981GD

Ductile Iron Single Chamber Pump Control Valve with Pressure Reducing Feature

981GD (Globe) and 981AD (Angle) Series is designed to minimize the surges associated with the starting and stopping of pumps, and automatically reduce pump outlet pressure to a constant lower downstream pressure regardless of varying flow rates. The valve opens at an adjustable rate upon pump start-up, and closes at an adjustable rate upon pump shut-off. When the valve is near closed the limit switch is tripped, turning the pump off. The pump starts and stops against a closed valve. The Solenoid Pilot has provisions for manual operation in the event of power outage.
