The 47/48-41000 series pneumatic sleeve regulating valve is a new product introduced from Masoneilan Company in the United States. It is widely used for automatic regulation and remote control in industrial processes such as chemical, refining, metallurgy, and power plants.

The 47/48-41000 series pneumatic sleeve regulating valve consists of a ∑ F actuator and a 41000 series sleeve valve. The ∑ F actuator is a combination of a conventional spring film actuator and a force amplification system. It utilizes the lever principle to amplify the output force of the actuator by 2.6-5.2 times; The 41000 series sleeve valve is equipped with a cylindrical sleeve inserted into a single seat valve body, guided by the sleeve, and equipped with a valve core that slides up and down inside. The sleeve wall has specific flow characteristic windows, and the valve core moves up and down to change the flow area of the sleeve window, thereby achieving the purpose of regulating flow.

Key Features:
1. The rated flow coefficient is higher than other straight stroke regulating valves.
2. The valve core adopts a balanced structure and is equipped with a ∑ F actuator, allowing for the use of large pressure differentials.
3. The valve core moves inside the sleeve, with a large guiding area and good vibration resistance and wear resistance.
4. Separating the sealing surface and throttling surface in the structure reduces the erosion of the sealing surface when the medium flows, thereby improving the service life.
5. Strong adaptability, simply replacing the sleeve can meet the requirements of different flow coefficients and flow characteristics.
6. By using an auxiliary valve core, it can achieve tight cutting.
7. Easy to disassemble, inspect, and repair.
