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. _x000D_ _x000D_ 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. _x000D_ _x000D_ Features: _x000D_ 1. Brass valve body, with high strength and good durability. _x000D_ 2. Built-in actuator de-energizes the valve when the valve is fully open or fully closed, safe and energy-saving. _x000D_ 3. Precision structure, tight close, no leakage. _x000D_ 4. The actuator is easy to disassemble and assemble, and can be installed after the equipment and pipelines are installed. _x000D_ 5. Widely used to regulate the fluid flow in ventilation, heating, air conditioning, refrigeration and other pipeline system. _x000D_ _x000D_ Specification: _x000D_ Body Material: Brass _x000D_ Voltage: AC220V _x000D_ Power: 6W 50/60Hz _x000D_ Port Size: DN50 2" _x000D_ Action time: 25s _x000D_ Torsion: 8N.m _x000D_ Close Pressure Difference: 0.6MPa _x000D_ Nominal Pressure: PN16-PN20 _x000D_ Angle: 0-90 _x000D_ Applicable Medium: cold/hot water, 50% ethanol solution _x000D_ Medium Temperature: 5-95 _x000D_ Wiring: zero wire(two color), close valve(brown), open valve(blue)_x000D_ Package Weight: Approx. 1462g / 51.6oz _x000D_ _x000D_ Package List: _x000D_ 1 x Ball Valve
