LEOPARD flow limiter and pressure reducer hydraulic diaphragm valve. The combined reducing and limiting valve performs both functions independently.
Leopard Flow limiter and pressure reducer hydraulic valve
Leopard flow limiter and pressure reducer valves are available from DN 20 to DN 300 diameter.
Applications
The combined reducing and limiting valve performs both functions independently. It allows to:
•Avoid excessive consumption.
•Avoid pressure drops and therefore supply deficiencies in network far away points.
•High pressures that can damage components of the installation.
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 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.
The reducing pilot acts on the valve so that it has a modulating function, in order to keep the downstream pressure constant for the set control value.
