Giacomini R200X001 plumbing valve

Giacomini R200X001 plumbing valve is an automatic air vent for heating radiators, made from chrome-plated brass with a self-sealing mechanism. Supplied in packs of 10 pieces, this valve removes trapped air from radiator systems to improve circulation and heating efficiency. The chromed finish provides corrosion resistance and a professional appearance suitable for visible installations.

Advantages

The valve’s automatic operation allows continuous venting without manual intervention, reducing maintenance needs and preventing noisy or uneven heating. Chrome-plated brass construction ensures durability and resistance to corrosion while providing a neat aesthetic. The self-sealing feature prevents water loss after air discharge, maintaining system pressure and reducing the risk of leaks.

Suitable for

• Automatic venting of residential and commercial radiators
• Replacement of manual air vents in hot water heating systems
• New installations where concealed or visible chrome fittings are required

Key specifications

• Type: automatic air vent valve for radiators
• Material: brass with chrome plating
• Function: self-sealing air release after venting
• Quantity: pack of 10 pieces
• Application: hot water central heating systems

How to use

Install the valve at the highest point of the radiator or at a designated air-bleed point in the heating circuit, following the radiator manufacturer’s guidelines for thread type and orientation. Ensure the system is depressurized before removal of an existing vent or fitting of a new valve. Once fitted and tightened to the recommended torque for the connection material, the valve operates automatically to expel trapped air. Periodic visual checks are advised to confirm correct operation and to detect any signs of damage or loosening.

Usage recommendations

Use compatible thread sealant or PTFE tape suitable for heating systems on threaded connections, and avoid overtightening to prevent damage to chrome plating. For optimal performance, fit the valve in an accessible position for inspection and replace any valve that shows persistent leakage or mechanical failure.
