Liquefied gas valve

What are Liquefied Gas Valves?

Liquefied gas valves are designed for handling liquefied petroleum gas (LPG), liquefied natural gas (LNG), and other cryogenic fluids. These valves feature extended bonnets to keep the packing gland away from cold media, preventing packing freeze-up.
