Stainless Steel Automatic Air Vent Valve

Precautions for the Use of Automatic Air Release Valves

The performance of an automatic air release valve relies on "correct model selection, installation, and maintenance". Improper operation may lead to exhaust failure, liquid leakage, or component damage.

1

Pressure Matching: The "nominal pressure (PN)" of the air release valve must be ≥ the system's operating pressure. For example, a heating system typically uses a valve with PN 1.0-PN 1.6 MPa.

2

Caliber Matching: Select the caliber based on the pipeline diameter and air displacement. DN 15-DN 25 is commonly used for household/small-scale systems.

3

Material Matching: Choose material according to fluid corrosiveness. For ordinary water, brass is common; for corrosive fluids, stainless steel (304/316L) should be used.

Frequently Asked Questions

How do I choose the correct nominal pressure for the air vent valve? The nominal pressure (PN) of the valve must be greater than or equal to your system's maximum operating pressure to prevent leakages or component failure.

What materials are available for corrosive environments? For corrosive fluids or harsh environments, we recommend using Stainless Steel 304 or 316L, which provide excellent acid and alkali resistance.

What is the standard warranty for these valves? We provide a 12-month product warranty period from the date of acceptance, covering quality problems under correct installation and use.

Can these valves be used for steam applications? Yes, our stainless steel automatic air vent valves are designed to work stably with water, oil, and steam media.

What sizes are commonly available for household systems? DN15 to DN25 are the standard calibers used for small-scale and household plumbing or heating systems.

What services are included in after-sales support? Support includes product certificates, inspection reports, installation instructions, and a commitment to address quality feedback within 48 hours.
