Mixing Thermostatic Valve CALEFFI 1" male thread, temperature range 20–43°C

The CALEFFI Mixing Thermostatic Valve 1" male thread with adjustable temperature range 20–43°C is a thermostatic mixing device engineered to blend hot and cold water and deliver a stable outlet temperature for sanitary fittings. Designed for domestic and light commercial plumbing systems, this valve helps maintain a chosen water temperature at taps and showers while reducing the risk of scalding. The compact 1" male threaded body allows direct connection into supply lines or installation manifolds where reliable temperature control is required.

Advantages

This thermostatic mixing valve provides accurate thermostatic regulation across the 20–43°C range, ensuring rapid response to changes in inlet temperatures and pressures. Built for continuous operation in sanitary installations, it reduces thermal shock and scald risk while promoting consistent comfort at outlets. The 1" male threaded connection simplifies replacement or retrofit in existing piping layouts and supports straightforward mechanical installation without complex adapters. Materials and internal thermostatic elements are designed for durability and stable performance under normal domestic and light commercial water system conditions.

Suitable for

• Domestic bathrooms and showers requiring anti-scald protection
• Washbasins and kitchen taps where temperature control is needed
• Light commercial sanitary installations such as small offices, guest rooms or clinics
• Retrofit projects and replacement of existing mixing valves with a 1" connection

Key specifications

• Connection type: 1" male threaded inlet/outlet compatible with standard plumbing fittings
• Adjustable temperature range: 20–43°C for outlet temperature setting
• Function: thermostatic mixing to blend hot and cold water and maintain setpoint
• Application: sanitary installations for taps, showers and washbasins in domestic and light commercial systems
• Control: mechanical thermostatic element providing automatic regulation and thermal shut-off in case of supply failure

How to use

Install the valve into the mixed water line using the 1" male threaded connections following local plumbing codes and best practices. Set the desired outlet temperature by adjusting the thermostatic control to any value within the 20–43°C range, then verify the mixed water temperature at the fixture with a calibrated thermometer. After initial setup, periodically check operation and temperature stability; the valve will automatically modulate to compensate for fluctuations in inlet temperatures or pressures.

Usage recommendations

For safe operation, ensure hot water supply temperature exceeds the chosen setpoint by an appropriate margin to allow correct thermostatic action, and fit strainers or filters upstream if water quality could introduce debris. Regular inspection and maintenance according to manufacturer guidelines will preserve accurate temperature control and service life.
