How to Test the Quality of a Solenoid Valve?

[MacReagan]

On the DCS, send an open or close signal to the two-position valve, and then observe whether the solenoid valve is energized or de-energized. Generally, you can listen for sounds on-site. Here are some related introductions about the quality of solenoid valves: 1. Sealing Performance of the Solenoid Valve: The sealing performance of a solenoid valve directly determines whether it will leak. Currently, solenoid valve seals are mainly of two types: hard seals and soft seals, each suitable for different media. 2. Sensitivity and Reliability of the Solenoid Valve: This refers to how sensitive the solenoid valve is to changes in media parameters and its corresponding reactions. For solenoid valves such as throttle valves, pressure reducing valves, regulating valves used to adjust media parameters, as well as safety valves and pigging valves with specific functions, their functional sensitivity and reliability are crucial technical performance indicators.
