The PURG-INOX 2000® has been developed for reliable continuous operation in closed heating, cooling, and solar systems. Its all-stainless-steel construction ensures high resistance to temperature and media, as well as consistently reliable air release.
The result of over 30 years of experience in the development of air vent valves:
- Fully made of stainless steel AISI 316Ti (1.4571)
- Directly controlled float without levers, springs, or mechanical transmission
- Permanent automatic air release
- Leak protection integrated as standard; leak protection cap permanently open for continuous venting
- No flooding of the valve seat at increasing pressure – resulting in low contamination risk and high operational reliability
- Removable stainless steel valve seat – cleanable
- Valve seal made of Viton®, heat-resistant and durable
- High temperature resistance up to 150 °C
- Suitable for water and water-glycol mixtures (up to 40%)
- Optionally available with vacuum breaker
- Made in Germany
Operating Principle
The PURG-INOX 2000® operates with a directly controlled stainless steel float. Air accumulates in the housing, causing the float to drop and open the valve. Once the air has been released, the float rises again and closes the valve. By eliminating mechanical levers or springs, the risk of jamming, contamination, or malfunction is significantly reduced.
Applications
- Heating and cooling systems
- Solar installations
- Systems with stainless steel components
PURG-INOX 2000 float air vents are designed for permanent automatic air release and static installation in heating, cooling, and solar systems, as well as in tanks and systems operated with water or water-glycol mixtures.
Manufacturing is carried out in accordance with relevant standards, such as VDI/VDE 3907 “Materials for Precision Engineering – Stainless Steels.” The hollow bodies are properly welded according to the current state of the art and are individually tested for tightness using a differential pressure testing device. Corrosion resistance can be ensured provided the boundary conditions of DIN 6601 “Resistance of Materials of Steel Tanks/Vessels to Liquids (Positive List)” issued by the Tank Systems Committee (ATANK) within DIN e. V. are met.
When using the float air vents with media or additives other than those mentioned above, which are not included in the positive list, no liability can be assumed. Certain vibration frequencies may lead to failure of the welded joints. For operating conditions other than those described, it is generally recommended to verify suitability for the intended application through practical testing, particularly with regard to material properties and functionality.
