Stainless Steel Single Chamber Pump Control Valve with Rate-of-Flow Feature

984GS (Globe) and 984AS (Angle) Series is designed to minimize the surges associated with the starting and stopping of pumps, and automatically limit flow rate to a constant, adjustable maximum. 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.


  • Automatically limits flow rate to a constant adjustable maximum
