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 (shutting off, pressure regulation, non-return action, etc.) depends on the specific type - a detailed description of the function can be found above for this product.
• Must installation be carried out by a professional? A handy homeowner can install simpler shut-off fittings; for regulating and safety fittings (safety valves, pressure-reducing valves) we always recommend a professional, since these are components with a safety function.
