Description
An extension device to allow a larger distance between the handle or actuator and the valve body. The extension bonnet does not seal at its upper end and is open to the atmosphere.
The valve stem seal is in use for media sealing.
Extended Bonnet
Suitable for critical applications when:
- Valve and pipe lines need to be insulated
- Valve operation must be elevated from extreme temperature areas
- Direct mounting of actuator to a valve is not suitable
Caution!: In any case the vents are sealed – pressure within the FE bonnet must not exceed 50 bar
