Cryogenic Short Stem Globe Valve

Cryogenic Short Stem Globe Valve – Compact Design for Insulated Piping

Cryogenic short stem globe valves utilize reduced bonnet extension (100-200mm) compared to long stem designs, offering installation height savings for cryogenic applications where external vacuum-jacketed piping insulation provides thermal protection preventing packing zone freeze-up. This compact configuration suits African industrial gas facilities, small-scale LNG plants, and cryogenic storage systems where standard long stem valves create excessive vertical clearance requirements in multi-level piping racks.

The short stem design relies on external insulation maintaining packing temperature above freezing rather than extended bonnet length alone. Proper installation with insulation overlap onto bonnet flange ensures thermal protection while reducing valve weight and height compared to long stem alternatives—advantages for African facilities with space constraints or weight-limited structures.
