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, backflow prevention, etc.) depends on the specific type - a detailed description of its function can be found above for this product.
- Does installation have to be done by a professional? A simple shut-off fitting can be installed by a home handyman, but for control and safety fittings (safety valves, pressure-reducing valves) we always recommend a professional, since these are safety-critical components.

Plánujem použiť tento spätný ventil na hlavnom rozvodnom potrubí 3" pre kotolňu s dvoma kazetovými kotlami. Postačí hodnota Kv 28,00 pri prietoku okolo 6 m³/h, alebo by som mal siahnuť po niečom s vyšším Kv?

Pri prietoku 6 m³/h na potrubí DN80 je Kv 28,00 celkom v poriadku, tlaková strata bude nízka a ventil by nemal byť žiadna prekážka v sústave. Ide o ťažký typ, takže je robustnejší a hodí sa práve do kotolní, kde sa čaká dlhodobá spoľahlivosť. Ak by ste neskôr uvažovali o zvýšení prietoku, vtedy by stálo za to prepočítať znovu.
