Mixing thermostatic valve Afriso ATM 343 3/4" model 1234310

Afriso ATM 343 3/4" model 1234310 is a thermostatic mixing valve engineered to deliver stable outlet temperatures in heating and domestic hot water systems. The valve automatically blends hot and cold water to maintain a preset temperature, reducing the risk of scalding and ensuring consistent delivery to radiators, showers or taps. Designed for residential and light commercial installations, this compact device supports reliable temperature control where a steady mixed water temperature is required.

Advantages

The thermostatic mechanism responds automatically to variations in inlet temperatures and pressures, maintaining the selected outlet temperature without manual intervention. The construction is intended for durability in standard hydronic and domestic hot water systems and allows straightforward integration with existing 3/4" threaded pipework. By preventing temperature spikes and thermal shock, the valve helps protect plumbing fixtures and improves user safety.

Suitable for

• Domestic hot water systems supplying showers, bath taps and washbasins
• Heating circuits requiring tempered return or bypass water
• Small commercial installations with moderate flow demands
• Retrofit projects where 3/4" connections are present

Key specifications

• Connection size: 3/4" threaded inlets and outlet
• Function: thermostatic mixing to maintain preset outlet temperature
• Application: domestic hot water and heating systems
• Material compatibility: suitable for standard potable and heating water
• Control: automatic temperature regulation via thermostatic element
• Installation: inline mount with standard plumbing fittings

How to use

Install the mixing valve in the supply line according to the flow direction markings, connecting hot and cold inlets and the mixed outlet to the downstream circuit. Set the desired outlet temperature using the adjustment mechanism provided by the valve, then verify performance by measuring the mixed water temperature at representative outlets. The valve operates automatically once inlet supplies are present; periodic checks and routine maintenance ensure continued accuracy.

Usage recommendations

Before installation confirm system water quality and pressures meet the valve manufacturer's guidelines. Flush installation pipework to remove debris, and fit isolation valves upstream to allow servicing without system drainage. For applications with high mineral content or where anti-scald certification is required, consider appropriate upstream treatment or additional protective devices.
