Frequently Asked Questions
Q: What voltage options are available for this brass solenoid valve?
A: This G1/2" brass electric solenoid valve is available in three voltage configurations: 12V DC, 24V DC, and 220V AC. Please select the option that matches your electrical system before purchasing.
Q: Is this solenoid valve suitable for solar water heater systems?
A: Yes. This valve is specifically designed for use with solar water heaters and other low-pressure water systems operating within a pressure range of 0.02–0.8 MPa. Its brass construction handles the temperature variations common in solar heating setups.
Q: What does "normally closed" mean for a solenoid valve?
A: A normally closed solenoid valve remains shut when no electrical power is applied, and opens when energized. This is the most common type for water control — it conserves energy and prevents flow during power outages, making it a safe default state for most plumbing applications.
Q: How do I install this G1/2" solenoid valve?
A: Installation is straightforward thanks to the standard G1/2" threaded connections. Thread the valve inline with your water supply line (use thread seal tape for a watertight fit), connect the electrical leads to your power source at the correct voltage, and test for leaks before putting it into regular service.
