The Riverhawk “Peregrine” bolt tensioning device (PET) is lightweight, compact, and thus flexible in use. If your installation situation provides sufficient thread protrusion, the “Peregrine” bolt tensioning device can be used without any problems. It is one of the smallest and lightest versions in its class.

 

It has a spring return mechanism, which makes operation comfortable. The integrated overload protection ensures a secure connection and prevents leaks. The overload protection value can be determined visually at any time through the practical color coding. The Peregrine bolt tensioning device was developed for the ASME 16.47, ASME 16.5, & API 6A flanges. We can design each of our bolt tensioning devices individually and according to your wishes.
