Everything on BS 6364
Vajra's engineering team has published 5 technical guides covering BS 6364 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.
Cryogenic Valve Selection for LNG, Oxygen and Ethylene Service
Cryogenic valves for LNG, liquid oxygen, liquid nitrogen, and ethylene service must handle temperatures down to -196°C without embrittlement, leakage, or icing of the stem seal. This guide covers cryogenic valve material selection, extended bonnet design rationale, BS 6364 and API 6D cryogenic requirements, and how to specify and source cryogenic valves for LNG terminals and industrial gas plants.
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.
Cryogenic Valve Design and LNG Applications
Cryogenic valves must maintain leak-tight performance from ambient temperature down to -196 degrees C for liquid nitrogen, LNG and LPG service. This guide covers extended-stem design, low-temperature material qualification, standards and testing requirements.
