These automatic water control valves are designed for high pressure service, in vertical or horizontal installations and are available in diameter sizes from 1½” to 16”; DN40 to DN400. The BERMAD 700E valves are used for water flow control in Deluge, Pressure Control Deluge, Preaction or Water/ Foam systems, and are manufactured from materials suitable for freshwater or alternative for seawater, foam concentrate or other corrosive fluids. The 700E Deluge Valve is held closed by system water pressure trapped in the control chamber. When the releasing system operates, pressure is released from the control chamber, and the seal disc opens to allow water to flow into the system. The 700E valve body design includes a single, full bore seat with unobstructed flow path, free of any in-line ribs, supporting cage, or stem guides. The 700E “Y Type” design provides high flow capabilities with minimum head loss. The integral unitized double-chambered actuator provides a combination of positive, immediate response with smooth hammer-free, drip-tight closing. The whole actuator can be easily removed for a quick in-line inspection and servicing. Valve actuation is accomplished by one moving assembly which includes a replaceable flat diaphragm, harnessed to the diaphragm assembly, a stainless steel stem and a flat seal disk assembly. The balanced seal-disk assembly with its resilient seal enables controlled actuation, high durability and perfect drip-tight sealing, even under harsh conditions. Accessories The BERMAD 700E Deluge Valve shall be trimmed with the original components and accessories per specification and in accordance with valve functions and applications. Where additional specifications and/or signaling devices are required for a specific application, refer to system data for the system used, and to the BERMAD data sheet and Installation, Operation & Maintenance for specific model required.

Valve Open (Operating Conditions) Releasing the pressure from the upper control chamber to atmosphere or some other lower pressure zone causes the line pressure acting on the seal disc to move the valve to the open position. Proper operation of the 700E Deluge Valves depends upon their trim being installed in accordance with the appropriate trim configuration. Notes: ■ Wet pilot height should not exceed “Maximum Elevation Above Valve” (see data for specific model). ■ Any deviation in trim size or arrangement may adversely affect the proper operation of the deluge valve. ■ All the pilot system devices, must be UL Listed and compatible with the particular deluge system. Refer to current “UL Listed Fire Protection Equipment Directory”. Warning: The deluge valve and trim must be installed only in areas where they will not be subject to freezing temperatures. Installation Instructions 1. Allow enough room around the valve assembly for any adjustments and future maintenance. 2. Before the valve is installed, flush the pipeline to remove any dirt, scale, debris, etc. Not flushing the line may result in the valve’s becoming inoperable. 3. Install the valve in the pipeline so that the valve flow arrow appearing on the body casting is pointing in the desired direction. Ensure that the valve is positioned so that the actuator assembly can be easily removed for future maintenance. 4. Ensure that the Control Trim is mounted properly and all other components are positioned correctly as per illustration. 5. After installation in the main line, carefully inspect/ correct any damaged accessories, piping, tubing, or fittings. Ensure that there are no leaks. 6. Install the components comprising the Deluge Trim Package in their proper positions in compliance with all instructions, drawings, and technical specifications describing the BERMAD Deluge Valve, according to the relevant illustration. 7. All additional accessories, although not packed together with the BERMAD Deluge Valve, must be installed as shown in the relevant P&ID and other illustrations. Operation Principle of Operation The BERMAD 700E Deluge Valve (assembled with specific trim) is suitable for systems that include adequate detecting and piping systems with open nozzles. The deluge valve prevents water from entering system piping until required. The deluge valve is kept closed by pressure applied to the upper control chamber through a restricted priming line. In the SET position, the water pressure supplied through the priming line is trapped in the upper control chamber of the deluge valve by a check valve, and by the normally closed release device. The pressure trapped in the upper control chamber of the deluge valve presses the valve seal disk down, thereby sealing the valve and keeping the system piping dry. Under conditions of FIRE, when the pressure is released from the upper control chamber by the opening of the automatic releasing device or by manual release, the deluge valve opens and allows the inlet supply water to flow through the valve and into the system piping and alarm devices. Warning: Whenever the handle of the Manual Emergency Release is pulled, pressure is released from the upper control chamber, the deluge valve will open, and water will flow into system piping and alarm devices. Installation 6 BERMAD Fire Protection 700 SeriesFP 700E Installation, Operation & Maintanence Placing in Service/Resetting The deluge valve and the control trim shall be Placed in Service with accordance to the most recent IOM procedures for the specific model. After all relevant instructions are performed, slowly open the supply-isolating valve and check that no water flows into the system. The system is now operational and in stand-by mode. Maintenance Bermad Deluge Valves require no lubrication, no packing tightening, and require a minimum of maintenance. Removing the System from Service Warning: When taking a deluge system out of service, a fire patrol should be established in the system area. If automatic fire alarm signaling equipment is utilized, the proper authority should be notified that the system is being removed from service. The insuring body and owner’s representative should also be notified when the system is being taken out of service. Removal Instructions 1. Shut off the main supply-isolating valve. 2. Close the priming line valve to the deluge valve control chamber. 3. Open all drain valves. 4. Release the water pressure from the control chamber of the deluge valve by pulling the manual emergency release. 5. Place "Fire Protection System Out of Service" signs in the area protected by the system. Inspection and Testing 1. Warning:Do not turn off the water supply to make repairs without placing a roving fire patrol in the area covered by the system. The patrol should continue until the system is back in service. 2. Prior to turning off any valves or activating any alarms, notify local security guards and the central alarm station, if used, to avoid signaling a false alarm. 3. The deluge valve and the control trim shall be maintained with accordance to the most recent IOM procedures for the specific model. A periodic test schedule should be established also with accordance to the site conditions and owner regulations. 4. Take all additional measures as required by NFPA-25 “standard for the inspection, testing, and maintenance of water-based fire protection systems”. 5. The system should be checked weekly for “Normal Conditions”. 6. Clean the priming strainer prior to any resetting of the deluge valve. 7. The deluge valve must be activated at full flow at least annually. Take all necessary precautions to drain water and prevent damage in the area protected by the system. 8. After about five years of operation, replacement of diaphragm and other elastomers is recommended. Remove the actuator and disassemble it. Clean the seat area from sediments, clean the control tubing entry holes, and install a new diaphragm and other elastomers in place. Spare Parts 1. The Diaphragm and the Seals are the only spare parts needed for the main deluge valve, see attached “Valve Disassembly and Parts Breakdown” illustration. 2. It is not recommended to store spare rubber parts for long periods (rubber in improper storage conditions can harden and crack). 3. Contact your Bermad representative and order new rubber parts when required. 7 BERMAD Fire Protection 700 Series Bearing Assembly Shaft Diaphragm Washer O-Ring Diaphragm Spacer Disk Diaphragm Washer Nut Indicator Lock Nut Cover Disk Bolt Cover Plug (6” and up) O-Ring Eye Nut Bearing Screw Disk Separation Partition Bolt Stud Nut Locking Screw Seal Disk Assembly Seal Disk Wash.
