DH‑15A Gas Cylinder Valve

DH‑15A gas cylinder valve is a heavy‑duty cryogenic gas control component suitable for low‑temperature liquefied gas storage cylinders. It supports maintenance matched with cylinder head valve grinding machine, can be fitted with protective cylinder valve guard, works as reliable cylinder gate valve for cryogenic pipeline control, ensures stable cylinder valve gas flow under extreme temperature, and adopts durable cylinder valve gasket for leak‑proof sealing. Each valve undergoes strict low‑temperature and high‑pressure testing, applicable for‑196℃ ~ +60℃ working environment. It features Φ22.5 welding outlet connection and M30×1.5 inlet thread. Bulk wholesale and OEM customization services are available for global buyers.

Full Product Details

DH‑15A gas cylinder valve is professionally engineered for cryogenic liquid gas cylinders. Premium forged brass material delivers outstanding performance under ultra‑low‑temperature and high‑pressure working conditions ranging from ‑196℃ to +60℃. This cryogenic valve cooperates with cylinder head valve grinding machine during overhaul procedures, can install impact‑resistant cylinder valve guard for on‑site protection, functions as heavy‑duty cylinder gate valve to regulate gas flow, guarantees steady cylinder valve gas transmission for LNG, LO2, LN2, LAr media, and relies on high‑quality cylinder valve gasket to prevent medium leakage. Working pressure reaches 3.5MPa with DN16.5 flow passage, outlet adopts Φ22.5 welding connection while inlet thread is M30×1.5, without built‑in safety device. Widely used in cryogenic storage tanks, industrial liquid gas equipment and related export supporting projects. Large‑volume orders, connection adjustment and OEM custom solutions are supported for worldwide purchasers.
