Electronic three-way control valve

Product Overview

The Electronic Three-Way Control Valve is a multifunctional flow management device designed for flow mixing (converging) or flow splitting (diverting) in liquid, gas, and steam systems. Integrated with an electronic actuator and advanced control algorithms, it precisely regulates temperature, pressure, and flow distribution in HVAC, chemical processing, and industrial energy systems.

Applications

HVAC Systems:Mixing Mode: Blends hot and cold water for precise temperature control in heating/cooling circuits.Diverting Mode: Distributes flow between primary and secondary loops in hydronic systems.

Chemical Processing:Controls reagent mixing ratios in reactors or neutralization processes.

Power Generation:Manages condensate return and feedwater distribution in steam systems.

Industrial Processes:Splits flow for parallel processing lines or cooling tower distribution.

Key Features

Three-Way Functionality:

• • L-Port (Mixing): Combines two inlet flows into a single outlet with ±1% mixing accuracy.
  • T-Port (Diverting): Splits a single inlet flow into two outlets with adjustable ratio control.
  • Flow Capacity: Cv range 5 to 1200, supporting high-volume applications.

Smart Electronic Actuator:

• • Control Signals: 4-20mA, 0-10V, HART, Modbus, or Profibus protocols.
  • Positioning Accuracy: ±0.25% with self-tuning PID algorithms.
  • Power Options: 24VDC, 110VAC, or 220VAC (IP67/IP68 waterproof rating).

Flow Optimization:

• • Trim Options: Linear, equal percentage, or custom-characterized plugs.
  • Anti-Cavitation Design: Multi-stage trim reduces noise and erosion in high ΔP (≤80 bar) systems.

Robust Construction:

• • Body Materials: Carbon steel (WCB), 316L stainless steel, duplex steel (UNS S31803).
  • Trim Components: Stellite-coated plugs and seats for extended wear resistance.
  • Seals: Graphite, PTFE, or Kalrez® 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

Precision Control: Adaptive PID ensures ±0.25% accuracy in flow mixing/splitting.

Energy Efficiency: Maintains constant flow rates, reducing pump/compressor load.

Flexibility: Programmable to switch between mixing and diverting modes.

Smart Diagnostics: Real-time monitoring of torque, position, and seal health.
