Frequently asked questions
- How do I choose the correct type and size of fitting/valve? Follow the nominal pressure (PN) and operating temperature (T) stated in the technical parameters - they must match or exceed the actual operating conditions of your system, and the connection size must match the pipe diameter.
- How does this fitting/valve work? The exact operating principle (shutting off, pressure regulation, non-return function, etc.) depends on the specific type - a detailed description of the function can be found above for this product.
- Must installation be done by a professional? Simple shut-off fittings can be installed by a competent DIYer; for control and safety fittings (safety valves, pressure-reducing valves) we always recommend a professional, as these are safety-critical components.

Hi there, I have a wood boiler with a return line that can get quite cold during startup, and I'm looking for a thermostatic bypass valve to protect it from thermal shock. Would this 5/4" valve with the 80°C setting work for that purpose, or is it meant for something else entirely?

This valve is actually designed to open and let water bypass when the temperature reaches 80°C, so it's more of an overheat protection rather than a cold-return protection valve. For protecting a boiler from cold return water, you'd typically want a thermostatic mixing valve set to a lower temperature like 55–60°C. If you're unsure which type fits your setup, feel free to contact us and we can point you in the right direction.
