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.

Start-Up


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.
