Manual control valve f500

The round manually adjustable dampers for ducts are mechanical devices that provide precise control of airflow in ventilation, air conditioning, and heating (HVAC) systems. They are designed to enable optimal air distribution across different zones in a building, offering a simplified but effective way to regulate airflow.

Construction and Operating Principle:

The manually adjustable damper for a round duct consists of a casing, inside which there is a regulating mechanism - a blade that moves via a round handle with a stepped locking mechanism placed on the outside of the casing. The damper is designed to allow the operator to increase or decrease the airflow by adjusting the degree of opening or closing of the blade.

Technical Specifications:

• Materials: The casing and blade are made of high-quality galvanized steel, and the regulating mechanism is made of nylon (synthetic polymer), ensuring durability and corrosion resistance.
• Operating Temperature: Round dampers typically withstand temperatures up to 80°C without compromising the integrity of the casing or the regulating mechanism, making them suitable for most HVAC systems.
• Adjustable Range: The damper opening can be adjusted over a wide range, from fully open to fully closed.
• Airflow Speed: They provide effective control of airflow at speeds up to 20 m/s, making them suitable for both low and high flow rates.
• Sealing: This model of the regulating damper does not have airtight seals on the blade and is not suitable for ventilation systems requiring airtightness. For full airtightness, we recommend using dampers with rubber or silicone seals.
• Options: Dampers with a diameter over Ø125 can be made with a double-reversed end or silicone seal.

Advantages:

• Easy Adjustment: Provides easy adjustment of airflow in ventilation systems.
• Maintenance-Free: Due to their simplified mechanical design, manual dampers require no maintenance, making them reliable in the long term.
• Installation: The diameter of the dampers is matched to that of the ducts, making installation incredibly easy by simply inserting the damper into the duct.

Round manually adjustable dampers are an essential component for any HVAC system, providing an easy and effective way to control airflow. They offer a cost-effective solution for projects where automated dampers are not required, while ensuring long-lasting and efficient operation.
