical structure and is installed inside the valve body of the control valve. There are holes or openings of various shapes on the wall of the sleeve, and the design and distribution of these holes have a crucial impact on the flow characteristics of the fluid.

Elaboration On The Selection Criteria For Control Valves

Process conditions are the fundamental basis for the selection of control valves.
Temperature:Different temperature ranges have different requirements for the materials of control valves. For high-temperature media, high-temperature-resistant materials such as special alloy steels are needed to ensure that the valve will not deform or be damaged at high temperatures and to guarantee its sealing performance and operational performance.

Usages And Applications Of Fluorine-Lined Valves

Fluorine-Lined valve is a kind of valve with special lining material, mainly used to control the flow and pressure of various corrosive media.The lining inside the valve,made of a special polymer like PTFE/PFA(perfluoroalkoxy),increases the valve’s resistance to factors that can cause damage.
