Standard Components
Operations
The Watts Flood Protection Shutdown Valve system
prevents catastrophic property damage that can occur
due to Relief Valve discharge and/or a blocked or over-
whelmed floor drain during normal relief valve operation.
Typical conditions which can cause continuous relief
valve discharge are:
• Fouled First Check Seat due to dirt, debris or rocks
• Failed First Check Spring
• Clogged or blocked Relief Valve Sensing Line
• Relief Valve Diaphragm failure
The Watts 113-6RFP Flood Protection Shutdown Valve
is a normally open valve designed to be installed up-
stream of a Reduced Pressure Zone (RPZ) Backflow
Prevention device. It is normally open and closes drip-
tight when continuous relief valve discharge through the
drain pipe is sensed by the FS99 Flow Sensor, energiz-
ing the Solenoid Pilot. The Solenoid Pilot is equipped with
a Manual Operator which simulates power when manu-
ally engaged. The valve mounted JB113 Junction Box
is equipped with an adjustable time delay to avoid valve
closure due to intermittent or nuisance relief valve dis-
charge. The Limit Switch provides local visual and remote
electrical indication of valve closure. The valve remains
closed and cannot re-open if flow stops or electrical ser-
vice is interrupted, and must be manually reset after the
RPZ is diagnosed and/or repaired.
The valve comes complete with the valve mounted JB113
Junction Box with adjustable time delay, pre-wired So-
lenoid Valve, Manual Reset with Pressure Gauge, Limit
Switch and FS99 Flow Sensor (field installed). Fail-safe
operation is assured by closing valve upon Main Valve or
Pilot Diaphragm failure and a specially coated Main Valve
Stem for added protection.
• Installed upstream of Reduced Pressure Zone Backflow
Preventer.
• Normally Open Valve - Closes when discharge from
RPZ Relief Valve is sensed or by engaging Solenoid
Manual Operator.
• Limit Switch provides local visual and remote electrical
indication of valve closure.
• Valve must be manually reset. Pressure gauge
(provided) indicates valve reset for automatic service.
• Anti-Scale Coated Main Valve Stem for added
protection.
• Fail Safe operation - Valve closes upon Main Valve or
Pilot Diaphragm failure.
