Giacomini V81112Q Thermostatic Radiator Valve Body 1/2 inch x 3/4 inch Eurokonus Angle Pattern Nickel-Plated Brass

Thermostatic radiator valve body engineered for precise flow control in hydronic heating systems. The angle pattern with 1/2" male radiator connection and 3/4" Eurokonus pipe connection delivers reliable performance in tight spaces, while the nickel-plated brass body ensures durability and corrosion resistance.

Advantages

This valve body combines robust construction with versatile compatibility. The nickel-plated brass resists corrosion and maintains a clean appearance over time. Its angle design simplifies installation in corner radiator connections, and the Eurokonus fitting provides a secure, leak-free seal without additional adapters. Suitable for both flow and return sides, it offers flexibility in system design. The valve supports water and glycol solutions up to 30%, making it ideal for modern heating systems.

Suitable for

• Hydronic radiator heating systems in residential and commercial buildings
• Installations requiring a compact angle valve for space-constrained areas
• Systems using thermostatic heads from Giacomini R460 or R470 series
• Heating circuits with water or glycol mixtures up to 30%
• Flow or return piping configurations
