Manufacturing Process of Cryogenic Floating Ball Valve

Material Selection & Certification → Precision Casting / Forging

Heat Treatment → CNC Machining → Ball & Seat Assembly

Cryogenic Cleaning → Assembly with Extended Bonnet

Pressure & Helium Leak Test (ISO 28921-1) → Final Inspection & Marking

Packing & Supply

Material selection ensures the valve body, ball, and stem meet minimum impact values and chemical requirements (see ASTM/EN standards). The precision casting or forging process provides high-density, low-porosity components. Advanced CNC machining ensures critical tolerances (<0.01mm).

All cleaning and assembly are performed in clean rooms to avoid grease and particulate contamination.
Cryogenic valves undergo helium leak testing with maximum leak rates <6×10⁻⁶ mbar·l/s (ISO 28921-1 certified).
Traceable identification (nameplate + unique valve number) is standard for QA.

Expert FAQ: Cryogenic Floating Ball Valve Selection & Use

Q1. What is the best material choice for cryogenic floating ball valve bodies?

A: Stainless steel grades CF8M (A351) and forged steel (F316/F304) are widely preferred for their low-temperature ductility and resistance to embrittlement per ASTM A351 and BS6364 standards.

Q2. Which seat material is most reliable for sealing at -196°C?

A: PCTFE and Devlon seats offer outstanding low-temperature resilience, chemical resistance, and minimal deformation under load. PTFE is acceptable for less harsh duties above -30°C.

Q3. How is the extended bonnet designed to prevent cold transfer?

A: The extended bonnet creates an insulating air column between media and packing. This prevents stem frosting and maintains safe manual or automatic operation per ISO 21011.

Q4. What is the typical leakage class?

A: Class VI (bubble-tight) per ISO 5208 and API 598. Each valve is hydrostatic and helium-leak tested at cryogenic temp for this performance.

Q5. Are these valves suitable for hydrogen and oxygen services?

A: Yes. Low iron and non-wetted components, non-sparking alloys, and degreased solvent-cleaning per ASTM G93 qualify for H₂/O₂ ultra-pure systems.

Q6. What actuation options are supported?

A: ISO 5211 mounting pad for direct interface with pneumatic or electric actuators. Manual lever operation is standard on sizes up to 6".

Q7. How are valves maintained in the field?

A: The modular 2-piece design allows on-site seal/spring change without line removal. Standard repair kits are available.
