Pressure drops / theorical water flow depending on the valves KVS Dpv max : acceptable maximum differential pressure on the valves on all the modes. In order to avoid all risks of noise and erosion on the seat and the valve, Dpv < Dpv max. operation is necessary. In order to guarantee correct operation and valves lifespan, we recommend: - a correct balancing of hydraulic networks is necessary (use of t-pieces adjusting brackets), - the use of blowdown valves or variable-flow pumps for networks equipped with 2-way valves terminal units, - to guarantee a hydraulic network free from muds or any particles likely to deteriorate the operation of the valves. - an operating Dp in line with manufacturers instructions is available on request to prevent flow noise.
