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 oor 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) Backow
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 ow 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, Limi
Switch and FS99 Flow Sensor (eld installed). Fail-safe
operation is assured by closing valve upon Main Valve o
Pilot Diaphragm failure and a specially coated Main Valve
Stem for added protection.
Installed upstream of Reduced Pressure Zone Backow
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.

JB113 Junction Box
The valve mounted JB113 Junction Box is a lockable NEMA 4 enclosure equipped with an adjustable time delay
electrical relay and terminal strip. There are three 3/4 inch conduit connections. The valve solenoid is prewired.
The valve is normally open and closes drip-tight when continuous relief valve discharge through the drain pipe is
sensed by the FS99 Flow Sensor.
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 time delay is adjusable from 0-30 seconds.
Adjusting the dial clockwise increases the time delay for valve closure. Adjusting the dial counterclockwise de
creases the time delay for valve closure.

Installation
Control Valve
Fully read all technical information provided.
Prior to installation ush line to remove debris. Install valve upstream of the RPZ Backow Assembly.
For ease of valve service and electrical connections do not install valve vertically. Instal
valve horizontally in line (valve cover facing UP), so ow arrow matches ow through the
line. Consult factory prior to ordering if installation requirements are other than described.
Vertical installation of valves larger than 6 is not recommended and may result in poor valve
performance and increased maintenance requirements.
Install inlet and outlet isolation valves. NOTE: When using buttery valves, insure disc does
not contact control valve. Damage or improper valve seating may occur.
Provide adequate clearance for valve servicing and maintenance.
Install pressure gauges to monitor valve inlet and outlet pressure.
Connect cover discharge control tubing to oor drain. Consult Valve Cover Capacity charon page 2 to determine volume of cover uid displaced when valve is operated.
FS99 Flow Sensor
Install FS99 Flow Sensor HORIZONTALLY in RPZ Relief Valve discharge line for proper
operation. Do not install vertically. Consult factory if ow sensor other than FS99 is used.
Client / Contractor to provide 2 FNPT installation Tee for Flow Sensor. Sensor Probes mus
be eld cut to length and installed 1/4 above pipe bottom for proper operation
Insure sensor probes do not contact installation Tee bottom or sidewalls.
Line Voltage to FS99 Flow Sensor is 10 volts maximum.
Electrical Connections
Certied Electrician to connect JB113 Junction Box and FS99 Flow Sensor according to
factory schematic to appropriate power source and terminal strip locations.
Line Voltage to FS99 Flow Sensor is 10 volts.
Power supply to JB113 Junction Box is 120 VAC 60HZ Single Phase.
Connect Limit Switch (if equipped) to remote alarm or auxiliary connection as required by
project specications.
Pre-set Time Delay to 15 seconds.

Start-Up
F113-6RFP (Globe)F1113-6RFP (Angle)
Proper Automatic Control Valve start-up requires bringing the valve into service in a controlled manner. Al
adjustments to control pilots and speed controls should be made slowly, allowing the valve to respond and
the system to stabilize. NOTE: Control Valves should be set-up in a dynamic (owing) condition for
proper start-up. Provisions for ow must be made to insure proper settings.
1. Refer to valve schematic. Disengage Solenoid by turning Manual Operator out (counterclockwise
Open upstream and downstream isolation valves to allow controlled lling of the Valve and Backow
Assembly. Open all Isolation Ball Valves. Adjust speed controls by turning needle in (clockwise) unt
seated, and return out (counterclockwise) 2-1/2 to 3-1/2 turns. These are approximate settings, and
should be ne tuned to suit system requirements.
2. Open Manual Reset Ball Valve. Inlet pressure will activate the Model 22-1 Accelerator and open
the valve fully. Inlet pressure will be indicated on Pressure Gauge. Close Manual Reset Ball Valve
trapping pressure in cover of Model 22-1 Accelerator.
3. Engage Solenoid by turning (red) Manual Operator clockwise (in) to simulate electrical shutdownsignal. Pilot Pressure Gauge will drop to zero and valve will begin to close. Due to low / no ow
condition, valve closure may be slower than normal operation. When valve is fully closed adjus
Limit Switch trip arm and trip collar to actuate Limit Switch.
4. Disengage Solenoid by returning Manual Operator out (counterclockwise) and open Manual Rese
Ball Valve. Inlet pressure will be indicated on Pressure Gauge. Close Manual Reset Ball Valve
Valve will open fully and is ready for electrical activation.
5. Open JB113 Junction Box. Apply power and observe the clear Electric Relay Control.
6. Pour adequate amount of water into RPZ Relief Valve Air Gap until the RED LED indicator light on
the Electrical Relay illuminates / ashes. This indicates the FS99 Flow Sensor is properly installedand is sensing water in the discharge piping.
7. Trap water in discharge piping and observe RED LED on Electrical Relay. Solenoid will energize
when duration of Adjust Time Delay elapses. Valve will go closed and must be manually reset
Adjust Time Delay to Customer / Project specications. To manually reset valve refer to Step 4.
8. For nal test simulate actual RPZ Relief Valve discharge and observe oor drain for excessive
pooling or ooding. Re-adjust time delay and valve speed controls as needed to achieve desired
valve closure time.
