COMFORT UNIT CONTROLS theoRetiCaLwateRfLowRatepRessuRe/ dRops, based on the Kvs ofthevaLves Pressure drop in kPa The limits of use vary depending on the suppliers and the type of valve used. Refer to the commercial offer. ∆pv max.: Maximum permissible differential pressure on the valve at all speeds. To prevent any risk of noise and erosion of the seat and valve, an operating ∆p < ∆pv max. must be observed. To guarantee correct operation of the valves and ensure their service life, we recommend: - Ensuring the hydraulic networks are correctly balanced (use adjustment tees), - The use of discharge valves or variable flow pumps for networks equipped with terminal units regulated by 2-way valve(s), - Ensuring the hydraulic system is free of sludge or any other particles liable to adversely affect the operation of the valves. - An operating ∆p in line with manufacturers' instructions is available on request to prevent flow noise.
