Frequently Asked Questions

• How do I choose the right 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 (shut-off, pressure regulation, non-return function, etc.) depends on the specific type - you can find a detailed description of the function above for this product.
• Does the installation have to be done by a professional? Simple shut-off fittings can be installed even by a skilled DIYer, but for control and safety fittings (safety valves, pressure reducing valves) we always recommend a professional, as these are components with a safety function.
