Bellows Seal (Option D) Spirax Sarco

Possible Applications

This bellows seal option is deployed in industrial processes handling aggressive, toxic, or high-purity media where fugitive emissions must be strictly prevented to ensure environmental compliance and site safety. It is integrated into control valve assemblies operating within chemical synthesis units, pharmaceutical manufacturing lines, and power plant steam loops to isolate the process fluid from the external actuator environment. By creating a hermetic metallic barrier around the valve stem, the equipment prevents costly product loss and eliminates leakage risks associated with thermal cycling and continuous mechanical actuation.
