6. Product features: 6.1. Valve system The generated torque of current valve system is three times larger than the one that valve required, which will ensure smooth valve operation even in bad condition such as fouling, long-time idle and impurity substance. a. Valve technical parameter Test condition: pressure P=1.0MPa, Flow rate Q=2m3/hour, Power supply V=3V( 1Pcs 18505 or 1Pcs 14505 or 2Pcs 14505 lithium battery) 6.2. Flow characteristic Semi liquid sealed mechanism is adopted and its flow characteristic meets or exceeds the related national standard. Benefiting from the adoption of ball-valve system, the pressure loss is much lower than the meter of other type of valve structure. Its flow characteristic will highly welcome by water supplying company. 6.3. Signal sampling system Adoption of high-end hall component and alternate mode are equal to bistable state, which will avoid the measuring error resulting from tremble.
