Thermostatic mixing valve Afriso ATM 561 DN20 (mpn 1256110)

Thermostatic mixing valve Afriso ATM 561 DN20 is a compact plumbing component engineered to blend hot and cold water to a stable, preset outlet temperature. Designed for DN20 (20 mm nominal diameter) pipe connections, this valve is intended for domestic hot water systems where consistent mixed water temperature and protection against scalding are required. The thermostatic element responds to temperature changes and adjusts flow proportions automatically to maintain the selected temperature even when inlet conditions vary.

Advantages

The Afriso ATM 561 DN20 provides automatic temperature control, reducing thermal fluctuations at outlets. Its compact DN20 size fits common residential and light commercial installations and minimizes pressure drop while delivering required flow rates for showers and washbasins. The valve contributes to user safety by limiting maximum outlet temperature and helps to prevent scalding. Its construction is compatible with typical potable water systems and aims for stable operation over varied inlet temperatures.

Suitable for

• Domestic hot water distribution to showers and washbasins
• Temperature control in apartments and single-family homes
• Light commercial installations where DN20 connections are used
• Point-of-use mixing to reduce scald risk in bathrooms and kitchens

Key specifications

• Connection size: DN20 (20 mm nominal diameter)
• Function: Thermostatic blending of hot and cold water to a preset outlet temperature
• Application: Domestic hot water systems, showers, washbasins, point-of-use mixing
• Control type: Self-acting thermostatic element for automatic temperature regulation
• Installation orientation: Inline mounting with standard plumbing fittings for DN20 pipes

How to use

Install the Afriso ATM 561 DN20 in the cold and hot water supply lines feeding the desired outlet according to local plumbing codes and manufacturer installation guidance. Set the desired mixed water temperature using the valve's adjustment mechanism and verify outlet temperature with a thermometer. After installation, test the system across expected inlet temperature and pressure ranges to ensure stable mixed temperature and proper operation. Periodic inspection and flushing of the connected supply lines are recommended to maintain performance.

Usage recommendations

For reliable operation, install strainers or filters upstream to reduce debris entering the valve, ensure inlet water temperatures and pressures are within the valve's operational range, and follow local regulations regarding backflow prevention. Regular maintenance checks and temperature verification at occupied outlets help maintain safety and comfort.
