Product Overview

The Electronic 3-Way Control Valve is a versatile flow management device for flow mixing (confluence) or diverting (shunt) in liquid, gas and steam systems. The valve incorporates an electronic actuator and advanced control algorithms to precisely regulate temperature, pressure and flow distribution in heating, ventilation and air conditioning (HVAC), chemical processing and industrial energy systems.

Applicable working conditions

HVAC systems: Mixing mode: mixes hot and cold water for precise temperature control of the heating/cooling circuits. Shunt mode: distributes the flow between the primary and secondary circuits in plumbing and heating systems.

Chemical processes: control of reagent mixing ratios in reactors or neutralization processes.

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

Industrial processes: Distribute diversions for parallel process lines or cooling towers.

Main features

Tee function:

L-Port (Mix): Combines two inlet flows into a single outlet with a mixing accuracy of ±1%.
T-Port (Split): splits a single inlet flow into two outlets with adjustable proportional control.
Flow: Cv values range from 5 to 1200 to support high traffic applications.

Intelligent electronic actuator:

Control signal: 4-20mA, 0-10V, HART, Modbus or Profibus protocol.
Positioning accuracy: ±0.25%, using self-regulating PID algorithm.
Power options: 24VDC, 110VAC or 220VAC (IP67/IP68 waterproof rating).

Flow Optimization:

Valve insert options: linear, equal-percentage, or custom spool.
Anti-cavitation design: Multi-stage valve internals reduce noise and corrosion in systems with high differential pressure (ΔP) (≤80 bar).

Sturdy and durable:

Valve body materials: carbon steel (WCB), 316L stainless steel, duplex steel (UNS S31803).
Valve internals: Stellite alloy coated spool and seat for greater wear resistance.
Seals: Graphite, PTFE or Kalrez? 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

Precise control: Adaptive PID control ensures flow mixing/splitting accuracy of ±0.25%.

Energy saving: maintains a constant flow rate and reduces pump/compressor loads.

Flexibility: Programmable switching of mixing and shunting modes.

Intelligent diagnostics: real-time monitoring of torque, position and seal status.
