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 113-6RFP Flood Protection Shutdown Valve
is a normally open valve designed to be installed upstream of a Reduced Pressure Zone (RPZ) Backow
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.

Maximum continuous flow based on velocity of 20 ft. per second.
Maximum intermittent flow based on velocity of 25 ft. per second.
The Cv Factor of a value is the flow rate in US GPM at 60° F that will cause a 1 psi drop in pressure.
The factors stated are based upon a fully open valve.
Cv factor can be used in the following equations to determine Flow (Q) and Pressure Drop (∆ P):
Q (Flow) = Cv ∆ P

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 decreases the time delay for valve closure.
