The sleeve control valve is a valve with a sleeve structure. It has the characteristics of small size, light weight, sensitive and reliable action, and good sealing performance. This kind of valve is suitable for regulating flow and pressure in various industrial pipelines that require high flow and pressure or have large leakage and do not allow backflow.

The sleeve and valve disc of the sleeve control valve have a clearance fit. There are multiple throttling windows on the sleeve. The shape of the window determines the flow characteristics of the control valve. The area of the window affects the flow coefficient Cv of the control valve. The valve seat adopts a self-centering, threadless snap-in structure. The conical sealing surface on the valve seat cooperates with the conical sealing surface on the valve disc to form a cut-off seal pair, ensuring that the valve is tightly shut off when the valve disc is pressed against the valve seat. There are symmetrically distributed balance holes on the valve disc parallel to the axial direction, which connect the chambers on the upper and lower end surfaces of the valve disc. In this way, the axial force of the medium in the valve on the valve disc mostly cancels each other out, and the inconsistency generated by the medium on the valve stem is eliminated. The balance force is very small.

The product features of sleeve regulating valve are as follows:

1. Small fluid resistance: Since the shape of the inner cavity is a straight cylinder, the fluid forms a flow state similar to an open channel when flowing through it, so the power consumption required to pass through its outlet is low.

2. Applicable to a variety of media: It can be used to control air, water, steam and other media, as well as various corrosive and non-corrosive media.

3. Wide scope of application: It can be used in various industrial pipelines such as petroleum processing equipment, power station boilers, chemical production, etc.

4. Moderate working temperature: suitable for regulating medium flow on various pipelines with working temperature ≤120°C (±5°C allowed) and nominal diameter ≤50mm.

5. Excellent regulating performance: The channel area of the throttling window on the sleeve can be changed, thereby realizing functions such as regulating the flow and pressure of the medium in the pipeline.

6. Small size and light weight: easy to install and maintain, saving space and cost.

7. Sensitive and reliable action: using advanced control systems and actuators to ensure quick response and precise control of the valve.

8. Good sealing performance: Using high-quality sealing materials and advanced sealing technology to ensure that the valve maintains good sealing performance during long-term use.

In general, the sleeve regulating valve is an efficient and reliable valve that is widely used in various industrial pipelines to meet different flow and pressure regulation needs.
