RKARVO-200 – 2" Aluminum Air Release & Vacuum Relief Vent – Epoxy Orange
The RKARVO-200 is a 2" simple-action aluminum air vent with a durable epoxy orange coating that provides an extra layer of corrosion protection beyond standard aluminum. It automatically expels trapped air during system startup and admits air during shutdown, preventing water hammer, air locks, and vacuum-induced pipe collapse.
Key Features & Benefits
- Epoxy orange coating — adds corrosion resistance beyond bare aluminum, extending service life in chemically treated water or harsh environments
- Dual-function operation — expels air during filling and admits air during drainage to prevent vacuum collapse
- 1.9" clear opening diameter — large orifice allows rapid air expulsion for faster system startup
- Cast aluminum body — lightweight at 1.65 lbs for easy installation on risers and high points
- Synthetic rubber seal — ensures positive sealing even at low head applications (7 PSI sealing pressure)
- Simple, reliable design — no complex moving parts means trouble-free performance with minimal maintenance
Why Choose Epoxy Coated?
The epoxy orange finish provides additional protection against corrosion when the air vent is exposed to chemically treated irrigation water, fertilizer injection systems, or particularly aggressive environmental conditions. It also makes the valve easy to identify in the field.
