Giacomini R402HX003 Angle Thermostatic Radiator Valve 1/2 inch M30x1.5

The Giacomini R402HX003 is a professional-grade angle thermostatic radiator valve engineered for precise thermal regulation in hydronic heating systems. This chrome-plated valve is designed to manage the flow of hot water into radiators, allowing users to maintain specific room temperatures with high accuracy. It features a standard 1/2-inch connection for iron pipes and an M30x1.5 interface, making it compatible with a wide range of thermostatic heads. The unit includes a protective cover to ensure the integrity of the valve body during the installation process.

Advantages

This valve offers exceptional durability due to its high-quality chrome-plated construction, which resists corrosion and ensures a long service life in various heating environments. The thermostatic design allows for significant energy savings by automatically adjusting the heat output based on the ambient room temperature, preventing overheating and reducing fuel consumption. Its precise M30x1.5 connection ensures seamless integration with most modern thermostatic actuators, providing a reliable and responsive control mechanism for residential and commercial heating systems.

Suitable for

• Residential heating systems with iron piping
• Commercial office heating installations
• Replacement of manual radiator valves to improve energy efficiency
• Systems requiring precise individual room temperature control

This valve may not be suitable for systems with very high flow rates that exceed the valve's nominal capacity or for installations where the piping material is incompatible with the 1/2-inch iron pipe connection. It is also not intended for use in steam heating systems or environments with highly aggressive chemical compositions that could damage the chrome plating.

Key specifications

• Connection size: 1/2 inch
• Interface type: M30x1.5
• Configuration: Angle pattern
• Material: Chrome-plated metal
• Compatibility: Standard thermostatic heads

To install the valve, ensure the heating system is drained and depressurized. Connect the valve to the radiator inlet and the iron pipe using appropriate sealing materials to prevent leaks. Once the valve body is securely mounted, remove the protective cover and attach the compatible thermostatic head by screwing it onto the M30x1.5 interface until it is hand-tight. After installation, refill the system and check for any signs of leakage at the connection points.

What to consider before purchase

• Verify the pipe diameter and thread type of your existing heating system
• Ensure the M30x1.5 interface is compatible with your chosen thermostatic head
• Check the available space for an angle-pattern valve installation
• Confirm the valve is suitable for the operating pressure of your heating circuit

For optimal performance, it is recommended to install the thermostatic head in a position where it is not obstructed by curtains or furniture, as this allows for accurate ambient temperature sensing and efficient operation of the heating system.
