This electric solenoid valve features a complete brass casting structure, ensuring precision and reliability. It is wear-resistant, anti-corrosive, and capable of withstanding high temperatures. Features: This solenoid valve functions similarly to a water flow switch with pressure regulation properties (steady flow functionality). It maintains a constant flow and current while preventing dry burning and monitoring flow rates. It operates mechanically without power consumption, and the flow is adjustable. The valve is designed for durability, with high resistance to wear, corrosion, and extreme temperatures. Suitable for applications involving water, premium water heaters, smart drinking fountains, water heaters, direct drinking machines, water purification units, steam equipment, energy-efficient air conditioning, water treatment, cooling systems, and various sectors within the water industry. Specifications: Material: Brass Voltage: 12V DC / 24V DC / 220V AC Nominal diameter: G1/2" Water pressure: 0.02-0.8Mpa Size: 6.5 x 6 x 3.5cm Package included: 1pc Note: 1. There may be slight color variations due to lighting and display influences. 2. Please allow for size differences of about 1-3cm due to manual measurement. Thank you for your understanding.
