Automatic heating filling fitting, fill combination DN15 ½ "Caleffi

Automatic heating filling valve, filling combination DN15 ½" Caleffi

The automatic heating filling valve consists of a shut-off valve with inspectable strainer, a system separator with

Controllable, pressure-reduced zone type BA and a pre-adjustable filling valve. The filling valve comes complete with a preformed insulation shell and can be easily installed thanks to its compact dimensions.

It must be installed on the filling line of closed-circuit heating systems. Its purpose is to maintain the pressure in the system at a set target value and, if necessary, automatically compensate for the missing water volume. This filling valve can be pre-set, meaning it can be set to the desired target pressure before filling the system.

The system separator prevents the contaminated water from the closed heating circuit from flowing back into the drinking water network, thus ensuring compliance with the requirements of EN 1717.
