What Are Diaphragm Valves?

Diaphragm Valves & Repair Kits

In dust collection, the purpose of a diaphragm valve is to regulate the airflow through the filters to optimize cleaning. Diaphragm valves create a pulse of air which dislodges any dirt and dust on the outside of a filter so that debris can be collected and discarded. 

These valves are used on many different types of dust collection systems and in industries and applications. Typical uses for them include: 

  • Mining
  • Chemical processing facilities
  • Woodworking shops
  • Food processing plants
  • Pharmaceutical manufacturing systems
  • Power generation stations
  • Cement plants
  • Recycling plants

How Do Diaphragm Valves Work?

Diaphragm valves have simple design and operating principles. Their key components are a diaphragm and an actuator. The diaphragm is what gives these valves their name. It is a thin, flexible membrane used to open and close the valve. The actuator is what controls the diaphragm. In the open valve position, it allows the diaphragm to stay out of the valve passageway, enabling air to flow through the valve. In the closed valve position, it pushes the diaphragm into the valve passageway, blocking air from flowing through the valve.
