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 overwhelmed 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 113-12RFP Flood Protection Shutdown Valve is a normally open valve designed to be installed upstream of a Reduced Pressure Zone (RPZ) Backow Prevention device. It is normally open and closes driptight 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 ow stops or electrical 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 Solenoid Valve, Manual Reset with Pressure Gauge, Limit Switch and FS99 Flow Sensor (eld 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.

The valve pilot circuit is equipped with a Model 60 Flo-Clean Strainer which is used to lter the uid passing through the control pilot circuit, and provide protection to pilot circuit speed controls and pilots. It is installed in the inlet body port of the main valve, exposing the strainer element to main line ow. The currents and ow across the screen create a self-scouring effect, cleaning the lter element.

The Model 51 Single Limit Switch provides local visual and remote electrical indication of valve position. The adjustable collar is set to contact the trip arm when the main valve is closed. The collar can be positioned on the stem by loosening the set-screw to actuate the switch upon valve closure. The single pole double throw Micro-Switch can be connected to the building monitoring system to indicate valve closure.

Control Valve

• Fully read all technical information provided.

• Prior to installation ush line to remove debris.

• Install valve upstream of the RPZ Backow Assembly.

• For ease of valve service and electrical connections do not install valve vertically. Install

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 buttery 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” chart

on page 2 to determine volume of cover uid displaced when valve is operated.

F1113-12RFP (Angle)

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 must 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

• Certied 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 specications.

• Pre-set Time Delay to 15 seconds.

• Insure Solenoid is disengaged by turning Manual Operator counterclockwise (out / left).

Start-Up

Proper Automatic Control Valve start-up requires bringing the valve into service in a controlled manner. All 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 counterclockwise (out). Locate and open Manual Reset Ball Valve. Open upstream and downstream isolation valves to allow controlled lling of the Valve and Backow Assembly. Open all Isolation Ball Valves.

2. Inlet pressure will open the valve fully. Close Manual Reset Ball Valve.

3. Engage Solenoid by turning (red) Manual Operator clockwise (in) to simulate electrical shutdown signal. Inlet pressure will be indicated on Pressure Gauge 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 adjust Limit Switch trip arm and trip collar to actuate Limit Switch.

4. Disengage Solenoid by returning Manual Operator out (counterclockwise) and open Manual Reset Ball Valve. Pilot System Pressure Gauge will drop to zero. Valve will open fully and is ready for electrical activation. Allow for cover volume to discharge to oor drain. Refer to chart on Page 2 for Cover Chamber Volume. Close Manual Reset Ball Valve.

F1113-12RFP (Angle)

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 installed and 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 specications. 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.
