Thermostatic mixing valve 1", +30 to +48 °C, PN 10, T max.+90 °C

Product detailed description

This thermostatic mixing valve is commonly used in residential and commercial sanitary systems where precise temperature control is required for safety and comfort. It ensures that mixed water remains within a safe temperature range, preventing scalding while maintaining user comfort. The valve is suitable for applications such as showers, sinks, and other domestic hot water outlets where temperature stability is critical. Installers should ensure that the valve is integrated into a system with adequate pressure and flow balance to maintain accurate mixing under varying load conditions.

The valve is typically installed in systems where hot water is supplied at up to 90°C and cold water is available at ambient temperature. It is not intended for industrial or high-pressure applications beyond its specified PN 10 rating. The 1-inch threaded connections allow for straightforward integration into standard plumbing systems. Installers must verify that the upstream and downstream piping can accommodate the flow rate and pressure conditions specified for the valve.

Technical parameters

Installation and connection

Installation begins with selecting a suitable location where the valve can be easily accessed for maintenance and adjustments. The valve is connected using 1-inch threaded connections, typically with male threads. Installers should use appropriate sealing materials such as PTFE tape or thread sealant to prevent leaks. It is important to ensure that the cold and hot water inlets are correctly aligned with the valve’s designated ports to avoid incorrect mixing ratios. After installation, the system should be tested to confirm that the valve maintains the set temperature under normal operating conditions.

A common mistake during installation is neglecting to balance the pressure between the hot and cold water supplies, which can lead to unstable mixing and inaccurate temperature control. Installers should also verify that the valve is not exposed to excessive vibration or thermal stress, which could affect its long-term performance. A pressure regulator or balancing device may be required in systems with uneven pressure distribution.

Compatibility and accessories

This valve is compatible with standard plumbing systems that use 1-inch threaded connections. To complete the installation, additional components such as pressure regulators, temperature sensors, or flow restrictors may be required, depending on the system design. Installers should ensure that all associated components are compatible with the valve’s specifications, particularly regarding pressure and temperature limits. No related products are listed for this model.

Technical background for designers

The valve operates on a thermostatic principle, using a temperature-sensitive element to adjust the mixing ratio of hot and cold water. The brass body provides durability and resistance to corrosion, while the chrome plating enhances surface protection and ease of cleaning. The valve is designed to integrate into systems with balanced pressure and flow rates to ensure consistent performance. Long-term efficiency depends on maintaining clean water supply lines and avoiding exposure to aggressive media or excessive thermal cycling.

Service and operation

Regular inspection is recommended to ensure the valve continues to operate within its specified temperature range. Installers should check for signs of wear, such as leaks or inconsistent temperature control, and clean the internal components if necessary. There are no specified service intervals in the brief, so maintenance should be performed as needed based on system performance and usage conditions. If the valve fails to maintain the set temperature, it may indicate a need for recalibration or replacement of internal parts.

Frequently asked questions

Can this valve be used with a recirculation system?
This valve is not designed for use in recirculation systems due to potential changes in flow dynamics affecting temperature stability.

Is it possible to adjust the temperature setting after installation?
Yes, the temperature can be adjusted manually using the valve’s control mechanism after installation.

Does the valve require a specific orientation during installation?
The valve should be installed with the correct inlet ports aligned for hot and cold water to ensure accurate mixing.

Can this valve be used in systems with non-potable water?
It is suitable only for potable water applications as per the manufacturer’s specifications.
