Rotary valve (definition)

Rotary valve — is a shut-off and control device used in heating systems to control the flow of coolant. It works by rotating a disk or ball around its axis, which opens or closes the passage for the liquid. In the context of heating systems, especially when using a single heat source for several circuits, rotary valves play an important role in ensuring accurate distribution thermal energy.

Rotary valve: features of rotary valve installation

1. Separation of contours:
   • Flow regulation: Rotary valves allow precise regulation of the coolant flow between different circuits of the heating system. This is especially important when connecting high-temperature and low-temperature circuits (e.g. radiators and heated floors) to one heat source.
   • Load management: Using rotary valves, you can direct the required amount of heat to each circuit, ensuring uniform heating of all zones and preventing overheating or underheating of individual areas.
2. Compatibility with automation:
   • Connection to control systems: Rotary valves can be equipped with electric drives, which allows them to be integrated into automated heating control systems. This allows centralized control and regulation of temperature in different zones.
   • Reaction to changing conditions: Thanks to automatic control systems, rotary valves can quickly respond to changing conditions (for example, a drop or increase in outside temperature) and redirect the flow of coolant to the appropriate circuits.
3. Installation and operation:
   • Easy to install: Rotary valves are usually compact in size and simple in design, which makes them easy to install in heating systems. They can be installed in horizontal and vertical sections of pipelines.
   • Reliability and durability: Such valves are made from materials resistant to corrosion and high temperatures, which ensures their durability and reliable operation in heating systems.
4. Energy efficiency:
   • Optimization of heat consumption: The rotary valve helps to optimize the distribution of thermal energy, which helps to reduce energy costs. They allow you to supply heat in exactly the quantities necessary to maintain a comfortable temperature in each zone.
   • Minimizing heat loss: Due to precise regulation of coolant flows and control of heat distribution in circuits, the heating system operates more efficiently, which reduces overall heat loss and increases the energy efficiency of the system.
5. Flexibility of the heating system:
   • Modularity: Rotary valves facilitate the integration of new circuits into an existing heating system. This is especially important when upgrading the system or connecting additional heating devices.
   • Multifunctionality: Depending on the design and materials, rotary valves can be used for various types of heat carriers, including water and antifreeze liquids, which makes them universal for use in various heating systems.

A rotary valve is an important component in heating systems, especially when it comes to distributing heat from one source to several circuits. Their correct installation and use ensure efficient and economical distribution of thermal energy, increasing the comfort and reliability of the entire heating system.
