Cryogenic Steam Jacket Globe Valve

Cryogenic Steam Jacket Globe Valve – Active Heating for Freeze Prevention

Cryogenic steam jacket globe valves incorporate heating jacket around the bonnet, using steam or electric heating to actively maintain packing temperature above freezing in ultra-low temperature service. This active thermal management suits intermittent cryogenic service, cold-box applications, and situations where passive extended bonnet designs cannot maintain adequate thermal gradient—common in African LNG facilities with variable ambient conditions or steam jacket valves providing guaranteed packing operability regardless of process upsets.

The steam jacket creates controlled heat input preventing ice formation during prolonged cryogenic exposure while allowing compact valve construction compared to extended bonnet alternatives. Trace heating systems integrate with African facility utility steam or electric heating circuits, providing reliable anti-freeze protection for critical isolation and control valves in LNG, industrial gas, and petrochemical cryogenic applications.
