Product information:
Special materials of construction such as low temperature alloy steels, austenitic stainless steel, aluminum bronze or Monel are required.
• Function: Ensures unidirectional flow and prevents backflow in cryogenic systems.
• Applications: Ideal for liquefied gases such as LNG, nitrogen, or oxygen.
• Materials: Constructed from stainless steel or high-nickel alloys for thermal resistance and durability.
• Key Features:
• Compact design
• Low leakage rates
• Reliable performance under cryogenic conditions
• Industries: Used in industrial gas, petrochemical, and aerospace sectors.
• Benefits: Safeguards equipment, maintains system integrity, and ensures safe and efficient cryogenic operations.
Structural Features:
• Cryogenic Bonnet: Extends the stem and protects packing from extreme cold.
• Soft Seats: Made of PTFE or similar materials for tight sealing.
• Body Design: Bolted or welded to enhance leak prevention.
• Extended Stems: Minimize impact from thermal flux.
• Spring-Assisted Closure: Ensures prompt and reliable sealing.
• Material Construction: Commonly stainless steel or high-nickel alloys for durability.
• Flow Path: Designed to maintain optimal flow even at low temperatures.
• Compact Design: Helps in reducing the footprint while maintaining performance.
