ESBE VRG Mixing & Diverting Valves

ESBE VRG Series Valves

ESBE VRG series valves are high-quality 3-way rotary mixing and diverting valves designed to provide accurate water temperature control and reliable flow management within heating and cooling systems.

These valves are widely used in boiler systems, heat pump installations, underfloor heating manifolds and hydraulic mixing applications.

The ESBE VRG range includes several popular models, including the VRG131, VRG132, VRG133, VRG231 and VRG232, each designed for specific 3-way mixing or diverting functions within heating systems.

At B.E.E. – The SMART Heating Merchant, we supply a range of ESBE VRG mixing and diverting valves suitable for professional heating installations.

Many ESBE VRG valves are compatible with ESBE actuators, allowing either manual or automatic control depending on your system requirements.

Frequently Asked Questions

What is an ESBE VRG valve?

The ESBE VRG series is a range of high-quality 3-way rotary valves designed to mix or divert water within heating and cooling systems. They provide accurate temperature control and efficient flow management, making them suitable for boilers, heat pumps, underfloor heating, buffer tanks and other hydronic heating applications.

What is the difference between a mixing valve and a diverting valve?

A mixing valve blends water from two inlets to achieve a controlled outlet temperature, helping to regulate the temperature supplied to a heating circuit. A diverting valve directs water from one inlet to one of two outlets, allowing the flow to be switched between different circuits. The correct type depends on your heating system and application.

What is the difference between the ESBE VRG131, VRG132 and VRG133?

The ESBE VRG131, VRG132 and VRG133 are all 3-way rotary valves, but they are designed for different applications and connection configurations. While they all provide reliable flow control and temperature regulation, the correct model depends on your system design, installation requirements and pipe connections. If you're unsure which valve is right for your project, our technical team will be happy to help.

Can ESBE VRG valves be used with heat pumps?

Yes. ESBE VRG valves are widely used in both air source and ground source heat pump systems. They help regulate flow temperatures, control heating circuits and improve system efficiency when used with compatible controls and actuators.

Can ESBE valves be fitted with an actuator?

Yes. Most ESBE VRG valves are designed to work with compatible ESBE actuators, allowing automatic control through weather compensation systems, heating controllers or building management systems (BMS). They can also be operated manually where automatic control is not required.

How do I choose the correct ESBE valve?

Choosing the correct ESBE valve depends on several factors, including whether you need a mixing or diverting function, the required flow rate (Kvs value), the pipe connection size and your heating system design. If you're unsure which model is right for your project, we're always happy to help.

What does Kvs mean?

Kvs is a measure of a valve's flow capacity. It indicates the maximum flow of water that can pass through the valve at a specified pressure drop. Selecting the correct Kvs value helps ensure efficient operation, accurate temperature control and good hydraulic performance.

Which heating systems are ESBE VRG valves suitable for?

ESBE VRG valves are commonly used in a wide range of heating and cooling applications, including:

• Air source heat pump systems
• Ground source heat pump systems
• Gas and oil boiler installations
• Biomass heating systems
• Underfloor heating manifolds
• Buffer tank circuits
• Multi-zone heating systems
• Commercial and domestic heating systems

Do I need an actuator with my ESBE valve?

Not always. Many installations use the valve with the supplied manual handle, while others require an actuator for automatic temperature or flow control. The best option depends on your heating controls and the way your system is designed.

ESBE valves are often used in conjunction with heating pump groups for effective system control and distribution.
