Description

The S-020 and S-022 Automatic Air Release Valves are specially designed to operate with liquids carrying solid particles such as wastewater and effluent. The valves release accumulated air (gases) from the system while under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

Product Features

  • Specially designed to operate with liquids carrying solid particles such as wastewater and effluents.
  • Unique "air gap" design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
  • Function:
    • The air release component releases entrapped air in pressurized systems.
  • Available in flange sizes: 50mm – 100mm (2"- 4").
  • The 50mm valve is also available with a threaded BSP or NPT connection. These valves are manufactured with flanged ends to meet any requested standard.
