Stainless Steel Threaded Vent Valve
Product Description
Product Overview
The stainless steel threaded air vent valve is a valve device designed to automatically discharge trapped air or gas from liquid-carrying pipeline systems (e.g., water, oil). By efficiently removing air pockets, it prevents airlocks, ensures stable system operation, enhances fluid transfer efficiency, and prolongs equipment service life.
Product Structure
1.Materials
- Valve Body/Cover: 304/316 stainless steel for superior corrosion resistance and high-temperature tolerance, suitable for harsh environments.
- Internal Components: Float ball (stainless steel or corrosion-resistant composite), valve stem, sealing rings (EPDM/NBR fluororubber).
- Connection Type: Threaded (G pipe thread or NPT standard).
2.Design Features
- Compact structure for installation in space-constrained areas.
- Automatic opening/closing mechanism with rapid response, requiring no manual intervention.
- Dual-seal design to prevent leakage during gas discharge.
Working Principl
When gas accumulates in the pipeline, the liquid level in the valve chamber drops, causing the float ball to descend and open the vent port via the valve stem. Once gas is expelled, liquid refills the chamber, lifting the float ball to close the vent port and prevent liquid leakage.
Applications
- HVAC Systems: Heating pipelines, air conditioning water circulation.
-Water Supply/Drainage: High-rise building water networks, firefighting pipelines.
- Industrial Equipment: Boiler systems, heat exchangers, solar thermal circulation.
-Others: Hydraulic systems, chemical liquid transfer pipelines.
Product Advantages
1.Corrosion Resistance: Stainless steel construction ensures durability in humid, acidic, or alkaline environments.
2.High Efficiency: Rapid air removal prevents cavitation, noise, and energy loss.
3.Easy Installation: Threaded connections simplify installation without specialized tools.
4.Low Maintenance: Modular design allows easy disassembly for cleaning or component replacement.
