FAQ

Q1. What is a Solenoid Valve?

A solenoid valve is an electromechanical device used to control the flow of liquids or gases. It consists of an electric coil (the solenoid) and a movable plunger. When energized, the magnetic field moves the plunger to open or close the valve orifice.

Q2. What are the benefits of Hearken's IP68 coils?

An IP68 rating ensures the valve coil is completely dust-tight and waterproof, even under continuous submersion. This is critical for harsh outdoor environments, smart irrigation, and industrial wash-down areas.

Q3. Why is "Smart" valve technology important?

Smart valves monitor their own performance and cycle counts. This allows facilities to move from scheduled maintenance to predictive maintenance, replacing parts only when actual wear is detected.

Q4. How do I choose between NBR and Viton seals?

Choose NBR (Nitrile) for standard water and oil applications at moderate temperatures. Use Viton (FKM) for high-temperature environments or when handling aggressive chemicals.

Q5. Can one valve handle both AC and DC power?

Most traditional coils are specific to one power type. However, advanced manufacturers like Hearken now offer multi-voltage coils with integrated electronics that can accept various AC and DC inputs without needing to swap hardware.
