Specification: Condition: 100% Brand New Model: DN15 3 Wire 2 Control Valve Body Material: Brass Valve Rod Material: 304 Stainless Steel Sealing Material: Special Rubber Driver Base Material: Die-Cast Aluminum Driver Cover Material: Flame Retardant ABS Engineering Plastics Driver Motor: Hysteresis Synchronous Motor Power Consumption: ≤7.5VA Valve Body Pressure: 1.6Mpa Allowable Pressure: ≤0.13Mpa Applicable Medium: Cold Water, Hot Water Applicable Medium Temperature: 2℃-90℃ Applicable Environment Temperature: 0℃-60℃ Open Time: About 10 seconds Close Time: About 5 seconds Valve Connection Mode: G1/2 Weight: Approx. 517g / 18.2oz Height: Approx. 12cm / 4.7in Size: Approx. 7 x 6.3cm / 2.8 x 2.5in Diameter: Approx. 2cm / 0.8in Package List: 1 x Motorized Ball Valve Installation and Commissioning: 1. Before the installation must carefully read the instructions, cut off the power and must be installed by professionals. 2. Flow direction must be the same as the direction of the arrow on the valve body. 3. The valve body must be located above the fan water tray, to ensure that the drip drop into the water tray. 4. Valve body and driver must be installed in the vertical direction ±60° range, it should have at least 30mm space above. 5. The building must maintain enough maintenance operation space, and must be installed in the maintenance that repairing person can reach. 6. Two and more than two of the electric valve can not be parallel, if the need for parallel relays to be separated. 7. The valve body is installed and the pipeline through the test pressure before installing the drive. 8. If the driver has been installed on the body, then during the installation and commissioning it must not force on the drive, otherwise it will damage the drive. 9. Drive can not be wrapped with insulation material, otherwise it will affect its heat dissipation. 10. Drives must be reliable grounded by conductors not less than 1.5mm, other lines shall conform to the relevant standards of electrician. 11. After installation and check it correct, do not water-energized commissioning. Please observe the three full operating cycles of the drive to determine for a minute if the parts are normal and correct. 12. After the water-free commissioning, then start the water commissioning. The pressure difference between the upper and lower water of the system must be strictly controlled within 0.13MPa to ensure the effectiveness of the electric valve on the flow switch. Package List
