Description: Caleffi 553542A AutoFill™ Automatic Filling Valve 1/2" MNPT x 1/2" FNPT Brass553542A1/2" NPT CALEFFI 553542A AutoFill Automatic Filling Valve 1/2" Male NPT (in) x 1/2" Female NPT (out) Pre-adjustable, automatic filling valve Anti-scale with visual system pressure setting indicator Complete with manual shut-off valve, strainer and check valve Brass body Max inlet pressure: 230 psi Max working temp: 150?F Setting pressure range: 3 - 60 psi Preset outlet pressure: 15 psi The automatic filling valve is a device consisting of a pressure reducing valve with compensating seat, visual system pressure setting indicator, an inlet filter, anti-scale internal parts, a shut-off valve and a check valve. It is installed on the water inlet piping in sealed heating systems, and its main function is to maintain the pressure of the system stable at a set value, automatically filling up with water as required. This valve has been designed as pre-adjustable, which means that it can be adjusted at the required pressure value before the system charging phase. After installation, during the filling or topping-off phase, the water feed will stop when the set pressure is reached filling 50% faster than other valves. There are no levers to flip or valve to close. Pre-assembled with the 573 series backflow preventer, the AutoFill� Combo features an atmospheric vent which is designed to protect drinking water systems from return flow, caused by back-siphoning or back pressure, of contaminated fluids. The 573 series has been specifically certified to standards CSA B64.3 and ASSE 1012.
