22mm 2 Port Zone Valve
The zone valve is driven by a high-performance electric actuator and automatically opens or closes according to the signal from the controller. When the valve is opened, hot or cold water can flow into the floor heating pipes or radiators to regulate the indoor temperature; once the temperature reaches the preset value, the controller will issue a command to close the valve and block the water flow, thereby ensuring that the system can operate energy-efficiently and efficiently.

Application scenarios
Heating system: In central heating or independent heating systems, 22mm 2-port zone valves can be used to control heating in different areas. For example, a building is divided into multiple areas, and each area uses a zone valve to control the inflow and outflow of hot water to achieve independent adjustment of the temperature of different areas.
Hot water supply system: A hot water supply system suitable for homes or commercial places, which can control the flow direction and flow of hot water to ensure a stable supply of hot water. For example, in hotels, hospitals and other places, it is necessary to accurately control the hot water supply in different rooms or areas, and 22mm 2-port zone valves can meet this demand.
FAQ
1. Can this valve be used in floor heating systems?
Yes, the 22mm 2 port zone valve can be used in floor heating systems, allowing precise control of floor heating in different zones to achieve comfortable temperature distribution.
2. Will the valve get stuck when not used for a long time?
If not used for a long time, the valve may get stuck due to sediment or corrosion in the water. It is recommended to operate it regularly to keep the valve unobstructed.
3. Can this valve be used with solar heating systems?
Yes, it can be used with solar heating systems as long as the medium in the system (such as water) is within the temperature range of the valve (0°C to 90°C).
4. Can the valve be used with refrigerants in cooling systems?
The valve is generally designed for water systems and is not suitable for handling corrosive gases or liquids such as refrigerants. It is recommended to consult the manufacturer to confirm specific media compatibility.
5. Can the valve's actuator be integrated with an existing smart home system?
Yes, many 22mm 2 port zone valve actuators support connection to smart thermostats or smart home systems for remote control and automation management.
