1)The kv-value indicates the water flow (Q) in m3/h at a pressure drop (∆p) across the valve of 1 bar; kv = Q: √∆p. The kv-value is stated according to EN 215, at XP
=2K, i.e. the valve is closed at 2°C higher room temperature. At lower settings the XP value is reduced to 0.5K. The kvs-value states the flow Q at a maximum lift, i.e. at fully open valve.
2)Kvs-value for RLV-S/HC: 1.26 m3/h
3)Working pressure = static + differential pressure. The maximum differential pressure specified is the maximum pressure at which the valves give satisfactory regulation. As with any device which imposes a pressure drop in the system, noise may occur under certain flow/pressure conditions. To ensure quiet operation, maximum pressure drop should not exceed 30 to 35 kPa. The differential pressure can be reduced by the use of the Danfoss differential pressure regulators.
