Function: 1. No energy consumption, having direct stability of water regulation 2. Brass cast brass construction is reliable, durable, anti-corrosion and precise 3. Pressure regulating valve (constant flow valve) works similarly to water flow switch 4. This solenoid valve can not only maintain a constant current flow, but also prevent dry burning and monitor the flow 5. Easy to install and maintain Specification: Characteristics: No energy consumption, having direct stability of water regulation. Brass cast brass structure is reliable, durable, anti-corrosion and precise. The pressure regulating valve (constant flow valve) works similarly to a water flow switch. This solenoid valve can not only maintain a constant current flow, but also prevent dry combustion and monitor the flow. Easy to install and maintain.
