Feature:

The extended bonnet is designed at an appropriate height to keep the stuffing box away from cryogenic surfaces, preventing seal failures caused by low temperatures.

Choosing the right materials and conducting thorough testing are fundamental to ensuring the reliable performance of cryogenic valves, especially for service temperatures as low as -196°C.

A range of trim options is available to suit various process applications.
