S-021 | Automatic Air Release Valve for Reclaimed and Non-Potable Water
PN 10 – DN 25-50
The S-021 Automatic Air Release Valve is specially designed to operate with reclaimed and non-potable water. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
- Specially intended to operate with liquids carrying solid particles such as reclaimed water and effluents
- Unique "air gap" design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
- The air release component releases entrapped air in pressurized systems.
- Available 25mm – 50mm (1"& 2") with a threaded BSP or NPT connection.
- Flexible rolling seal provides smooth positive opening, closing, and leak-free sealing.
- Available also in flange sizes: 25mm – 50mm (1"- 2").
- These valves are manufactured with flanged ends to meet any requested standard.
