A pneumatically actuated bellows-sealed valve used to control process gas or vacuum-compatible flow paths.
Bellows-sealed valves reduce leak risk and contamination, which is critical in high-purity gas and vacuum service.
High-purity gas/vacuum valves are commonly stainless steel when specified by valve series or VCR fittings.
A welded metal bellows separates the process path from the actuator mechanism.
Air pressure opens or closes the valve through an actuator.
