Advantages

This thermostatic mixing valve offers exceptional precision in temperature control, which is essential for maintaining system efficiency and protecting sensitive components from thermal stress. The high-quality materials used in its manufacture ensure resistance to wear and corrosion, contributing to a longer service life and reduced maintenance requirements. Its compact design allows for straightforward installation in tight spaces, while the reliable internal mechanism provides consistent performance even under varying pressure conditions.

Suitable for

• Underfloor heating systems
• Domestic hot water circuits
• Heating and cooling distribution manifolds
• Temperature control in hydronic installations

When it may not be suitable

This valve is not intended for use in high-pressure industrial steam systems or applications involving aggressive chemical fluids that could damage the internal seals. It is also not suitable for systems requiring rapid, automated electronic modulation without the appropriate thermostatic head or actuator compatibility.

Key specifications

• Connection size: 3/4 inch
• Valve type: 3-way thermostatic mixing valve
• Application: Heating and cooling systems
• Material: Durable brass alloy

How to use

The Herz CALIS-TS valve should be installed by a qualified professional in accordance with the system's flow requirements. Ensure that the flow direction matches the markings on the valve body to guarantee correct mixing performance. Once installed, the thermostatic head or actuator must be calibrated to the desired temperature range to achieve the intended mixing ratio. Regular inspection of the connections and the valve body is recommended to ensure there are no leaks and that the mechanism remains free of debris.

What to consider before purchase

• Verify that the 3/4" connection size is compatible with your existing piping infrastructure.
• Ensure the system pressure and temperature ratings align with the valve specifications.
• Check if an additional thermostatic head or actuator is required for your specific control application.

Usage recommendations

For optimal performance and longevity, it is recommended to install a filter or strainer upstream of the valve to prevent sediment from interfering with the internal mixing mechanism.
