M series electric sleeve control valve
The M series electric sleeve control valve is a pressure-balanced type control valve. It adopts a sleeve guided and pressure-balanced double-sealed valve core structure. The flow channel is in an S streamlined shape, and the overall operation is stable. It features a large allowable pressure difference, precise flow rate and low noise. It is particularly suitable for large flow rates and significant pressure differences before and after the valve. In situations where the requirements for leakage are not high. The products are widely applied in the automatic control systems of industrial sectors such as chemical engineering, petrochemicals, chemical fibers, power, metallurgy, and environmental protection.

【 Product Features 】
1) The flow channel adopts an S-shaped structure, which can suppress the vortex generated by the complex shape of the flow path and the complex and irregular flow caused by the sudden expansion of the flow path, thereby achieving efficient and stable medium flow.
2) It adopts a modular design, featuring strong interchangeability and universality. By replacing different sleeves, different flow coefficients and flow characteristics can be obtained.
3) Balanced structure: Significantly reduces the unbalanced force acting on the valve core; Meanwhile, it also features damping operation, which is conducive to the stable operation of the control valve. Therefore, it can be used in applications with large pressure differences and low noise.
4) Easy installation and maintenance: The valve seat is pressed against the valve body through the valve cover without using threaded connection, making installation and maintenance convenient
