进口电动二通阀 三线两控 二线 风机盘管电动二通阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……

　　进口电动二通阀用于风机盘管冷水或热水管道，通过对管道的开启、关断，达到控制室内温度目的。执行器具有弹簧复位功能，当电源断电或系统运行中发生突发断电情况，执行器依靠弹簧力的作用自动复位到关闭位置retz The electrictwo-way valve is used for cold or hot water pipes in fan coil units to controlindoor temperature by opening and closing the pipes. The actuator has a springreset function. When the power supply is cut off or a sudden power outageoccurs during system operation, the actuator automatically resets to the closedposition relying on the action of spring force

　　进口电动二通阀技术参数 Technical paramete

　　风机盘管电动二通阀（三线两控）不工作时处于常闭状态，当需要工作时，由房间温控器提供一个开启信号，使电动阀接通电源而动作，开启阀门，冷冻水或热水进入风机盘管，为房间提供冷量或热量；当室温达到房间温控器设定值时，房间温控器令电动阀断电，复位弹簧动作使阀门关闭，从而截断进入风机盘管的水流。通过阀门关闭和开启，使室温始终保持在房间温控器设定的温度范围内 RETZ electric two-wayvalve (three-wire two-way control) of fan coil is normally closed when it isnot working. When it needs to work, the room temperature controller provides anopening signal to make the electric valve act by connecting the power supply,and open the valve. Chilled water or hot water enters the fan coil to providecooling or heat for the room; When the room temperature reaches the set valueof the room temperature controller, the room temperature controller will cutoff the electric valve, and the return spring will act to close the valve, thuscutting off the water flow into the fan coil. By closing and opening the valve,the room temperature is always kept within the temperature range set by theroom temperature contro
