 Valves require a 0.3 bar Minimum Pressure Differential to open. Once open, they remain open with 0.2 bar differential pressure.
 Refer to Steam/Hot Water Valve Series for Hot Water constructions.
 On 50 hertz service, the watt rating for the 6.1/F solenoid is 8.1 watts.
Response time upon energization: 3/8" - 1/2" (2-4 seconds), 3/4" - 1 1/4" (4-8 seconds), 1 1/2" - 2 1/2" (8-10 seconds)
