Features: Motorized ball valve is mainly used to control heating ventilation air conditioning water system. Made of high quality brass, the faucet is sturdy and durable. Three-wire motorized ball valves offer a unique level of control, in particular, they offer two-point control. For more complex systems, automated systems, the 3-wire two-point control system is a good choice. The ball valve is convenient to use and has stable performance. Specification: Material: Brass (faucet), 304 stainless steel (stem), special rubber (sealing), aluminum alloy (pilot base), ABS engineering plastic (pilot cover) Type: 3-wire 2-point control channels Driver motor: hysteresis synchronous motor Driver operating voltage: AC220V Power consumption: 7.5VA Valve pressure: 1.6MPa Allowable pressure difference: 0.13MPa Suitable fluid: cold water, hot water Fluid temperature suitable: 2-90 Ambient temperature: 0-60 Opening time: about 10s Closing time: about 5s Valve connection: G2 (DN50) Weight: 1412g / 49.8 oz (approx.) Method of wiring: SR (two-color): COM BR (brown): Valve closed BL (blue): valve open Package list: 1 * motorized ball valve Installation: 1, Turn off the power before installation and it must be installed by professionals. 2, The flow direction should be the same as the direction arrow on the valve body. 3, The valve should be located above the water tray of the fan, to ensure that the water drops fall into the water tray. 4, the valve and pilot should be installed 60 in the vertical direction, and there should be at least 30mm space above for disassembly. 5, It should suffice space of surrounding pipes, appliances and building for maintenance operations, and ensure that the place is accessible by maintenance personnel through the manhole. 6, Two or more valves cannot be connected in parallel. If a parallel connection is truly necessary, use a relay for isolation. 7, First install the valve and test the pressure with the pipeline, then install the pilot. 8, If the pilot is already installed on the valve, do not apply it. force on the driver during installation and debugging work, otherwise the driver will be damaged. 9, the drive cannot be wrapped with thermal insulation material, otherwise it will affect its heat dissipation. 10, the driver should be reliably grounded with wires of at least 1.5mm, other wires should comply with the electrician's relevant standards. 11, After installation and making sure everything is correct, power on and debug without water. Observe at least three complete operations of the drive, until all parts are normal and correct. 12, after adjustment without water, then debugging with water. The water fluctuation pressure difference in the system should be strictly controlled within 0.13MPa, to ensure the efficiency of the water flow switch valve.
