电动调节阀
ELECTRIC CONTROL VALVE
应用
电动调节阀与电动执行器配套使用，广泛应用于暖通空调水系统、锅炉、热交换系统或空调箱蒸汽系统中，可对系统中的介质进行流量调节。
Apply
Electric regulating valve and electric actuator are used together, widely used in HVAC water system, boiler, heat exchange system or air conditioning box steam system, which can regulate the flow of the medium in the system.
工作原理
电动调节阀应用在暖通空调系统中，在能量的输配和维持水循环系统的水力平衡方面起到非常重要的作用。主要配合末端执行机构，从控制系统接收控制信号和调节阀杆的信号值，而执行器则根据信号值调节阀门开度，改变管网系统的流量。
Working principle
Electric regulating valve is used in HVAC system, which plays a very important role in energy transmission and distribution and maintaining hydraulic balance of water circulation system. It mainly works with the end actuator to receive the control signal and the signal value of the regulating valve stem from the control system, and the actuator adjusts the valve opening according to the signal value to change the flow rate of the pipe network system.

安装说明
1、 注意阀门介质流向应与管路介质流向一致。
2、 阀门可以安装在供水或回水管路上，一般推荐安装在回水管路上(安装在回水管路上可以使水流控制更为平稳同时热水回水部分的温度较低，可延长阀门使用寿命),同时推荐在阀门前安装过滤器和止回阀。当介质为蒸汽时管道上安装排水阀，可以除去凝结水，否则将影响阀门使用寿命。
3、 注意阀门安装方向。
Installation instructions
1, pay attention to the valve medium flow should be consistent with the pipeline medium flow.
2, the valve can be installed in the water supply or return pipe road, it is generally recommended to install on the return pipe road (installed on the return pipe road can make the water flow control more stable while the temperature of the hot water return part is low, which can extend the service life of the valve), and it is recommended to install the filter and check valve before the valve. When the medium is steam, the drainage valve installed on the pipeline can remove the condensate, otherwise it will affect the service life of the valve.
3, pay attention to the valve installation direction.
安装方向
Mounting direction
介质为冷/热水时，不能向下安装 介质为蒸汽时，可以任意角度安装
When the medium is cold or hot water, it cannot be installed downward. When the medium is steam, it can be installed at any Angle
