Top Entry, Extended Bonnet
Cryogenic Ball Valve
Reliable sealing down to -196°C for LNG and cryogenic applications
Specially engineered for cryogenic service with an extended bonnet to keep the stem packing away from the cold zone. The top-entry design allows inline maintenance without removing the valve body from the pipeline. All materials are impact-tested to ensure toughness at cryogenic temperatures.
