ATM mixing valve for heating system and sanitary applications
The new AFRISO ATM thermostat mixing valves are suitable for water and water/glycol mixtures with a maximum concentration of 50 % glycol. The mixing valves can be used to adjust hot water in sanitary applications such as showers or in smaller underfloor heating circuits which are connected to the flow line (max. 60 C). In applications involving the heating up of drinking water by means of solar systems, a mixing valve must be installed upstream of the taps in order to reduce the temperature of the hot water from the boiler (max. 95 C) and protect the user against scalds. However, the mixing valves can also be installed in surface heating systems such as wall or underfloor heating systems which require constant water temperatures to avoid damage to floors and pipes.

The ATM mixing valve consists of a brass body with an integrated thermostat insert, and an adjustment element, a regulator and a valve housing made of high-resistant plastic. The adjustment element features a scale from 16. The water temperature at the MIX outlet is set according to a table in the operating instructions. A protective cap covers the adjustment element to protect against inadvertent settings or incorrect operation. If the cold water admixture is interrupted, the ATM valve responds extremely fast and automatically shuts off the hot water supply to avoid scalds. ATM has been designed for temperatures of the medium of up to 95 C and a nominal pressure of 10 bar. It has a flow rate of 1.6 m/h. The ATM valves are available in various versions with nominal diameters DN 15 or DN 20, with female or male thread at both ends (Rp3/4 female, G3/4 male and G1 male) and for the two operating temperature ranges 20/43 C (sanitary) und 35/60 C (heating).

The new ATM mixing valves comply with EN 1111 and are fully maintenance-free.
New series ATM thermostat mixing valves for heating system and sanitary applications
The new AFRISO ATM thermostat mixing valves are suitable for water and water/glycol mixtures with a maximum concentration of 50% glycol. The mixing valves which can be used, for example, for showering applications, in underfloor heating circuits and in wall or underfloor heating systems feature integrated scald protection and are fully maintenance-free.
