Frequently Asked Questions (FAQ)
Q: Is the 2W160-15 solenoid valve suitable for drinking water? A: The standard 2W160-15 model features a brass body and NBR seal. While it is excellent for general water systems, irrigation, and industrial fluid control, it is not NSF-certified for potable (drinking) water. Please ensure your application requirements align with standard industrial-grade brass valves.
Q: Does this valve require a minimum pressure to operate? A: No, this is a direct-acting, semi-direct-acting diaphragm valve. Unlike pilot-operated valves that often require a minimum pressure of 0.5 bar or higher to stay open, the 2W160-15 can function effectively from 0 PSI. It is an ideal choice for gravity-fed tanks or low-pressure water lines.
Q: What is the difference between Normally Closed (NC) and Normally Open (NO)? A: This model is Normally Closed (NC), meaning it remains closed when the power is off and opens when the coil is energized. This is the most common safety-focused configuration for water and air systems, ensuring the fluid is shut off automatically in the event of a power failure.
Q: How do I choose the correct voltage for my application? A: Choosing the right voltage depends on your power source.
-
12V DC / 24V DC: Best for mobile applications (vehicles, battery-powered systems) or where safety regulations require low-voltage controls.
-
110V AC / 220V AC: Standard for fixed industrial, residential, or commercial installations.
-
Note: Always ensure the voltage printed on the coil matches your power supply to prevent coil damage.
Q: Can I use this valve for diesel or light oil? A: Yes, the NBR seal is compatible with diesel and light non-corrosive oils. However, please avoid using this valve with highly aggressive chemicals, strong acids, or high-temperature steam (above 80°C), as these will damage the rubber diaphragm.
