100-DC Series hYflow Flush-’N-Stop FLUSH-’N-STOP VALVE, DOUBLE CHAMBER Model IR-100-LMOe The BERMAD Model IR-100-LMOe is a double chambered, hydraulically operated, diaphragm actuated control valve suitable for automatic flushing of distribution lines at the beginning and the end of each irrigation cycle. Equipped with an auxiliary opening spring, it enables automatic opening when the system reaches closure pressure and settable opening rate, ensuring line pressure build-up for secure closing. ֺ Hydraulic Control Valve ■ ■ ■ Line pressure driven Short response time Long term drip tight sealing Engineered Plastic Valve with Industrial Grade Design ■ Adaptable on-site to a wide range of end connection sizes and types ■ Highly durable, chemical & cavitation resistant ֺ hYflow ‘Y’ Valve Body with “Look Through” Design ■ [1] ERMAD Model IR-100-LMOe opens when the system B reaches closure pressure flushing dirt and sediment out, and shuts off upon line pressure build-up when irrigation begins. [2] Control Pressure Inlet Ultra-high flow capacity at Low pressure loss Full powered opening and closing Decreased pressure loss Low throttling noise Non-slam closing characteristic Protected diaphragm Simple in-line inspection and service Typical Applications ֺ Distribution Line Flush-’n-Stop ֺ Drip Systems ֺ Sprinklers & Micro-Sprinklers ֺ Irrigation Machine Line Flush-’n-Stop Operation: Irrigation Line Pressure 1 pressurizes the Upper Control Chamber 2 , forcing the Diaphragm 3 actuated Plug 4 to move towards the closed position, thereby shutting the Valve. When irrigation stops, system pressure drops, allowing the Spring 5 opening force to overpower the hydraulic closing force. The spring force then pushes the diaphragm, thereby opening the Valve, which remains open. When irrigation starts again, a water stream flushes the line through the opened Valve. Valve resistance enables pressure to build up and rise until the pressure in the control chamber creates hydraulic closing force higher than the spring opening force, and the valve shuts off.
