Thermostatic mixing valve ATM 363 DN20

Description

Thermostatic mixing valve Afriso ATM 363 DN20

APPLICATION

Thermostatic mixing valves ATM are designed to control the hot water temperature prepared for water taps. They should be always used when a need to protect the users from scalding or a fast reaction to temperature or pressure changes is required.

The ATM valves also give the possibility to safely heat the water up in tap water systems to prevent from the Legionella.

The “anti-scald” function closes the hot water inlet in case of cold water lack.

Thermostatic mixing ATM valves can be also utilized in underfloor heating systems as mixing valves before manifolds.

They can work with pure water or mixtures of water and glycol in concentrations of up to 50%.

DESCRIPTION

Thermostatic mixing valves have a body m ade out of DZR brass. The knob allows to change the outlet temperature in the range of 35-60°C (recommended for main water tanks). The knob with two scales (numeric and temperature) provides a slot for an 7 mm Allen key, when having difficulties while changing the temperature. The plastic cover protects from accidental changes in the temperature, while the opening in it allows to check the current setting. One can seal the cover to avoid interference by third parties. The “anti-scald”
function present in every ATM valve blocks the hot water flow in case of cold water failure therefore protecting from scalds.
ATM valves are maintenance-free and can be mounted in every position.
