2. Cryogenic Globe Valve: Material Composition & Key Specifications
Cryogenic globe valves operate at temperatures as low as -196°C, where standard materials become brittle and standard sealing systems fail due to thermal contraction. Our cryogenic globe valves are specifically engineered for these extreme conditions with design features validated by BS 6364 and ISO 28921-1.
Key Design Features for -196°C Service:
Extended Bonnet with Drip Plate: The bonnet is extended to ensure the packing area (stem seals) stays at a temperature above freezing, preventing ice formation and maintaining seal integrity. This is a mandatory design feature per BS 6364 for valves with service temperatures ≤ -101°C . The drip plate prevents condensed moisture from dripping onto insulation.
Deep Cryogenic Treatment: All pressure-containing parts (body, bonnet, disc, stem) are subjected to deep cryogenic treatment at -196°C for minimum 8 hours (or multiple cycles) to transform retained austenite, relieve residual stresses, and ensure dimensional stability at service temperature.
Bolted Bonnet Construction: Per BS 6364 and API 623 requirements, cryogenic globe valves feature bolted bonnet construction for reliable sealing and ease of maintenance. Metal gaskets or spiral wound gaskets provide fire-safe sealing.
