100-DC Series hYflow Pressure Relief QUICK PRESSURE RELIEF VALVE, DOUBLE CHAMBER Model IR-13Q-DC The BERMAD Model IR-13Q-DC is a double chambered, hydraulically opearted, diaphragm actuated control valve designed to relief excessive line pressure when it rises above the preset maximum. It responds to rises in system pressure immediately, accurately and with high repeatability, by opening fully. The BERMAD Model IR-13Q-DC provides smooth drip tight 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 ■ Ultra-high flow capacity at Low pressure loss [1] ERMAD Model IR-13Q-DC protects system from B pressure spikes [2] Pressure Reducing Valve [3] Combination Air Valve [4] Electromagnetic Water Meter [5] Kinetic Air Valve 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 ֺ System Burst Protection ֺ Momentary Pressure Peak Elimination ֺ System Failure Visual Indication ֺ Filter Burst Protection Operation: The Pressure Relief Pilot commands the valve to open immediately should the upstream pressure P1 abruptly rise above pilot setting, and to close smoothly when it falls below pilot setting, sealing drip tight. The Cock Valve 2 enables manual operating test.
