Air vent valve Uponor HYPAIR 32–63 (model 1134572) for hydronic systems

The Uponor HYPAIR 32–63 air vent valve (model 1134572) is a venting component engineered for hydronic and heating systems to remove entrained air. Designed for compatibility with pipe dimensions in the 32–63 mm range, this valve helps prevent air locks, improves circulation and heat transfer, and reduces noise in domestic and light commercial installations. The compact design allows installation on circulation lines and heating manifolds where reliable automatic air elimination is required.

Advantages

The valve provides continuous automatic air separation without manual intervention, supporting stable system operation and minimizing on-site maintenance. Its construction is suitable for integration into manifold assemblies and pipe runs within the specified diameter range, enabling consistent flow and reducing the risk of corrosion or uneven heating caused by trapped air. The product’s design focuses on straightforward installation and durability under normal hydronic system conditions.

Suitable for

• Residential central heating systems
• Underfloor heating manifolds
• Small commercial hydronic circuits
• Circulation loops in boiler and heat-pump systems

Key specifications

• Applicable pipe diameters: 32–63 mm
• Function: automatic air vent for hydronic systems
• Installation position: suitable for manifold and inline mounting on circulation lines
• Intended media: water-based heating fluids used in hydronic systems
• Operational benefit: continuous air removal to improve heat transfer and reduce noise

How to use

Install the air vent valve at a high point in the circuit or on the manifold where air naturally accumulates, following local plumbing codes and the system manufacturer’s instructions. Ensure the pipe connection matches the 32–63 mm dimension range and that the valve is oriented as recommended for automatic venting. After installation, pressure-test the system and purge remaining air from the circuit; the valve will continue to expel small amounts of entrained air during normal operation.

Usage recommendations

For reliable performance, mount the valve where it remains accessible for visual inspection and occasional maintenance. Do not use with aggressive chemical additives unless confirmed compatible with valve materials. Periodically check the system for leaks and verify that the vent remains operational as part of standard hydronic system maintenance.
