It is normally open and closes when continuous relief valve discharge through the drain pipe is sensed by the FS99 Flow Sensor, energizing the Solenoid Pilot. The valve is equipped with a Solenoid By-Pass valve (normally closed) which manually closes the Main Valve when engaged. The valve mounted JB11 Junction Box is equipped with an adjustable time delay to avoid valve closure due to intermittent or nuisance relief valve discharge. The Position Indicator provides local, visual indication of valve closure and is useful during valve start-up and troubleshooting. The valve remains closed and cannot re-open if flow 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 JB11 Junction Box with adjustable time delay, pre-wired Solenoid Valve, Manual Reset with Gauge, Position Indicator and FS99 Flow Sensor (field installed). The SentryPlus Alert Wireless Node Junction Box (WN11) ships loose with 6 feet of interconnecting cable and will be field mounted.

Technical Bulletin - LFF11RFP Specifications The Flood Protection Shutdown Valve shall be a normally open Diaphragm Valve installed upstream of the Reduced Zone Backflow Assembly, and automatically close if the RPZ relief valve begins to discharge. A Time Delay supplied in the JB11 Junction Box shall prevent the valve from closing on intermittent discharges from the RPZ relief valve. If continuous Relief Valve discharge occurs, the FS99 Flow Sensor installed horizontally in the RPZ Relief Valve discharge piping shall send a signal to the JB11 Junction Box energizing Solenoid to close the main valve. Once closed the Flood Protection Shutdown Valve must be manually reset. The Electronics Junction Box (JB11) connects to Wireless Node Junction Box (WN11) for wireless communication alerting the user via text, phone or email. Additionally, an extra set of Remote Trip Indication terminals allow users to get remote alarms at their Building Management System (BMS) / PLC controller in the Control Room. The JB11 Junction Box shall be valve mounted with the Solenoid pre-wired. The FS99 Flow Sensor shall be provided with the valve package and shall be field installed in a horizontal position in the RPZ Relief Valve discharge piping. Vertical installation of the Flow Sensor shall not be acceptable. The valve shall be equipped with a Position Indicator to provide local visual indication of valve closure. The Position Indicator shall be a stainless steel indicating rod which follows main valve stem movement as seen through a cylindrical Pyrex sight tube. The Reduced Zone Backflow Assembly, Flood Protection Shutdown Valve, JB11 Junction Box and FS99 Flow Sensor shall be provided by the same manufacturer and be covered by a single warranty policy. The main valve shall be a hydraulically operated, single diaphragm actuated, globe or angle pattern valve. Y-pattern valves shall not be permitted. The valve shall contain a disc and diaphragm assembly that forms a sealed chamber below the valve cover, separating operating pressure from line pressure. The diaphragm shall be constructed of nylon reinforced Buna-N, and shall not seal directly against the valve seat and shall be fully supported by the valve body and cover. Rolling diaphragm construction will not be allowed and there shall be no pistons operating the main valve or any pilot controls. The main valve body and cover shall be Ductile Iron ASTM A56, and all internal cast components shall be Ductile Iron or CFM (16) Stainless Steel. All Ductile Iron components, including the body and cover, shall be lined and coated with an NSF 61 Certified Epoxy Coating applied by the electrostatic heat fusion process. All main valve throttling components (valve seat and disc guide) shall be Stainless Steel. The valve body and cover must be machined with a 60-degree locating lip to assure proper alignment. The disc and diaphragm assembly shall contain a Buna-N synthetic rubber disc with a rectangular cross-section that is securely retained on -1/ sides by a disc retainer and disc guide. Diaphragm assemblies utilizing bolts or cap screws for component retention will not be permitted. Direction of flow through the valve shall be the under-thedisc design. The exposed portion of the seat disc shall contact the valve seat and seal drip-tight. The disc and diaphragm assembly must be guided by two separate bearings, one installed in the valve cover and one concentrically located within the valve seat, to avoid deflection and assure positive disc-to-seat contact. Center guided valves will not be permitted. The main valve spring shall be the manufacturer s heavy or extra heavy spring design. All necessary repairs shall be made from the top of the valve while the body remains in line. The Pilot Control System shall contain a Flo-Clean Strainer, NEMA 4, 10 VAC 60HZ -Way Solenoid with Manual Operator, Manual Reset Ball Valve, Gauge, Visual Position Indicator, JB11 Junction Box and Isolation Ball Valves on all body connections. The JB11 Junction Box shall be valve mounted and the FS99 Flow Sensor shall be field installed. The valve shall be Watts 11FP (globe) or 111FP (angle) Wireless Smart Flood Protection Shutdown Valve.
