Valve damper DN 65 IDMAR APF065FAF3500E cast iron 150°

The IDMAR valve damper DN 65 APF065FAF3500E is a cast-iron rotary damper with a 150° rotation range, engineered for flow regulation and shut-off in ventilation, ducting and industrial pipelines. This DN 65 unit provides stable throttling performance and a compact design that fits standard pipe connections for HVAC and process installations where a durable metal damper is required.

Advantages

Constructed from cast iron, the damper offers mechanical strength and corrosion resistance suitable for many industrial and commercial ventilation environments. The 150° rotation allows precise intermediate positioning and reliable closure for flow control. The unit’s compact DN 65 diameter and standardized connections simplify integration into existing ductwork and piping systems. Designed for routine operation, it provides consistent performance with minimal maintenance.

Suitable for

• HVAC ventilation ducts and air handling systems
• Industrial process pipelines requiring flow throttling
• Commercial and light-industrial exhaust and supply systems
• Retrofit projects where a robust cast-iron damper is needed

Key specifications

• Nominal diameter: DN 65
• Body material: cast iron
• Rotation range: 150°
• Function: flow regulation and shut-off (rotary damper)
• Typical applications: ventilation, ducting, process piping

How to use

Install the valve damper inline with matching DN 65 duct or pipe connections following local mechanical and safety codes. Mount the actuator or manual handle on the designed shaft interface, ensuring secure coupling and correct alignment. Adjust the rotation stops or actuator travel to achieve the required open and closed positions within the 150° range. Verify sealing and operation by cycling the damper several times and checking for smooth movement and absence of leaks before commissioning the system.

Usage recommendations

Use the cast-iron damper in dry or moderately humid environments and avoid exposure to aggressive chemical atmospheres unless additional protection is applied. For reliable long-term operation, perform periodic inspections of the shaft, seals and mounting fasteners, and lubricate moving parts as specified by site maintenance practices. When used in HVAC systems, coordinate damper positioning with control actuators and building automation to ensure accurate airflow regulation.
