Freeze protection valve. Made of brass, male thread 1 1/4" 108701
Protecting the installation from the effects of frost
A freeze protection valve is a key component of a heating installation, especially in systems with heat pumps. Its function is to prevent damage to pipelines and equipment caused by freezing water. It works by slowly draining the medium from the installation when the temperature drops to around 3°C, minimizing the risk of ice crystal formation. This is a simple but extremely effective solution that protects the investment and ensures the continuous operation of the system.
The valve is made of high-quality brass, which guarantees its durability and corrosion resistance. It is designed for use in installations with a maximum working pressure of 10 bar and an operating temperature from 0 to 65°C. Equipped with an EPDM rubber seal, it ensures tightness and reliable operation for a long time. Connection threads with a size of 1 1/4 inch (male thread) allow for easy installation in standard installations.
Why choose this valve?
Automatic protection: The valve operates independently of the electrical power supply, which is particularly important in the event of a power failure.
Minimizing heat loss: Slow draining of the medium reduces heat loss compared to rapid draining of the installation.
Durable construction: The brass body and high-quality seal ensure long-lasting and trouble-free operation.
Versatility: Suitable for use in both new and modernized installations with heat pumps.
Simple installation: The standard 1 1/4 inch thread facilitates integration with the existing heating system.
Remember to install correctly – it is recommended to install two valves: on the supply and return, as close as possible to the heat pump, to ensure optimal protection of the entire system. Do not insulate the valve, as this will hinder the proper operation of the thermostat sensor and may reduce the effectiveness of frost protection. If necessary, replacement parts (thermostatic insert or vacuum breaker) are available from the manufacturer CALEFFI.
- The protection works in the event of power failure to the pump.
- Antifreeze valve, installed in a system with a heat pump, allows a slow bleeding when the medium temperature drops below 3 ° C. This prevents the formation of ice in the installation, protecting its components from damage.
