Flood Protection Shutdown Control Valve
Series LFF113RFP Flood Protection Shutdown Control Valves prevent catastrophic property damage due to relief valve discharge and/or a blocked or overwhelmed floor drain during normal relief valve operation. The Series LFF113RFP remains fully open under normal conditions. If the RPZ relief valve should open, excess flow through the drain pipe trips the flow sensor which energizes the solenoid and closes the valve. They feature a time delay relay to prevent false alarms and a control valve switch to provide an electronic, visual and audible indication of valve closure.
