Type BV3 (3-way) For high-pressure humidification and adiabatic cooling systems Flow coeficient Kv [l/min] Differential Material pressure [bar] Coil type Order code FEATURES: • Single valve designed for high-pressure humidification and adiabatic cooling applications. • Separate drain port for convenient pressure relief and nozzle drip prevention. • Valve is operated by a pair of coils, one NC (main line) and one NO (pressure relief). Manifold version also available. FUNCTION: P = IN A = OUT R = DRAIN At power off the main path (P-A) is shut, but the drain stays open to allow pressure relief and prevent nozzle drip.
