The electric ball valve drive adopts metal drive parts to drive the open or close of the valve. The product is mainly used for on-off control of HVAC, central heating and water supply system. It consists of two parts: the actuator and the valve body. The actuator is driven by synchronous motor, no noise, constant action, and built-in travel limit switch, which can make the valve power off when it is fully open or fully closed.It is widely used in heating, ventilation, air conditioning, refrigeration and other building automation systems, which regulates the fluid flow in the piping system by controlling the open or close of the valve, to achieve a comfortable greenhouse environment.Features:1. Brass valve body, with high strength and good durability.2. Built-in actuator de-energizes the valve when the valve is fully open or fully closed, safe and energy-saving.3. Precision structure, tight close, no leakage.4. The actuator is easy to disassemble and assemble, and can be installed after the equipment and pipelines are installed.5. Widely used to regulate the fluid flow in ventilation, heating, air conditioning, refrigeration and other pipeline system.Specification:Body Material: BrassPower: 6W 50/60HzPort Size: DN50 2"Action time: 25sTorsion: 8N.mClose Pressure Difference: 0.6MPaNominal Pressure: PN16-PN20Angle: 0-90Applicable Medium: cold/hot water, 50% ethanol solutionMedium Temperature: 5-95Wiring: zero wire(two color), close valve(brown), open valve(blue)Package Weight: Approx. 1462g / 51.6ozPackage List:1 x Ball Valve.
