1The motorized ball valve is mainly used for controlling water system of heating ventilation air conditioning. 2Made of high quality brass material, the valve is sturdy and durable. 3The three wire motorized ball valves offers a unique level of control, specifically, it offers two point control. 4For more complicated system, automated systems, the 3 wire two points of control system is a good choice. 5The ball valve is convenient to use and has a stable performance. Features:The motorized ball valve is mainly used for controlling water system of heating ventilation air conditioning. Made of high quality brass material, the valve is sturdy and durable. The three wire motorized ball valves offers a unique level of control, specifically, it offers two point control.For more complicated system, automated systems, the 3 wire two points of control system is a good choice. The ball valve is convenient to use and has a stable performance. Specification:Material: Brass(valve), 304 stainless steel(stem), special rubber(sealing), aluminum alloy (driver base), ABS engineering plastic(driver cover) Type: 2-Way 3-Wire 2-Point ControlDriver 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 Suitable Fluid Temperature: 2-90 Ambient Temperature: 0-60 Open Time: About 10s Close Time: About 5s Valve Connection: G2 (DN50) Weight: 1412g / 49.8oz(approx.)Wiring Method: SR(Dual-color): COM BR(Brown): Valve Close BL(Blue): Valve Open Package list:1 * Motorized Ball ValveInstallation: 1, Cut off the power supply before installation and it must be installed by professionals. 2, The direction of flow must be the same as the direction arrow on the valve body. 3, The valve should be located above the fan water tray, to ensure that drops of water fall into the water tray. 4, The valve and the driver must be installed within 60 in vertical direction, and there should be at least 30mm space above for dismantling. 5, The should be enough space from surrounding pipes, devices and building for maintenance operation, and making sure the place is reachable by maintenance personnel through manhole. 6, Two or more valves cannot be connected in parallel. If parallel connection is really necessary, use relay for isolation. 7, Installed valve first and test pressure with pipeline, then install driver. 8, If the driver is already installed on the valve, do not apply force on 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 grounded reliably with wires not less than 1.5mm, other wires should be in conformity with the relevant standards of electrician. 11, After installation and making sure everything is correct, power on and debug without water. Observe three complete operation of the drive at least, till all parts are normal and correct. 12, After adjustment without water, then debug with water.The fluctuation pressure difference of water in system must be strictly controlled within 0.13MPa, to ensure the effectiveness of the valve to water flow switch.
