Home > Product > Ball Valve > Ball valves Based on Pressure Rating
At Perfect Engineers, we offer a wide range of pressure-rated ball valves that are built to handle everything from low-pressure water lines to ultra-high-pressure steam and gas systems. Whether you’re designing a simple irrigation line or an API-grade oil refinery pipeline, selecting the correct pressure class is crucial for both safety and performance.
This guide will help you understand how ball valve pressure ratings are categorized, and how to select the right one for your system.
A ball valve’s pressure rating indicates the maximum pressure it can safely withstand at a specific temperature. It’s defined by international standards like ANSI/ASME, DIN (PN rating), and others.
Pressure rating depends on:

Yes—higher pressure valves are backward compatible, but they cost more.
Not recommended above 10 bar. Use SS or Brass for safety.
RPTFE or graphite seats are best for steam above 150°C.
Yes. All valves undergo hydrostatic and pneumatic testing as per API 598 or EN 12266.
