Thermostatic mixing valve 1/2", +30 to +50 °C, PN 10, T max.+85 °C, check valve, filter, scald protection
Code: INT_CLF 521714Product detailed description
Thermostatic mixing valves are essential components in plumbing and sanitary systems where precise temperature control is required to prevent scalding and ensure user safety. These valves are commonly installed in residential, commercial, and industrial settings, particularly in applications involving hot water supply to showers, sinks, and hand basins. The valve integrates a temperature-regulating mechanism that blends hot and cold water streams to maintain a consistent and safe output temperature. Installers must consider system pressure, flow requirements, and compatibility with existing piping to ensure correct operation and longevity.
Correct selection and installation of a thermostatic mixing valve are critical to achieving the desired performance. The valve must be sized to handle the expected flow rate and accommodate the maximum operating conditions of the system. It is typically used in conjunction with other components such as filters, check valves, and temperature sensors to enhance system reliability and safety. The presence of a built-in filter and check valve in this model ensures that the valve is protected from particulate matter and backflow, which can affect its performance and lifespan.

Installation and connection
Installation of the thermostatic mixing valve requires a 1/2 inch threaded connection for both the hot and cold water inlets. The valve should be mounted in a location that allows easy access for adjustment and maintenance. It is important to ensure that the inlet connections are clean and free from debris before installation to prevent damage to the internal components. The check valves and filters should be oriented according to the manufacturer's instructions to ensure proper function. A common mistake during installation is incorrect orientation of the valve or failure to secure the connections properly, which can lead to leaks or improper mixing.
Before commissioning, the installer should verify that the valve is correctly connected to the hot and cold water supplies and that the temperature adjustment wheel is set to the desired output. The system should be tested for leaks and the mixed water temperature should be checked to ensure it falls within the specified range. Regular inspection of the connections and internal components is recommended to maintain performance and prevent failures.
Compatibility and accessories
This thermostatic mixing valve is compatible with standard plumbing systems that use 1/2 inch threaded connections. It is suitable for use with copper, PPR, and steel pipes, provided that the connections are properly sealed with appropriate thread sealant or tape. No additional accessories are required for basic operation, as the valve includes a built-in filter and check valve. However, in systems with high particulate content or where backflow prevention is a concern, external filters or check valves may be recommended. Related products such as thermostatic mixing valves with different connection sizes or temperature ranges may be considered depending on the specific application requirements.
Technical background for designers
The operating principle of the thermostatic mixing valve is based on a temperature-sensitive element that expands or contracts in response to changes in the mixed water temperature. This movement adjusts the position of the internal mixing mechanism to maintain the set output temperature. The valve body is protected against dezincification, a form of corrosion that can occur in copper alloys under certain conditions, ensuring long-term durability. The chrome-plated surface provides resistance to wear and corrosion, making it suitable for use in wet environments. The valve is designed to integrate seamlessly into existing plumbing systems and can be used in both new installations and retrofit projects. The service life and efficiency of the valve are influenced by factors such as water quality, operating pressure, and the frequency of temperature adjustments.
Service and operation
Regular maintenance of the thermostatic mixing valve is not required under normal operating conditions. However, it is recommended to periodically inspect the valve for signs of wear, corrosion, or blockages in the filter. If the valve is installed in a system with high particulate content, the filter should be cleaned or replaced as needed to prevent clogging. The temperature adjustment wheel should be checked to ensure it is functioning smoothly and that the output temperature remains within the specified range. In the event of a malfunction, the valve should be isolated and inspected for internal damage or debris. If the problem persists, the valve should be replaced to ensure continued safe operation.
Frequently asked questions
Can the valve be used with hot water up to 85°C?
Yes, the valve is designed to handle input water temperatures up to 85°C, making it suitable for use with high-temperature hot water systems.
Is the valve suitable for use in a closed-loop system?
Yes, the valve can be used in closed-loop systems provided that the operating pressure and temperature conditions are within the specified limits.
Can the temperature setting be adjusted after installation?
Yes, the valve features an adjustable temperature wheel that allows the output temperature to be set between 30 and 50°C after installation.
Does the valve require a separate filter or check valve?
No, the valve includes a built-in filter and check valve, so no additional components are required for basic operation.
