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.

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):

CERTIFIED ELECTRICIAN TO CONNECT MAIN POWER AND FS99 FLOW SENSOR TO 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 decreases the time delay for valve closure.
