VB Exhaust Valves

    • Product Details


      A range of high quality valves for supply and exhaust applications for commercial and industrial projects. Series V valves are best applied to air distribution systems handling relatively low air flow rates within small circular ductwork. The valves provide high initial resistance with wide throttling capability which is necessary to offset the relatively high system resistances.

      VB valves are constructed from steel spinnings protected by a polyester powder gloss white finish. Flanges are fitted with sealing gaskets and all units are supplied as standard with plated steel mounting subframes.
