Features: Motorized ball valve is mainly used to control the water system of heating, air conditioning and ventilation. Made of high quality brass, the faucet is sturdy and durable. Three-wire motorized ball valves provide a unique level of control, specifically two-point control. For more complex systems, automated systems, the two-wire to 3-wire control system is a good choice. The ball valve is convenient to use and has stable performance. Specification: Material: Brass (valve), 304 stainless steel (stem), special rubber (sealing), aluminum alloy (pilot base), ABS engineering plastic (pilot cover) Type: 2-way control, 3 wires and 2 points Driver motor: hysteresis synchronous motor Driver working voltage: AC220V Power consumption: 7.5VA Valve pressure: 1.6MPa Allowable pressure difference: 0.13MPa Suitable fluid: cold water, hot water Temperature of the Suitable fluid: 2 -95 Ambient temperature: 0 -60 Open time: about 10s Closing time: about 5s Valve connection: G2 (DN50) Weight: about 1412g Wiring method: SR (two-color): COM BR (Brown) : BL valve closed (blue): valve open Package list: 1 * motorized ball valve Installation: 1, Cut off the power before installation and it must be installed by professionals. 2, the flow direction should be the same as the arrow on the valve body. 3, the valve should be located above the fan water pan, to ensure that the water drops fall into the water pan. 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, There should be enough space from the surrounding pipes, appliances and building for maintenance operation, and ensuring 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, valve installed first and test the pressure with the pipeline, then install the pilot. 8, If the driver is already installed on the valve, do not exert any 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 must be reliably grounded with wires of at least 1.5mm. Other wires must comply with applicable electricians' standards. 11, after installation and making sure everything is correct, power on and debug without water. Observe at least three complete operations of the player, until all parts are normal and correct. 12, after adjustment without water, then debug with water. The water fluctuation pressure difference in the system should be strictly controlled within 0.13 MPa, to ensure the efficiency of the water flow switching valve.
