Function and design The pressure regulating valve (steady flow valve) functions similarly to a water flow switch. This DC 12V solenoid valve can keep a steady flow, help prevent dry running, and monitor the flow. performance Built with a professional manufacturing process for reliability, wear resistance, and temperature resistance. It features no power consumption and provides direct stability of water adjustment. Easy to use Easy to install and maintain, this water solenoid valve is a suitable replacement for an old or broken unit. Specifications: Voltage DC 12V; nominal diameter 1/2 inch; water pressure 0.020.8 MPa; size 6.5 x 6 x 2 cm (2.56 x 2.36 x 0.79 in). Key specifications Model: normally closed water control solenoid valve Voltage: DC 12V Nominal diameter: 1/2 inch Water pressure range: 0.020.8 MPa Size: 6.5 x 6 x 2 cm Configuration: normally closed Application type: water control valve for steady flow and regulation Wide applications Normally Closed Water Control Solenoid Valve is practical and suitable for water systems, end water heaters, intelligent drinking fountains, water heaters, straight drinking machines, water purification machines, steam machines, energysaving airconditioning, water treatment, cooling equipment, and other areas of the water industry. Use scenarios In a end water heater to regulate flow, protect components, and ensure stable operation. In intelligent drinking fountains and water purification systems to deliver consistent flow and prevent dry running. In steam machines and cooling equipment to maintain precise water supply and improve energy efficiency.
