## Overview

The Caleffi 553140 is a premium 1/2 inch automatic filling fitting designed for closed heating systems. Featuring a calcification-resistant metal body, an internal preset pressure regulator with a built-in gauge, it maintains stable system pressure (0.3-4 bar) and automatically refills missing water. Rated for up to 16 bar and 70°C, it ensures durability and precision, making it an essential upgrade for efficient, low-maintenance heating management.

## Description

Function The automatic filling fitting consists of a pressure regulator with compensating valve seat, a mud flap in the entrance, a shut-off valve and a backflow preventer. It is installed in the water inlet pipe of closed heating systems and its main task is to keep the system pressure stable at a set value and ensure the automatic overflow of missing water. After installation, the water inlet stops in the filling or refilling phase when the setting pressure is reached.
