Forged steel cryogenic gate valve

产品概览

Our DN15-DN50 forged steel cryogenic gate valve is engineered for precision flow control in small-scale LNG, laboratory gas, and compact cryogenic systems. Manufactured from ASTM A350 LF2 forged steel with extended cryogenic bonnet design, it ensures bubble-tight shutoff at temperatures down to -196°C (-320°F).

主要功能

1. Precision Compact Design

• Space-saving forged steel body optimized for DN15-DN50 pipelines
• API 598 Class VI sealing with lapped seat surfaces
• Low-profile flange design (EN 1092-1 compliant)

2. Certified Cryogenic Performance

• Extended bonnet (200mm standard) prevents stem freezing
• Deep cryogenic treatment with liquid nitrogen stabilization
• Vacuum jacketing option for ultra-low temp insulation

3. Superior Forged Steel Construction

• ASTM A350 LF2 forged body (SS304/316 stem optional)
• STL hard-faced seats for extended service life
• Fire-safe design compliant with API 607/6FA
