Cryogenic Valves
Cryogenic Tank & Storage Valves
Specialized cryogenic globe, manifold, and thermal relief valves designed for LNG, nitrogen, and industrial gas storage tank installations.
OVERVIEW
Cryogenic Storage Tank Flow Control & Safety
Our cryogenic tank valves are specifically engineered for liquid gas storage and transport vessels. Featuring extended bonnets to clear tank insulation jackets and protect stem seals down to -196°C, the range includes shut-off globe valves, dual-diverter manifold blocks, and compact thermal expansion relief valves to ensure continuous, failsafe operation and overpressure protection.
Key Features
- ✔️ Optimized for Cryogenic Storage - Designed for LNG, LOX, LIN, LAR, and other cryogenic storage tanks
- ✔️ Extended Bonnet Construction - Minimizes heat transfer and protects stem sealing at ultra-low temperatures
- ✔️ Leak-Tight Performance - Provides reliable sealing to prevent cryogenic media loss
- ✔️ Corrosion-Resistant Materials - Manufactured from stainless steel and cryogenic-grade materials for long service life
- ✔️ Safe & Reliable Operation - Ensures dependable isolation and flow control in cryogenic tank and storage systems
