Electric Sleeve Control Valve

2025-06-18

The Electric Sleeve Control Valve serves as a core device in industrial fluid control, achieving high-precision flow regulation and stable operation through the deep integration of an electric actuator and sleeve-type valve plug structure. A cylindrical sleeve with symmetric balancing holes is installed inside the valve body, and the valve plug moves guided by the sleeve. When the electric actuator receives standard control signals like 4-20mA, it drives the valve plug to displace axially, changing the flow area between the sleeve and plug to precisely regulate fluid flow, pressure, or temperature.

Core Technical Advantages

Pressure Balance Design: Balancing holes in the sleeve offset part of the medium pressure on the plug, reducing the thrust requirement of the electric actuator, minimizing energy consumption, and extending equipment life—ideal for high-pressure differential conditions.

High Sealing & Low Noise: Replaceable soft or metal sealing structures achieve ANSI Class IV or higher leakage standards. The sleeve's throttling effect disperses fluid kinetic energy, reducing flow noise and preventing pipeline vibration.

Flexible Regulation Characteristics: By replacing sleeves with different orifice patterns (linear, equal percentage, etc.), it adapts to various process regulation needs, with a regulation ratio of up to 300:1.

Typical Application Scenarios

Petrochemical Industry: Precisely controls high-temperature, high-pressure, and corrosive media flow in refinery units, ethylene cracking furnaces, and other systems.

Power Energy Sector: Used for feedwater regulation in power plant boilers and steam temperature/pressure reduction systems to ensure stable operation of power generation equipment.

Metallurgical Industry: Handles flow regulation and pressure control of dusty, high-velocity media in blast furnace gas pipelines and cooling water systems.

Environmental Water Treatment: Regulates chemical dosing and circulating water flow in wastewater treatment plants to facilitate efficient purification processes.

With its excellent pressure balance performance, precise regulation capability, and modular design, the electric Sleeve Control Valve becomes an indispensable fluid control solution in complex industrial processes, especially for scenarios with strict requirements on stability and sealing.
