Fugitive Emission bonnet (FE).

The FE bonnet is an extended spindle equipped with a leak chamber and detection to capture any leaks through the valve spindle seal. This accessory forms an additional seal, providing maximum integrity and safety within systems. The FE bonnet is commonly used for hazardous and/or toxic media.

The FE bonnet can be extended with a purge connection, a media containment unit (MCU) an extended bonnet (XXT) or a pressure box sealing where a pressure chamber is formed between the valve stem seal and the top seal of the FE bonnet.
