Check valves EURA - SPRINT

The Return Valves EURA - SPRINT category includes threaded check valves designed for use in heating, plumbing, and pump systems. These valves prevent reverse flow in closed circuits and are suitable for installation in circulation pumps, expansion vessels, and heat exchangers. They operate at a maximum temperature of +150 °C and are constructed from nickel-plated brass (CW617N), ensuring corrosion resistance and durability in wet environments.

Available in sizes from 1/2" to 4" with internal threads (FF), these valves are sized according to the flow coefficient (Kv) values ranging from 2.00 to 264.00. They are ideal for use in low-pressure systems and are compatible with standard heating system configurations.

How to choose

• Select the appropriate size based on the flow requirements of the system, using the Kv value to match the expected flow rate.
• Ensure the valve has the correct internal thread (FF) to match the pipe or fitting in the installation.
• Verify that the material (nickel-plated brass) is compatible with the system’s fluid and operating conditions.
• Confirm the maximum operating temperature of +150 °C is suitable for the intended application.
• Check the PN rating (PN 4) to ensure compatibility with low-pressure systems.

Frequently asked questions

What is the maximum operating temperature of these valves?
These valves are rated for a maximum temperature of +150 °C, making them suitable for use in heating and hot water systems.

Can these valves be used in high-pressure systems?
No, these valves are designed for low-pressure applications with a PN rating of 4. They are not suitable for high-pressure systems.

Are these valves compatible with copper or steel piping?
Yes, the nickel-plated brass construction is compatible with both copper and steel piping, provided the system fluid is non-corrosive.
