Water hammer Prevention Control Valve is a system that prevents energy waves that occur as a result of power cuts in longer water mains supply lines, pumping systems and automatically discharges pulses that occur as a result of sudden changes in water speed to the atmosphere, as a result of pumps switching on and off in the system. It is a safety control valve designed to protect The valve opens quickly by sensing the decreasing pressure wave with its pressure signal pipe and low pressure pilot. When the line pressure reaches the normal level, the valve automatically closes itself slowly.
