Mirab co. Fixed Cone Free Discharged Valves are capable of keeping the flow in a constant and steady condition. In addition it can increase the volume of flow in an emergency situation e.g. flood water or etc. (The reason of increasing flow, is preventing any damages to the side walls of dam.) The structure of Fixed Cone Free Discharged Valves are made firmly and rigidly to eliminate any cavitation and vibration and prevent harm to other structures. In high speed of flow, water takes some big solid parts into the valve (such as stones, wooden parts, etc) the structure of valve is so that these parts cannot harm the body of valve and they can pass through the valve and will not make any difficulty for opening and closing.
