You’ve probably heard about high-temperature or cryogenic valves, the ones that are incredibly resistant because they operate under extreme conditions. But what makes them so special? And how do you know if they’re the right fit for your needs? Stick around, and I’ll explain it all.

Before diving in, here’s a quick 3-minute video where I break down how these valves work and why they are the perfect solution for such demanding environments:

What Are High-Temperature or Cryogenic Service Valves?

To put it in simple terms, these are needle valves, meaning they are designed to precisely regulate flow in a process. However, they feature a special design that allows them to operate under either extremely high or extremely low temperatures.

And you might be wondering, “What makes this design so special?” Don’t worry—we’ve got you covered! Keep reading, and we’ll clear up that doubt in no time.

What Makes High-Temperature Valves Special?

When things start heating up—literally—our high-temperature valves are the ideal choice, thanks to:

  • Smart design: Featuring an extended stem with finned construction that dissipates heat before it reaches the packing, protecting it and ensuring long-term optimal performance.
  • Top-quality materials:
    • 316 stainless steel as standard: Perfect for temperatures up to 450°C.
    • 321 stainless steel: Built for even more extreme conditions, handling up to 800°C thanks to its titanium-enhanced resistance.

And What About Cryogenic Valves? What Makes Them So Special?

When temperatures drop to extreme lows, our cryogenic valves keep everything under control effortlessly:

  • Extreme operating range: Designed to function from -268.9°C—yes, almost absolute zero—up to 230°C, while handling pressures up to 100 bar.
  • Premium materials: Made from 316/316L stainless steel, ensuring secure sealing, even with fluids like liquid hydrogen or nitrogen.
  • Cryogenic compliance: Certified to BS 6364 and BS EN1626 standards, guaranteeing quality and safety under extreme conditions.

Perfect for applications such as liquefied gas handling and storage.

Total Adaptability for Your Project

Because we know that not all systems are the same, our valves are designed to adapt to your needs:

  • Custom connections: NPT, BSP, SW, or even flanged options available.
  • Special oxygen degreasing: If you’re working with oxygen, our valves comply with ASTM G93, ensuring safe usage.
  • Full customization: We manufacture valves according to your specifications, from dimensions to finishes.

We understand that every project is unique, and every detail matters. That’s why we don’t just sell valves—we customize them to fit your world. Need something tailor-made? Special connections or a specific material? We’re here to make it happen.

Why Choose a Redfluid Valve?

  • Maximum reliability: Designed to withstand extreme conditions, whether high heat or freezing cold.
  • Durable materials: From stainless steels to special alloys, ensuring long lifespan and top performance.
  • Compliance with international standards: ASME, DIN, ISO… We’ve got you covered.
