Electric sleeve control valve

Product Overview

The Electric Sleeve Regulating Valve is a high-performance flow control device designed for precise modulation of pressure, temperature, and flow rate in high-pressure differential and high-velocity fluid systems. Featuring a balanced sleeve-guided trim and electric actuator, it excels in reducing vibration and noise while maintaining stability in demanding industrial processes such as oil & gas, power generation, and chemical processing.

Applications

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

Power Plants: Steam flow regulation in turbines and boiler feedwater systems.

Chemical Processing: Handling corrosive media (acids, alkalis) with precise dosing.

Water Treatment: High-pressure pump discharge control and desalination systems.

Key Features

Sleeve-Guided Trim Design:

• Balanced Plug: Reduces dynamic fluid forces, enabling stable control under high ΔP (up to 100 bar).
• Multi-Port Sleeve: Ensures uniform flow distribution and minimizes cavitation/erosion.

Electric Actuator:

• Control Signal: 4-20mA, 0-10V, or digital protocols (HART, Modbus, Profibus).
• Positioning Accuracy: ±0.25% with adaptive PID tuning and real-time feedback.
• Power Options: 24VDC, 110VAC, 220VAC (IP67/IP68 waterproof rating).

Flow Characteristics:

• Linear, Equal Percentage, or Quick Opening trim options.
• Cv Range: 5 to 2000, adaptable to extreme flow conditions.

Robust Construction:

• Body Materials: Carbon steel (A216 WCB), 316L stainless steel, duplex steel (UNS S31803).
• Trim Components: Stellite-coated plug/sleeve for abrasion resistance.
• Seals: Graphite, PTFE, or metal-to-metal for high-temperature/pressure sealing.

Safety & Compliance:

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

Operational Advantages

High Stability: Sleeve-guided design minimizes plug vibration and wear.

Energy Efficiency: Balanced trim reduces actuator power consumption.

Adaptability: Customizable trim configurations for specific noise/cavitation control.

Smart Diagnostics: Actuator self-monitors valve health, alerting for predictive maintenance.
