一、进口电动单座调节阀概述:

进口电动单座调节阀（美国威盾VTON，Electric single seat control valve）由VTRD型系列直行程电动执行机构和直通单座阀两部分组成，以单相交流220V电源为动力，接受0~10mA或4~20mA直流信号，自动地控制调节阀开度，达到对管道内流体介质的压力、流量、液位等工艺参数的连续调节。电动单座调节阀具有动作灵敏、能源取用方便、信号传输迅速等特点。广泛应用电力、冶金、化工、轻纺等工业自动控制系统中。

The imported electric single seat control valve (VTON, Electric single seat control valve) is composed of two parts: a VTRD series straight stroke electric actuator and a straight through single seat valve. It is powered by a single-phase AC 220V power supply, receives 0-10mA or 4-20mA DC signals, automatically controls the opening of the control valve, and achieves continuous adjustment of process parameters such as pressure, flow rate, and liquid level of the fluid medium in the pipeline. The electric single seat regulating valve has the characteristics of sensitive action, convenient energy access, and rapid signal transmission. Widely used in industrial automatic control systems such as power, metallurgy, chemical industry, and light textile.
