LEOPARD flow limiter hydraulic diaphragm valve. The flow limiting valves allow to limit the flow of circulating water, ensuring that it is equal to or less than adjusted. Leopard Flow limiter hydraulic valve Leopard flow limiter valves are available from DN 20 to DN 300 diameter. Applications The installation of limiter flow control valves allows to: •Avoid excessive consumption. •Avoid pressure drops and therefore supply deficiencies in network far away points. The flow limiting valves allow to limit the flow of circulating water, ensuring that it is equal to or less than adjusted. Functioning The pilot regulates the opening of the valve according to the differential pressure, providing the pre-set flow rate and keeping the flow constant. By actuating the screw of the pilot’s tare it is possible to vary the flow rate. By two sensors, installed on both sides of an orifice plate that produces a certain pressure drop, the circulating flow is obtained, closing the hydraulic valve partially until only allowing the determined flow if this flow is to be exceeded. After preselecting the flow to be limited, the pilot is able to modify the flow rate set at ± 15%. Turing the limiter pilot clockwise you will allow a higher glow. Turing the pilot anti-clockwise you will reduce the flow.
