3 Way Converging and Diverging Control Valve
A 3 Way Converging and Diverging Control Valve is a specialized control valve designed to regulate and direct process flow through three connected ports. It is widely used in process industries where precise mixing, splitting, diverting, or temperature control of fluids is required.
We supply 3 Way Converging and Diverging Control Valves for industrial applications including oil & gas, petrochemical, chemical processing, power generation, HVAC, water treatment, and general process industries.
These valves can be configured according to process requirements, including valve size, pressure class, body material, trim material, actuator type, flow characteristic, and control signal.
What Is a 3 Way Control Valve?
A 3 Way Control Valve has three ports and is designed to control the flow of a process medium between them. Depending on the internal valve configuration, the valve can perform either a converging or diverging function.
The valve is commonly used where two streams need to be combined or one stream needs to be divided into two separate flow paths.
3 Way Converging Control Valve
A 3 Way Converging Control Valve combines two inlet streams into one controlled outlet.
Typical flow arrangement:
A + B → AB
This configuration is often used for:
- Temperature control
- Fluid mixing
- Heating systems
- Cooling systems
- Process blending
- Steam and water mixing
- Heat exchanger applications
3 Way Diverging Control Valve
A 3 Way Diverging Control Valve divides one inlet stream into two controlled outlets.
Typical flow arrangement:
AB → A + B
Diverging control valves are commonly used for:
- Flow distribution
- Bypass systems
- Heating circuits
- Cooling circuits
- Process diversion
- Heat exchanger bypass applications

- Valve Positioner
- I/P Converter
- Solenoid Valve
- Air Filter Regulator
- Limit Switches
- Position Transmitter
- Booster Relay
The actuator can be selected according to required torque/thrust, operating pressure, fail position, and valve travel.
Electric 3 Way Control Valve
Electric actuators can be used where electrical operation is preferred or where compressed air is not readily available.
Electric control valve assemblies can be configured with suitable:
- Electric Actuator
- Position Feedback
- Control Module
- Limit Switches
- Manual Override
3 Way Control Valve Applications
HVAC Systems
3-way control valves are widely used in heating and cooling systems for regulating water flow and maintaining temperature.
Heat Exchangers
A three-way valve can control flow through or around a heat exchanger to maintain the required process temperature.
Chemical Processing
Suitable valve configurations can be used for controlled mixing and distribution of compatible chemical fluids.
Petrochemical Industry
3-way control valves can be used for process temperature control, flow distribution, blending, and bypass applications.
Oil & Gas
Depending on the process service, 3-way valves can be used for flow diversion, mixing, bypass, and utility systems.
Power Plants
Applications can include cooling water, feedwater-related auxiliary systems, steam services, and other suitable process or utility applications.
3 Way Control Valve for Temperature Control
One of the most common applications of a 3 Way Control Valve is temperature regulation.
A temperature controller measures the process temperature and sends a control signal to the valve positioner. The actuator then changes the valve position, adjusting the flow through the appropriate ports.
This allows the control system to maintain the desired process temperature.
Mixing Application
In a mixing application, the valve combines two streams with different temperatures or flow conditions.
For example:
Hot Stream + Cold Stream → Controlled Mixed Stream
The valve position changes according to the controller output.
Diverting Application
In a diverting application, one incoming stream is divided between two outlet paths.
For example:
Inlet Stream → Process Line + Bypass Line
The valve controls how much flow passes through each outlet.
Advantages of 3 Way Converging and Diverging Control Valves
Precise Flow Regulation
The valve provides controlled distribution or combination of process flow.
Compact Process Arrangement
A single three-way valve can perform flow functions that might otherwise require multiple valves.
Temperature Control
Suitable configurations can help maintain process temperature in heating and cooling systems.
Mixing and Diverting
The same basic valve concept can be used for either converging or diverging applications, depending on the design.
Automated Operation
The valve can be operated using pneumatic or electric actuators and integrated into automatic control systems.
