Frequently Asked Questions
What is a Reduced Port Design and why does it matter?
+
A Reduced Port Design features a smaller bore diameter compared to the pipe, which minimizes turbulence and pressure drop across the valve. This makes it especially suitable for flow-sensitive applications where consistent flow control is critical.
What does DBB (Double Block and Bleed) technology mean?
+
DBB stands for Double Block and Bleed. This design provides two seating surfaces that block fluid from both directions, while a bleed port in between allows operators to verify sealing integrity and safely vent trapped pressure, ensuring superior safety and leak prevention in critical systems.
What advantages does Trunnion-Mounted Forged Construction offer?
+
Trunnion-mounted construction fixes the ball in place with mechanical support at the top and bottom, reducing operating torque and wear. Combined with forged construction, this design delivers superior structural integrity and durability, especially in high-pressure and low-temperature environments.
How low a temperature can cryogenic valves reliably operate at?
+
These cryogenic valves are engineered to maintain reliable sealing and full operational performance at temperatures as low as -196°C, making them ideal for liquefied natural gas (LNG), liquid nitrogen, and other cryogenic fluid handling applications.
What materials are available for these valves?
+
The valves are available in a range of high-performance materials including A350 LF2, Inconel 625, Hastelloy C, and other alloys. This variety ensures compatibility with diverse industrial environments, including highly corrosive, high-pressure, and extreme-temperature applications.
What testing procedures do the valves go through before delivery?
+
Every valve undergoes comprehensive in-house cryogenic testing that simulates real-world extreme conditions. This includes pressure testing, seat leakage testing, and full operational testing at cryogenic temperatures to ensure each unit meets the highest standards of consistent and reliable performance before shipment.
