Standard Components
• 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.
Operations
The Watts Flood Protection Shutdown Valve system
prevents catastrophic property damage that can oc-
cur due to Relief Valve discharge and/or a blocked or
overwhelmed floor drain during normal relief valve op-
eration. 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 113-12RFP Flood Protection Shutdown
Valve is a normally open valve designed to be installed
upstream 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
manually 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
discharge. 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 elec-
trical service 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.
