Solenoid Valves
The world’s largest selection of solenoid valves, designed for the most challenging fluid control applications
The world’s largest selection of solenoid valves, designed for the most challenging fluid control applications
A solenoid valve is a type of valve that is controlled by an electric current. A coil of wire, also called an electromagnet, is energized to create a magnetic field that moves a plunger. This movement opens or closes the valve, allowing or shutting off the flow of liquids or gases through it.
Whether your application requires directional control, proportional or miniature valve technology, Emerson provides the industry standard for reliability, adaptability, and energy efficiency.
Our electronically advanced solenoid valves work better, longer and in more hazardous environments.

常见问题解答
根据阀门运动的形式，调节阀主要有两种类型: 直通型(也称为直通阀或角型阀)或旋转型(也称为角行程调节阀)。直通型调节阀采用线性运动，将关闭部件移入或移出阀座密封表面。而旋转调节阀则通过旋转运动，将密封部件移入或移出阀座密封表面。
压降是入口压力与出口压力之间的差值。它随流量的变化而变化。压降通常以磅/平方英寸 (psid) 为测量单位。
