Area of use

MMA’s self-acting thermostatic head ENTL equipped with remote sensor as well as remote adjustment wheel is used to regulate valves in heating and cooling systems.

Description

ENTL is a self-acting thermostatic head designed to achieve best possible temperature regulating function. This type of thermostatic head is used when temperature sensing and setting has to be done away from the position of the valve body, a separate casing is supplied to make it possible to locate the sensor away from the wheel. ENTL standard execution is 10-26 °C but other temperature ranges are available. ENTL has a large indicating window that makes it easy to read and adjust.The symbol * protects against frost protection in i.e room that not is used.

ENTL matches all MMA radiator valves, radiator manifolds and cooling valves. To fit other makes it can be used in combination with one of our adapters.
