🔍 Product Description
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.
✔
Model Selection: Match system parameters to avoid undercapacity. The "nominal pressure (PN)" must be ≥ the system's operating pressure.
✔
Caliber Matching: Select based on pipeline diameter. DN 15-DN 25 is common for small systems; DN 50+ for industrial.
✔
Material Matching: Brass/Cast Iron for water; Stainless Steel (304/316L) for corrosive fluids.

❓ Frequently Asked Questions
1. How do I choose the right size for an automatic air vent valve?
Model selection should be based on your pipeline diameter and air displacement needs. DN15-DN25 is standard for residential use, while larger diameters are recommended for industrial systems.
2. What pressure ratings are available?
Our standard automatic exhaust valves are rated at PN1.6MPa. It is critical that the valve's nominal pressure is equal to or greater than the system's actual operating pressure to prevent leakage.
3. Can these valves handle corrosive fluids?
Yes, for corrosive environments or chemical applications, we recommend our 304 or 316L stainless steel models, which offer superior resistance to acid and alkali.
4. What is the standard warranty period for your products?
We provide a 12-month product warranty from the date of acceptance, covering quality problems under correct installation and usage.
5. Do you offer customization for non-standard requirements?
Absolutely. We can customize valve models, materials, and specifications based on the unique technical requirements and drawings provided by our clients.
6. Which fluid media are compatible with these valves?
Our valves are designed to work stably with a variety of media including water, oil, and steam across different temperature ranges.
