Product Overview

The Electric Sleeve Control Valve is a high performance flow control device designed to precisely regulate pressure, temperature and flow in high differential pressure and high velocity fluid systems. Featuring a balanced sleeve-guided spool and motorized actuator, the valve effectively reduces vibration and noise while maintaining stability in demanding industrial processes such as oil and gas, power generation and chemicals.

working condition

Oil & Gas: Precise control of crude oil, natural gas and refinery processes.

Power plants: steam flow regulation in turbine and boiler feedwater systems.

Chemical processing: precise metering for handling corrosive media (acids, alkalis).

Water treatment: high-pressure pump discharge control and desalination systems.

Main features

Sleeve guided valve inner member design:

Balanced Plug: Reduced dynamic fluid forces for stable control at high differential pressures (up to 100 bar).
Porous Sleeve: Ensures uniform flow distribution and minimizes cavitation/corrosion.

Motorized actuators:

Control signal: 4-20mA, 0-10V or digital protocol (HART, Modbus, Profibus).
Positioning accuracy: ±0.25%, with adaptive PID regulation and real-time feedback function.
Power options: 24VDC, 110VAC, 220VAC (IP67/IP68 waterproof rating).

Flow characteristics:

Linear, Equal Percentage, or Rapid Open valve insert options.
Cv range: 5 to 2000 for extreme flow conditions.

Sturdy and durable:

Valve body materials: carbon steel (A216 WCB), 316L stainless steel, duplex steel (UNS S31803).
Valve internals: Stellite alloy coated spool/bush, wear resistant.
Seals: Graphite, PTFE or metal-to-metal seals for high temperature/high pressure environments.

Security and Compliance:

Certifications: ATEX, IECEx (Zone 1/2), SIL2/3 (IEC 61508).
Standards: API 598, ANSI B16.34, ISO 5208.

Product Advantages

High stability: Sleeve-guided design minimizes spool vibration and wear.

Energy saving: Balancing the valve internals reduces the power consumption of the actuator.

Adaptability: Valve insert configurations can be customized for specific noise/cavitation control.

Intelligent Diagnostics: The actuator can self-monitor valve health and issue early warnings for predictive maintenance.
