204PRV Degassing Relief Valve Applicator

Accraply’s 204 PRV is engineered specifically for the application of pressure relief valves which are used to release the internal build up of pressure in containers or flexible packaging.

With the 204 PRV, all aspects of the valve application are controlled by the integrated microprocessor. This includes oil insertion into the valve, hole punching in the film/container, and precise valve placement over the hole.

This high quality applicator offers the flexibility to be mounted to a variety of bag making machines including continuous or intermittent form, fill and seal machines.
