Giacomini R200X002 plumbing valve

Giacomini R200X002 plumbing valve is an automatic air vent valve designed for radiator and hydronic heating systems. Manufactured in chrome-plated brass with a self-sealing mechanism, this valve removes trapped air from pipelines and radiator bodies to maintain efficient heat transfer and stable system operation. The product is supplied in packs of 10 pieces for installation professionals and system builders.

Advantages

The chrome-plated brass construction provides corrosion resistance and long service life in heating environments. The automatic air vent function continuously evacuates air without manual intervention, reducing noise, improving circulation and helping prevent cold spots in radiators. The self-sealing feature prevents water leakage when the valve is under pressure or during maintenance operations.

Suitable for

• Automatic air removal from radiator bodies in residential and commercial heating systems
• Use in hydronic circuits and boiler-fed central heating loops
• Replacement of worn or leaking air vents on radiators and convectors
• Installation by HVAC technicians and plumbing professionals

Key specifications

• Material: chrome-plated brass body
• Function: automatic air vent with self-sealing mechanism
• Application: radiator and hydronic heating systems
• Finish: chrome plating for enhanced corrosion resistance
• Supply format: packaged in groups suitable for multiple installations

How to use

Install the valve at the highest practical point of the radiator or on the designated air vent port following the radiator manufacturer's instructions. Tighten the valve to the recommended torque using appropriate tools, ensuring a leak-free connection. Once installed, the valve operates automatically: trapped air accumulates at the vent and is expelled through the valve while the self-sealing mechanism closes when water reaches the outlet. Periodically inspect the valve for proper operation and signs of external corrosion or damage.

Usage recommendations

For reliable function, install the automatic air vent in accessible positions for visual inspection and occasional maintenance. Use with compatible radiator fittings and follow system flushing procedures before commissioning to minimize debris that can impair the vent. If signs of persistent leakage or blockage appear, replace the valve to restore proper venting performance.
