Description

The D-016, D-100 combination air valves for high pressure have the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Product Features

  • 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.
  • Special orifice seat design: combination of bronze and E.P.D.M. rubber assures long-term maintenance-free operation.
  • Available in flange sizes: 2" – 8"
  • The 2” valve is also available with a threaded BSP or NPT connection.
  • These valves are manufactured with flanged ends to meet any requested standard.

  • Air Release Component:
    • Body and cover made of Cast Steel ASTM A216 WCB.
    • All operating parts are made of specially selected corrosion- resistant polymer materials.

Application Range

  • Working pressure range:
    • D-016: 0.2 - 64 bar
    • D-100: 0.2 – 100 bar
  • Maximum operating temperature: 60°C.
  • Maximum intermittent temperature: 90° C.
