Application
The Marine Cryogenic Three-Piece Ball Valve is a specialized fluid control component for marine low-temperature systems, featuring a detachable three-piece structure that allows easy disassembly, maintenance, and replacement of internal parts without removing the entire valve from the pipeline—ideal for confined ship spaces. Crafted from high-quality cryogenic cast steel, it boasts excellent low-temperature toughness, corrosion resistance, and pressure-bearing capacity, with an optimized ball and seat design (often paired with PTFE or metal seals) ensuring reliable sealing and zero leakage even in ultra-low-temperature marine environments (down to -196℃ for LNG applications). Complying with strict marine industry standards, it enables fast on-off control of cryogenic media like LNG, liquefied propane, or low-temperature fuel, offering low flow resistance, long service life, and strong adaptability to high-humidity, salt-laden marine conditions, making it a critical component for marine low-temperature fluid systems.
Packing & Delivery
We use through-hole packaging, and the valve will be wrapped in a PP bag to ensure the safety of the product to the greatest extent. We support shipping by sea and by air, and the products can also be shipped to any port you specify.
