The valve serves as a non-slam check valve as needed for zoned pumping, parallel and standby pumping, and condenser water applications. The spring-loaded disk prevents valve chatter and assures positive shutoff. Bell & Gossett's Triple Duty Valve has a calibrated nameplate for rough system balance. The Triple Duty Valve is also equipped with Model RV-125A brass readout valves for more accurate system balance. The calibrated nameplate allows the valve to be returned to the original balance position after shutoff. To repack under system pressure, turn the valve stem to the fully open position. Turning the valve stem to the closed position provides shutoff.
