Filling valve with manometer ALM 0240200

Automatic filling valve with manometer – reliable system replenishment

This automatic filling valve, manufactured by WATTS, is a practical solution for replenishing and maintaining the appropriate pressure in closed heating systems. Its design combines functionality, durability and ease of use, making it a good choice for both professional installers and end users. The valve is equipped with a manometer, which allows for precise control of the pressure in the system.

Construction and application

The ALM valve is designed to automatically replenish water in heating systems. It has a built-in check valve to prevent backflow of water, a manual shut-off valve to allow isolation of the valve if necessary, and a filter (steel mesh) to protect against contaminants. Additionally, it is equipped with an air vent to facilitate the removal of air from the installation. The 50 mm diameter manometer with a range of 0-4 bar allows for continuous monitoring of the working pressure. The brass housing provides strength and corrosion resistance, and the plastic cap protects against mechanical damage.

Key features and benefits

• Automatic replenishment: Eliminates the need to manually check and replenish the pressure in the installation, saving time and ensuring stable system operating conditions.
• Built-in manometer: Enables precise control of the working pressure, which is crucial for the correct functioning of the heating installation.
• Check valve: Prevents backflow of water, protecting the system from contamination and ensuring its efficiency.
• Filter (steel mesh): Protection against contaminants – extends the life of the valve and the entire installation.
• Manual shut-off valve: Allows easy isolation of the valve during servicing or repair without having to shut down the entire system.
• Durable construction: The brass housing ensures long-term reliability and corrosion resistance.
• Easy installation: Standard 1/2" female thread facilitates integration with the existing installation. A 1/2" male thread inlet (screw-on to 3/4" male thread) further increases installation flexibility.

This valve is used in domestic central heating installations, underfloor heating systems and other applications requiring automatic water replenishment under pressure. Its solid construction and precise operation guarantee trouble-free operation for a long time.
