A damper is a valve that stops or regulates (controlling) the flow of air inside a duct. It can be operated manually or automatically. It is made by a single flap or multiple flap (louvers) depending on damper size and construction. It can be operated in full open, full close and position controlled by the positioner. This can also operate under positive or negative pressure conditions.
Damper sizes and shape depend on process requirement and typically are of circular, square and rectangular type. We have an expertise to handle class IV leakage.
Types of Valve:
- Manual damper
- Electropneumatic Damper
- Motorised Damper
Material of Construction available:
- Stainless steel
- Mild steel
- Any special grade of steel depending on application
1. Manual Damper:Manual dampers are normally open and close type damper used for controlling the flow. Manual damper is used for small size or small torque application.
2. Electropneumatic Damper: The damper is operated electro
pneumatically. The damper flap can be operated by pneumatic cylinder or actuator along with solenoid valve. It can be full open or full closed operation. To maintain a flap position an actuator is used which is responsible for movement and control. The accuracy level is remarkably high. Also, the operation speed is extremely high compared to manual damper. It can be used in small size to big size application.
3. Motorised Damper: The damper flap can be operated by electric motor. It can be full open or full closed operation. Electric motor is a component of a machine that is responsible for moving and controlling a mechanism to maintain the plate position. The accuracy level is high. Operation speed is high compared to a manual damper. It can be used in small size to big size application.
