MIX 1 AFV DN25 Smart valve with flood sensors and Wi-Fi control

MIX 1 AFV DN25 Smart valve with leak sensors and Wi-Fi control is a modern electric ball valve for controlling water flow in irrigation, heating, and air-conditioning systems. It is equipped with a Wi-Fi module, mobile app, and leak sensors for automatic protection against water leaks. The valve enables remote, precise adjustment of the opening level, scheduled operation, and automatic water shutoff when a leak is detected, increasing system safety and reducing water consumption.

Brief description

MIX 1 AFV DN25 Smart valve with leak sensors and Wi-Fi control is an electric ball valve for controlling water flow in irrigation, heating, and air-conditioning systems, compatible with the Tuya Smart / Smart Life app. The device allows you to remotely open and close the water supply, set the opening level from 0–100%, and integrate the valve with leak sensors that automatically trigger valve closure if a leak is detected. The 5 V DC power supply, IP65 protection rating, and durable construction materials increase the valve’s reliability and resistance under typical indoor operating conditions.

Who is it for?

• Owners of single-family homes – remote control of the water supply, automatic shutoff when a leak is detected, and greater safety for the water system in the bathroom, kitchen, or boiler room.
• Users of garden irrigation systems – the ability to set MIX 1 AFV DN25 valve opening schedules and precisely control water flow, making it easier to irrigate lawns, flower beds, or greenhouses.
• Building and technical facility managers – automatic flood protection in rooms where a water-system failure could cause significant material losses or equipment downtime.
• HVAC system installers – convenient water-flow control in heating and air-conditioning systems, as well as easy integration with the app and automation systems.
• Smart home users – integration of the MIX 1 AFV smart valve with the app, automation scenes, and voice control (e.g. Google Assistant, Amazon Alexa) within an existing smart home ecosystem.

Applications

• Water-flow control in systems for irrigating gardens, lawns, potted plants, and irrigation systems in greenhouses or on farms, with scheduled operation and valve-opening adjustment.
• Water-flow regulation in heating and air-conditioning systems where precise opening and closing of a DN25 electric ball valve is required.
• Automatic flood protection in rooms exposed to water leaks (bathrooms, kitchens, laundry rooms, boiler rooms, and technical rooms), through the cooperation of the MIX 1 AFV valve with water-leak sensors.
• Creating automation scenes in the app in which leak detection by the flood sensor causes the valve to close automatically and shuts off the water supply.
• Remote control of the water supply in systems where physical access is difficult, using the Wi-Fi module, mobile app, and voice control of the MIX 1 AFV DN25 smart valve.

This MIX 1 AFV DN25 smart valve, as a Wi-Fi water valve with leak sensors, is ideal for domestic and professional systems where automation, water savings, and system safety are important.

Features, description, and technical data

MIX 1 AFV DN25 Smart valve with leak sensors and Wi-Fi control is an electric ball valve with an actuator and Wi-Fi module, designed to control water flow in irrigation, heating, and air-conditioning systems. The valve consists of a ball-valve body, an actuator driven by an electric motor, a Wi-Fi communication module, a panel with a touch switch, and a set of flood sensors that communicate with the app and valve to automatically shut off the water supply.

The valve actuator operates using an electric motor that rotates the valve ball by 90°, enabling the water flow to be fully opened or fully closed. In addition to the two extreme positions, the valve can be adjusted in increments of 10% of the maximum flow, with an accuracy of 5%, allowing the flow capacity to be precisely adapted to system requirements. Control is available through the Tuya Smart or Smart Life mobile app (recommended), using an MCU microcomputer, as well as locally via the touch button on the housing, which allows manual opening and closing of the MIX 1 AFV valve.

The MIX 1 AFV DN25 smart valve operates on 5 V / 2 A direct current supplied by an adapter (the set includes a USB cable, while the power supply must be selected separately – a 5 V / 2 A phone charger is recommended). The housing is made of ABS, while the structural components, including the fittings, are made of 304 stainless steel and engineering-grade plastic, ensuring durability and resistance under typical operating conditions. The valve has an IP65 protection rating, indicating resistance to dust and water jets; however, the manufacturer recommends installation indoors only, in dry, well-ventilated locations protected from weather conditions.

The MIX 1 AFV series includes two-way valves in DN15, DN20, DN25, and DN32 sizes, with NPT‑BSP threads, a maximum operating pressure of 1.0 MPa, and a maximum liquid temperature of 60°C. The permitted ambient temperature range is from 0°C to +40°C, and fully opening or closing the valve takes approximately 30 seconds, ensuring stable and safe operation in typical water systems. The valve is intended for use with clean water free of iron and iron oxides, while operation with contaminated water may lead to damage and failure.

The MIX 1 AFV set includes the MIX 1 AFV smart valve, three flood sensors, a USB power cable, and a key for resetting the sensors. The leak sensors are powered by CR123/CR123A batteries (not included) and provide audible and visual alarms, with current consumption of ≤25 μA in real time and ≤125 mA in the active state. They operate at temperatures from −10°C to +50°C and humidity levels of up to 95%, communicating with the app via an 802.11 b/g/n Wi-Fi network.

The MIX 1 AFV valve control system enables the creation of advanced automation scenes in which the valve closes automatically after a water leak is detected by a flood sensor, cutting off the water supply to the system. Configuration is performed in the app by adding the devices (valve and sensors) to a 2.4 GHz Wi-Fi network, assigning them to the user account, and then creating a scene in which the “leak detected” condition triggers the “close valve” action. This allows the MIX 1 AFV DN25 smart valve to function as an active flood-protection device; however, the manufacturer recommends using additional independent safety solutions in parallel, as system operation may be disrupted, for example, by a power outage or Wi-Fi network problems.

The device’s key advantages include remote valve control through the app or voice assistants, the ability to set operating schedules and a timer, an automatic shutoff function in the event of a power interruption, integration with flood sensors, and simple installation that can be carried out by a person familiar with the operating instructions. The valve enables efficient water-consumption management through precise flow control while increasing safety by protecting against the effects of system failures. Proper installation requires flushing the system, using filters to limit contaminants, having the electrical connection made by a qualified professional, and ensuring suitable environmental conditions, including protection against freezing and high humidity.

The manufacturer’s warranty for the MIX 1 AFV electric valve is 24 months, provided that the original proof of purchase is retained and the recommendations in the operating instructions are followed. Dambat stipulates that the warranty does not cover damage resulting from improper use, external forces, unauthorized interference with the device’s construction, or structural modifications made outside an authorized service center.
