Triple Duty Valve
Straight Pattern with Soft Seat Nonslam Check Valve,
Throttling Valve, Calibrated Balance Valve and Shutoff Valve
DESCRIPTION
The Triple Duty Valve is a quiet operating heavy-duty valve which
performs all of the functions normally required on the discharge side
of hydronic system pumps.
The valve serves as a nonslam check valve as needed for zoned
pumping, parallel and standby pumping, and condenser wate
r
applications. The spring loaded disk prevents valve chatter, and
assures positive shutoff.
Bell & Gossett's Triple Duty Valve has a calibrated nameplate fo
r
rough system balance. The Triple Duty Valve is also equipped with
Model RV-125A 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.
