Fugitive Emission Bonnets (FE) UK & Ireland

Fugitive Emission Bonnets (FE)

Eliminating product emissions is one of the most serious challenges for the process industry and consequently can be the most costly to control. As part of its Health & Safety initiative, Habonim has additional security for the valve stem design for critical applications.

Modular design uses a double defence sealing concept. The first defence line is based on the valve stem seal arrangement, while the second line is integral with the Fugitive Bonnet.

Product Benefits

Additional options

Media Containment Unit (MCU)

Suitable for critical applications when:
Valve stem maintenance needs to be programmed
A combination of high temperature and high cycle conditions
Valve is in low-temperature applications (down to -70 °C / -57 °F)

Caution!: MCU is not to be used with toxic media

Extended Bonnet (EXT)

When valves and pipelines need to be insulated
When valve operation must be elevated from extreme temperature areas
When direct mounting of an actuator to a valve is not suitable

Technical Data

A machined lip on the bonnet bottom plane will ensure a safe fit over the valve ISO pad. A static seal will provide security to the atmosphere.
The bonnet design allows a sensing device to be fitted between the two sealing arrangements. In case of first defence line failure, an alert can be immediately identified.
Any media is contained within the FE bonnet until valve maintenance can be safely carried out.
Double blowout proof stems.
Linear alignment between valve stem, extension and actuator to reduce side load.
Rigid construction.
Precision stem and packing bore finish.
Fire-safe valve stem packing and valve connection to bonnet (upon request)
Stainless steel cast CF8M housing material as standard.
Exotic materials Alloy-20, Hastelloy-C22. Monel and more (upon request).
Various solutions are offered by Habonim when sizing FE bonnets to customer applications: HC (high cycle), N (Control valves), KG (fire-safe and thermal applications), and the HermetiX Habonim patented stem packing.
