How to Properly Maintain a Normally Open Solenoid Valve?

With a little care, your normally open solenoid valve will last a long time. One way to maintain a valve is to clean it on a regular schedule. Using appropriate tools (such as those provided in a maintenance kit), you can complete this operation without completely disassembling the valve parts. In addition to regular cleaning, if you notice leakage, excessive noise, or slow operation, you should clean the valve as soon as possible.

To improve the characteristics of the valve system, please avoid using mismatched liquids; an SMC normally open solenoid valve will cause premature damage if you do so. In addition, never let the substance inside the valve freeze. Likewise, always keep the contents of the valve at an appropriate temperature and pressure.

The specifications your solenoid valve must comply with depend on your application, industry, and location.

For example, if your valve will come into contact with drinking water, then your solenoid valve must be lead-free. In the United States, drinking water and pipeline standard RO (reverse osmosis) equipment need to pass NSF certification and/or comply with NSF 61-G (leachate and lead-free regulations formulated by the NSF (National Sanitation Foundation)). If you need to use your electrically controlled normally open solenoid valve overseas, they need to obtain lead-free certification from NSF International and be recognized by ANSI and the Canadian Standards Council.

In addition, NEMA (National Electrical Manufacturers Association) provides standard names for valve applicability. Generally speaking, the larger the NEMA model, the more severe the exposure the valve can withstand. For example, a NEMA 1 valve is especially suitable for indoor applications, while NEMA 7 and 9 valves are most suitable for environments with explosive dust or vapor.

When looking for a solenoid valve for your application, you must ensure that the manufacturer you work with can meet all your specifications, including certification, delivery time, and budget. Sometimes, it is beneficial for a high-temperature normally open solenoid valve to study a fast-shipping plan rather than a standard shipping option. Don't forget to discuss this with your potential supplier. In addition, you need to consider a manufacturer that provides excellent terminal software. This means they will provide installation assistance, on-site training and consultation, part maintenance, and part replacement after installation.
