Automatic Air Vent Valve Prestigio 1/2" 10 bar angled

The Automatic Air Vent Valve Prestigio 1/2" 10 bar angled is an angled automatic air eliminator designed for heating and domestic water systems. It discharges trapped air continuously and automatically to improve fluid circulation, reduce noise and limit corrosion in closed-loop circuits. The valve features a 1/2" threaded connection and a compact, angled body that enables installation in tight spaces on radiators, manifolds and pipe runs where top or side mounting is impractical.

Advantages

This Prestigio automatic air vent provides reliable unattended air removal, helping maintain system efficiency and consistent heat distribution. The angled configuration simplifies installation in confined areas and on angled manifolds. Constructed for service under pressures up to 10 bar, the valve offers robust operation in typical residential and light commercial heating systems. Its automatic operation reduces the need for manual bleeding and routine intervention.

Suitable for

• Domestic and small commercial heating systems
• Radiators and convectors
• Manifolds and distribution headers
• Piping runs and compact installations with limited vertical space

Key specifications

• Connection size: 1/2" threaded
• Maximum operating pressure: 10 bar
• Angled body for side or top mounting
• Automatic continuous air venting mechanism
• Compact dimensions suitable for tight spaces

How to use

Install the valve at high points in the system or at locations where air tends to accumulate, such as radiators, manifolds or upward pipe runs. Ensure the 1/2" threaded connection is sealed with appropriate sealing material and tightened to the manufacturer-recommended torque. The valve operates automatically once the system is filled and pressurised; no manual action is required during normal use. Periodically inspect the valve for external leaks and accessibility, and replace if signs of wear or malfunction appear.

Usage recommendations

For optimal performance, fit the valve in a vertical or slightly angled orientation that allows free air rise to the outlet. Use compatible materials and follow local codes for installation pressure and temperature limits. Regular system maintenance and water quality control will prolong service life and prevent premature clogging.
