In What Main Areas Are Normally Open Solenoid Valves Applied?

A normally open solenoid valve is a kind of plastic normally open solenoid valve, and there are many classifications in this respect, for example: PVC normally open solenoid valve, CPVC normally open solenoid valve, PTFE normally open solenoid valve; most products are corrosion-resistant normally open solenoid valves. These classifications mainly differ in material, but there is not much difference in application, so this issue explains its main application directions.

I. Application of normally open solenoid valves

UPVC, also called rigid PVC, is an amorphous thermoplastic formed by the polymerization of vinyl chloride monomer, with certain additives added. It has high mechanical strength, good wear resistance, high-temperature resistance, and good insulation, and has good adaptability to general corrosive liquids.

1. Special structural technology of UPVC solenoid valves.

2. Completely isolating the liquid from the metal parts (moving iron core, torsion spring), the liquid-use normally open solenoid valve achieves true corrosion resistance.

3. A valve plate made with a piston mechanism extends the life of the solenoid valve.

4. The guide hole has a very large diameter and the channel is very short and straight, so it will not be blocked by solid particles, sediment, or crystals in the liquid (sand and mud in water, crystals in brine).

5. It uses a built-in seal for better sealing performance.

6. The superiority of an electrically controlled normally open solenoid valve is better.

7. The flow path of the solenoid valve is standard and meets the corresponding flow requirements.

8. The solenoid valve is suitable for sewage treatment, agricultural irrigation, seawater desalination, and mariculture. In industrial production, it shows significant advantages with acidic and alkaline liquids, especially for easily crystallizing liquids such as phosphoric acid.

9. For the commonly used UPVC material, the three-position normally open solenoid valve seals are certified for health and safety by the American Health Foundation. They meet global hygiene standards.
