Non-return valves
The EA-RV284 anti-contamination check valve is used as class EA protection according to PN-EN 1717 against reverse flow. 1. It is installed in drinking water installations in places exposed to contact with fluid classified into category 2. It can be used as the main protection at the installation connection to the water supply network, mounted directly behind the water meter. 2. Anti-contamination check valves should also be used on the stub pipe where we fill (add) water to the central heating installation
In the anti-contamination valves category, we offer high-quality HONEYWELL products, available in sizes from 15 mm (1/2 inch) to 50 mm (2 inch). These valves ensure safe water flow, protect the installation against the return of contaminants and contamination of utility water, which is crucial in heating and water supply systems.
