Bell & Gossett has introduced a new Triple Duty® Valve that performs all of the functions of three valves that are normally required on the discharge side of hydronic pump systems. The new Triple Duty Valve includes a calibrated balance valve, a non-slam check valve and a shut-off valve. The calibrated balance valve optimizes system operating efficiency and provides precise flow with a maximum range of control (8-9 turns). The non-slam check valve assures positive shut-off free of water hammer or valve chatter as needed for zoned pumping, parallel and standby pumping, and condenser water applications. The shut-off includes a calibrated nameplate and memory button allowing the entire valve to be returned to its initial balanced position after shut-off. Bell & Gossett.
