Single Chamber – Double Function

Single Chamber – Double Function

Corvalve’s Single Chamber Double Function Air Valve is a testament to superior engineering, harmonizing efficient air discharge and intake in a singular chamber system. Our valve ensures precision control, bolstering system efficiency while minimizing premature closure. This product offers a robust and reliable solution, ensuring optimal operational performance in various industrial applications.


Single Chamber Air Valves are designed to perform two functions:

  1. Venting of air on the start-up of the system, while pipelines are filled.
  2. Intake of air on shut-off of the system, while pipelines are drained.

Note: This valve is not suitable for discharging pressurized air pockets while the system is operating. Please refer to other Corvalve Air Valve models for such a feature.
