        Comments about 79, 1/2" x 3/4" Straight Water Main Vent Valve:

        I am an assistant property manager for a building built in 1968. Finding parts for the mechanical equipment for our building can be tough. Pex is a great resource! This valve is exactly what we needed.

          Q:

          We need a product similar to the Hoffman 79 but with a greater pressure rating somewhere in the 150 PSI to 200 PSI range anything available?

            We recommend taking a look at the Hoffman 78, which has a PSI of 150.
