Bonnets
The valve bonnet provides a housing and guide for the trim, carries the trim packing and mounts the actuator.
Selection of the bonnet will depend on the type of packing and temperature of the medium. For high temperatures a cooling fin or extended cooling fin bonnet is available. For low temperature cryogenic applications, a 14” extended bonnet will be required. For leak-free pressure or vacuum applications a bellows bonnet is available.
