Fugitive Emission Bonnet

Sealing arrangement

• Secondary HermetiX or High temperature graphite

Any media that might breach the valve stem seal

• is contained within the device bonnet until valve maintenance can be safely held

The bonnet design allows a sensing device to be fitted

• between the two sealing arrangements, allow immediate breach identification or alerting

A machined lip on the bonnet bottom plane ensures a safe fit over the valve ISO pad

• A static seal provides sealing to the atmosphere

Double blowout proof stems

Linear alignment between valve stem, extension and actuator to reduce side load
