Column Valve
The Column Valve is a component used to adjust the air volume and pressure control between branches in ventilation installations. This valve offers the possibility to adjust the damper blades with a manual lever or damper motor, which gives users the flexibility to adjust the air flow and pressure according to their needs. This feature of the column damper supports the efficient and effective operation of ventilation systems.
General Features
- X It is used to adjust the air quantity and pressure control between branches in ventilation installations.
- X Damper blade adjustment is made by manual lever or damper motor.
