Product Features

1. Conforms to American standards: Strictly designed and manufactured according to American standards such as API 600, API 602, or ASME B16.34, with flange dimensions and pressure ratings conforming to ASME B16.5 / B16.47.

2. Extended bonnet (long-neck design): An extended bonnet of standard length is adopted to keep the packing box away from the ultra-low temperature medium, ensuring the packing works at ambient temperature and preventing sealing failure caused by freezing.

3. High-quality cryogenic materials: The body and internals can be made of low-temperature carbon steel such as LCB, LC3, or stainless steel such as CF8M, maintaining excellent impact toughness at extremely low temperatures from -46°C to -196°C to prevent brittle fracture.

4. Anti-frost drip plate design: A drip plate is provided at the extended bonnet to prevent condensed moisture in the air from freezing and flowing down the body, while also facilitating the installation of external insulation layers (such as PUF/perlite).

5. Comprehensive safety protection: Equipped with an anti-blow-out stem structure, anti-static device, and fire-safe structure design to ensure the safety of cryogenic flammable and explosive media.

6. Backseat structure: The valve stem is equipped with a backseat structure, allowing online packing replacement without shutting down the system when the valve is fully open.
