EURA check valves - heavy

This category includes heavy-duty check valves from the EURA series, designed for use in heating and plumbing systems. These valves are manufactured from brass CW617N and feature a polymer screen for filtration. They operate at a maximum temperature of 90°C and are suitable for applications where backflow prevention is critical, such as in circulation pump lines or closed-loop heating systems. The valves are available in a range of sizes from 1/2" to 4" with internal FF (female flange) connections.

Each model is tested for drinking water compatibility (ATEST certified) and is engineered to open at a minimum differential pressure of 0.02 bar. They are ideal for use in systems with low-pressure differentials and require minimal maintenance due to their robust construction and self-closing mechanism.

How to choose

• Match the valve size to the pipe diameter and flow requirements using the Kv values provided (e.g., 1.50 to 56.00) to ensure correct flow capacity.
• Select the appropriate internal FF connection type to match the system’s flange design and ensure compatibility with pump or pipe fittings.
• Verify the operating temperature does not exceed +90°C and that the system pressure is within the PN15 rating.
• Confirm the valve is suitable for the fluid type, particularly if used in drinking water systems (ATEST certified models are available).
