Butterfly Damper Valve for Airflow Shut-Off & Industrial Dust Control
(Katup Redaman Kupu-kupu untuk Penutupan Aliran Udara & Pengendalian Debu Industri)
Reliable butterfly damper valve for airflow regulation, dust control, and industrial ventilation systems
Overview
The Butterfly Damper Valve is designed for quick shut-off and airflow control in industrial ventilation, dust extraction, and pneumatic conveying systems.
Its single-blade design allows fast response, low leakage, and stable performance, making it ideal for baghouse systems, cyclone separators, ducting networks, material feeding lines, and negative-pressure conveying.
This type of damper provides reliable sealing with simple operation and is widely used across cement, grain, chemical, fertilizer, mining, and bulk material handling industries.

FAQs About Butterfly Damper Valves
What is a butterfly damper valve used for?
A butterfly damper valve is used to control, regulate, or shut off airflow in industrial ventilation, dust collection, and pneumatic conveying systems. It is commonly installed in ducting, baghouse inlets/outlets, cyclones, and material transfer points.
What is the difference between a butterfly damper and a butterfly valve?
A butterfly damper is designed for airflow and gas control, typically operating at low pressure, while a butterfly valve is mainly used for liquid flow control under higher pressure conditions. Butterfly dampers focus on sealing performance, low pressure loss, and dust handling.
Can butterfly damper valves be automated?
Yes. Butterfly damper valves can be equipped with electric, pneumatic, or motorized actuators, allowing integration with PLC control systems and centralized automation for industrial airflow management.
Are butterfly dampers suitable for dust collector systems?
Absolutely. Butterfly dampers are widely used in dust collection systems, including bag filters and cyclones, for airflow isolation, balancing, and emergency shut-off in dusty and abrasive environments.
What materials are available for industrial butterfly damper valves?
Industrial butterfly damper valves are typically manufactured from carbon steel or stainless steel, with optional high-temperature, corrosion-resistant, or abrasion-resistant designs based on application requirements.
