LNG Safety Valve, API 526, A216 WCB, DN50, PN40, 2 Inch, RF

Key Specifications / Features

The Liquefied Natural Gas (LNG) Safety Valve, manufactured per API 526, features a durable ASTM A216 WCB carbon steel body for high-pressure protection. Sized at DN50 (2 inches) and rated for PN40/Class 300 LB, it is equipped with RF flanged ends for secure and leak-proof installation. Engineered for LNG applications, it ensures reliable overpressure protection and system safety.

The Liquefied Natural Gas (LNG) safety valves are designed for use in liquid-phase outlet pipes, with an operational temperature range of -40°C to 80°C. These valves are equipped with a unique mechanism that automatically returns liquefied gas to the gas tank when the inlet and outlet differential pressure exceeds 0.5 MPa, ensuring safety and efficient operation in LNG systems.
