Product Overview

Three way shunt and confluence control valve produced by TangoValve Group have two action modes, three-way confluence and three-way shunt, which can replace two two-way valves and a three-way valve connection in some occasions and are widely used. To realize the adjustment of pressure, flow, temperature, liquid level and other parameters, the valve core is subject to cylinder thin-wall window, and the side guide of valve core, which has the characteristics of good stability, difficulty in producing vibration, low noise, large allowable pressure difference, simple connection, etc.

Product Features

The three-way shunt and confluence control valve is characterized by sensitiveaction, simple connection, large fow, small volume and high regulating accuracy.The three-way confuence regulating valve is mainly used to mix two kinds of fluidsinto the third one; the three-way shunt regulating valve is mainly used to divide onefuid into two streams. The three-way shunt and confuence control valve productscan replace two sets of single and double seat control valves which are mutuallyswitched and can be used for regulating and controlling liquid, gas, steam andother media.

Specification Applications

Three-way shunt and confluence control valves are versatile components in fluid management systems, designed to either divide a single fluid stream into two (shunt) or combine two fluid streams into one (confluence). These valves are integral in various industrial applications, providing efficient and precise control over fluid direction and flow rates.

HVAC Systems

In heating, ventilation, and air conditioning (HVAC) systems, three-way valves regulate temperature by directing hot or cold water flow, ensuring optimal climate control. They facilitate the mixing or diverting of water to maintain desired environmental conditions.

Chemical Processing

Within chemical processing industries, these valves manage the combination or separation of chemical streams, enabling precise control over reaction processes and product formulations. Their ability to handle multiple flow paths enhances operational flexibility.

Petroleum Industry

In the petroleum sector, three-way control valves are employed in fluid temperature control systems of heat exchangers, aiding in the efficient management of heating or cooling processes essential for refining operations.

Power Generation

Power plants utilize these valves to control the flow of steam or water within turbines and boilers, contributing to efficient energy production and system stability. Their role in directing and mixing fluids is crucial for maintaining operational efficiency.

Industrial Automation

In industrial automation, three-way valves are integral for process control, allowing for the automated switching between different fluid sources or destinations, thereby enhancing system responsiveness and productivity.
