M-series Pneumatic Sleeve Regulating Valve

The M series pneumatic sleeve regulating valve developed and manufactured by our company is a pressure balance type control valve. It features a sleeve-guided, pressure balance double-seal spool structure with a streamlined S-shaped flow channel. The multi-spring actuator ensures stable overall performance. This valve can handle high pressure differences, provides accurate flow control, and operates with low noise levels. It is particularly suitable for applications requiring large flow rates and significant pressure differentials between the inlet and outlet of the valve, where strict leakage requirements are not necessary. Our products find extensive use in automatic control systems within industries such as chemical processing, petrochemicals, chemical fibers, electric power generation, metallurgy, and environmental protection，etc.

【Product Characteristics】

1.The flow channel is designed with an S-shaped structure to effectively mitigate vortex formation resulting from the complex shape of the flow path and irregular flow patterns caused by sudden expansions, ensuring efficient and stable medium flow.

2.This design features modular components with strong interchangeability and versatility; different sleeves can be replaced to achieve varying flow coefficients and characteristics.

3.It incorporates a balanced structure that significantly reduces unbalanced forces on the spool, while also providing damping operation for stable control valve performance. Special symmetrical holes within the valve interior reduce noise, further achieving pressure reduction to prevent flash and cavitation, making it particularly suitable for high-pressure difference, low-noise applications.

4.The valve seat is compressed onto the valve body through the valve cover without threaded connections, facilitating easy installation and maintenance.

5.Utilizing a simple mechanical structure of a multi-spring type small film actuator with large output force has allowed for reduced valve height and achieved miniaturization.

6.By utilizing high-precision IEC standard technical parameters as the basis for its characteristic curve, this design theoretically realizes “ideal” flow leading to stable process gain. Flexible control under computer simulation in process control of valve opening can thus be achieved.
