Cryogenic Valves
Cryogenic Side-Entry Triple-Offset Butterfly Valves
High-pressure Class 1500 side-entry triple-offset butterfly valves featuring an in-line replaceable seat design for cryogenic services down to -196°C.
OVERVIEW
In-Line Maintainable Cryogenic Isolation
Our cryogenic side-entry triple-offset butterfly valves represent the pinnacle of high-performance flow isolation for low-temperature and high-pressure services. Engineered with a side-entry retainer ring, these valves allow for the maintenance and replacement of the seat and laminated seal ring directly in the pipeline, minimizing downtime. Combining triple-offset frictionless rotation with an extended gas column bonnet, they deliver bubble-tight bi-directional shut-off at class 1500 pressures.
Key Features
- ✔️ Triple-Offset Sealing Design - Provides bubble-tight shut-off with minimal seat wear
- ✔️ Side-Entry Construction - Enables easy maintenance and extended service life
- ✔️ Cryogenic Temperature Rated - Engineered for reliable operation in ultra-low temperature environments
- ✔️ Low Torque Operation - Quarter-turn design ensures smooth and efficient valve actuation
- ✔️ Ideal for LNG & Industrial Gases - Suitable for LNG, LOX, LIN, LAR, LPG, and other cryogenic applications
