Metflow Engineers is a premier manufacturer and supplier of stainless steel long stem cryogenic globe valves, engineered to deliver absolute flow regulation and bubble-tight shutoff down to -196°C (-320°F). Cast and forged from specialized low-temperature stainless steel alloys (including ASTM A351 CF8 and CF8M), our cryogenic globe valves feature an extended vertical bonnet columns. This long stem profile establishes a safe thermal barrier that keeps system fluid packing warm enough to prevent destructive icing and packing leakage during liquid gas media containment.
