3 & 4 port rotor mixing valves
IVAR 3 and 4 port mixing valves are designed for mixing and distributing water within heating and cooling systems. Their rotary design provides a 90-degree operating stroke and the valves can be adjusted manually or automatically using a suitable motorised actuator.
The valve body and rotor are manufactured in brass. Compared with traditional cast-iron rotor valves, this construction helps reduce the risk of the rotor and body seizing after periods of inactivity while providing a more compact and lightweight valve.
Choosing between a 3 port and 4 port mixing valve
3 port mixing valves
A 3 port rotor mixing valve can be used for standard mixing and distribution applications. It can also operate as a diverter valve where required by the system design.
4 port mixing valves
A 4 port rotor mixing valve provides mixing on both the flow and return sides. This can be useful where management of the return temperature forms part of the heating-system design.
Manual or motorised control
IVAR rotor mixing valves can be manually adjusted or fitted with a motor for automatic control. The available M 106 motor options include 230 V 3-point regulation and 24 V proportional 0-10 V control.
IVAR mixing valve options
Both the 3 port and 4 port ranges are available in several connection sizes and flow coefficients, allowing the valve to be selected according to the hydraulic requirements of the system.
3 Port Rotor Mixing Valves
3-way rotor mixing valves with lateral mixing, available from 3/4″ to 2″ with a choice of Kv values from 4 to 44.
4 Port Rotor Mixing Valves
4-way rotor mixing valves available from 3/4″ to 2″, with multiple Kv options from 4 to 44 for different system flow requirements.
Motorised Heads
M 106 motors for IVAR rotor mixing valves, including 230 V 3-point regulation and 24 V proportional 0-10 V control options.
Designed for heating and cooling systems
IVAR rotor mixing valves are rated for a maximum operating temperature of 120°C and maximum operating pressure of 10 bar. Multiple Kv values are available within several connection sizes, helping designers and installers select the valve to suit the required system flow characteristics.
Full dimensions, hydraulic characteristics, installation guidance and individual product codes are available from the technical information on the relevant product pages.
3 & 4 port mixing valve FAQs
What is a 3 port mixing valve used for?
A 3 port mixing valve can be used to mix or distribute flow within a heating or cooling system. IVAR’s 3-way rotor valves can also be used as diverter valves where required by the system design.
What is the difference between a 3 port and 4 port mixing valve?
A 3 port valve is typically used for mixing or diverting flow. A 4 port valve can provide mixing on both the flow and return sides of a heating circuit, making it suitable for system designs where return-water temperature also needs to be managed.
Can IVAR mixing valves be motorised?
Yes. IVAR rotor mixing valves can be manually controlled or used with a suitable motorised actuator. IVAR M 106 motorised heads are available with different control options.
