D-025 L | Combination Air Valve for Wastewater

Description

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.
• Combines the features of both an air & vacuum valve and an air release valve.
• Triple function:
  • Air & vacuum component discharges large volumes of air during filling of the system.
  • Air & vacuum component admits large volumes of air during drainage and at water column separation.
  • The air release component releases entrapped air in pressurized systems.
