DN15 PN40 Swing Type Non Return Valve - Stainless Steel Cryogenic Check Valve for LNG Applications
The DN15 PN40 Swing Type Non-Return Valve is a high-performance cryogenic check valve specifically engineered for LNG applications. This horizontal swing type check valve features a disc-shaped valve that rotates around the seat channel axis, providing superior flow control and backflow prevention in demanding industrial environments.
Features a disc-shaped valve with streamlined internal channels that minimize flow resistance, making it ideal for low flow rates and irregular flow conditions.
Specifically designed for LNG applications with excellent performance in cryogenic temperatures down to -196°C.
Manufactured from high-quality stainless steel with precision engineering for long-term reliability.
Effectively prevents hydraulic shock when media stops flowing or reverses direction, protecting your pipeline system.
