cryogenic valves
3 in-depth engineering guides on cryogenic valves — specification, selection, testing and procurement.
Everything on cryogenic valves
Vajra's engineering team has published 3 technical guides covering cryogenic valves for industrial valve selection, specification, testing and procurement. Browse the full set below.
Cryogenic Valve Testing per BS 6364 - Test Procedure and Acceptance Criteria
BS 6364 requires cryogenic valves to pass shell, seat, and operational tests at −196°C liquid nitrogen - this guide explains the test sequence, acceptance criteria, and extended bonnet specifications.
Cryogenic Valve Selection Guide for LNG & Low-Temperature Service | BS 6364 | Vajra
Cryogenic valve selection requires extended bonnet design, low-temperature impact tested materials, and special packing arrangements to prevent valve seizure and leakage at −46°C to −196°C service.
How to Select Valves for Cryogenic Service - LNG, LN₂, LOX, LCO₂
Cryogenic service - handling fluids below −46°C - imposes special demands on valves: materials must retain ductility at extreme cold, frost formation must not seize the stem, and the operator's hand must be kept clear of the cold surface. This guide covers everything needed to specify a valve for LNG, liquid nitrogen, LOX, liquid CO₂, and other cryogenic services.
