Bellows valve manufacturers
Bellows-sealed valves use a welded metal bellows to isolate the stem from the process medium, preventing leakage to atmosphere and eliminating packing wear. This sealing method is preferred where emissions control, purity, or operator safety are critical. Bellows valves can be manually operated or automated, and are available with globe-style, stop, or stop-check internals depending on flow and control requirements.
These valves are used in steam distribution, reactor systems, high-purity chemical lines, specialty gas service, vacuum systems and applications handling toxic or hazardous media. The bellows construction provides long service life with minimal adjustment, making them suitable for continuous or critical-duty operation.
