FARG 503/1 Automatic Boiler Filling Valve with Manometer 1/2''

FARG 503/1 Automatic Boiler Filling Valve with Manometer 1/2'': The Intelligent Protector of Heating Systems

In closed-circuit heating systems (combi boilers, boilers, radiators), the water level, and therefore the pressure, can drop. This reduces system efficiency and can lead to malfunctions. The FARG 503/1 automatic boiler filling valve with pressure gauge comes into play to automatically solve this problem. FARG is an Italian brand and an expert in this field. Connected to the installation's main water line, this valve detects the pressure drop in the system and adjusts the water level to the desired level, ensuring the system maintains optimal pressure at all times.

What is FARG 503/1 and What Does It Do?

The FARG 503/1 is also known as a "fill group," combining multiple critical functions in a single, compact unit. Its 1/2-inch connection diameter makes it ideal for domestic and small commercial heating systems.

Main Functions:

• Automatic Pressure Reduction and Filling: Reduces the high water pressure from the mains to a lower, constant pressure required by the boiler system. When system pressure drops (e.g., below 1.5 bar), it automatically begins filling with water and stops when the set pressure (e.g., 3 bar) is reached.

• Pressure Monitoring: Thanks to the integrated manometer , users can easily monitor the current pressure in the installation. This feature offers great convenience when adjusting valves or monitoring the overall health of the system.

• Backflow Prevention: The internal check valve located in the device body prevents the water in the heating system (possibly dirty water) from flowing back into the mains line.

• Filtration: It increases the life of the device and the cleanliness of the boiler system by filtering particles that may come from the network.

• Manual Shutdown: There is a shut-off valve (lower black cover) that can be used to stop the device when necessary.

Features and Advantages of the FARG 503/1 Automatic Boiler Filling Valve:

• All-in-One Design: Combines components such as pressure reducer, check valve, filter and shut-off valve into one compact body.

• Automatic and Reliable Control: By keeping the system pressure within the ideal range, it ensures efficient operation of the combi boiler and boiler and prevents malfunctions that may arise from excessive pressure.

• Wide Setting Range: It has a pressure setting range generally 1.5 - 3 bar , suitable for domestic and commercial heating systems.

• Durable Material: Made of high-quality brass and nickel-plated. This is resistant to corrosion and rust, ensuring long-lasting and reliable use.

• Wide Application Area: Suitable for all closed heating systems including central heating, boiler and combi boiler installations.

Areas of Use of FARG 503/1:

• Combi and Boiler Systems: Used to keep the water pressure constant in closed circuit heating systems.

• Individual and Central Heating Systems: Managing water level and pressure in all closed circuit heating installations.

• Solar Energy Systems: Controlling the pressure of solar heated water.
