Safety valve for electric water heaters AF8, 6.7 bar, G 3/4 inch x Rp 3/4 inch 4223410

Safety valve for electric water heaters – reliable protection of the installation

This safety valve, model AF8, is specifically designed for electric hot water heaters. Its function is to protect the installation from excessive pressure increase, ensuring safe and efficient system operation. The design combines a safety valve, check valve and drain valve, creating a comprehensive solution for tank protection.

This valve is particularly useful in situations where the pressure in the heater rises above the permissible value – then the water outlet opens automatically to the outside, reducing the pressure. Additionally, the check valve prevents water from flowing back from the installation into the heater when the network pressure drops, and the drain valve allows the pressure in the tank to be reduced.

Construction and application

The AF8 valve has G¾" x Rp¾" connections, making it compatible with most standard installations. Made of brass, it guarantees durability and corrosion resistance. It is an essential element in every hot water system with an electric heater, mounted directly on the cold water supply near the device. This ensures effective protection against potential failures and damage caused by excessive pressure.

The application of this valve is wide – from domestic installations to systems in multi-family buildings. Its compact size (height 70 mm) makes it easy to install even in tight spaces. The valve is designed for continuous operation and is intended to protect electric hot water heaters, where the opening pressure is 6.7 bar.
