Use these control valves in cryogenic plants
Series 4000 control valves (photo) are designed for super-vacuum-insulated cryogenic plants, and can also be used in pilot or experimental plants. These valves are machined from stainless steel, and are rated for temperatures from –196 to 100°C. Internal parts can be removed or replaced without the need to remove the valve body from the pipeline, simplifying maintenance operations. Handwheel functionality is included for emergency operation.
