Double Pendulum Valve Nedir?

Double Pendulum Valveis a double-flap discharge mechanism that transfers dust, granules or particulate material accumulated in dust collection and material discharge systems to downstream equipment in a controlled manner.

The system works on the sequential operation principle of two pendulum valves. While one valve receives the material, the other keeps the line closed. This maintains material flow while reducing air leakage and pressure loss.

How Does a Double Pendulum Valve Work?

When material accumulates in the upper chamber, the first valve opens and transfers dust or granules to the intermediate chamber. Meanwhile, the lower valve remains closed to help maintain the system’s air balance.

The first valve then closes and the lower valve opens, transferring material to the next station, bag-filling line, conveyor, hopper outlet or discharge point. This cycle provides controlled discharge while supporting sealing performance.

Applications

• Industrial dust collection systems
• Bag filter and cartridge filter units
• Cyclone and centrifugal separator systems
• Discharge points beneath silos, hoppers and vessels
• Big Bag filling stations
• Screw conveyor feed lines
• Pneumatic conveying systems
• Chemical, food, cement, pharmaceutical and metal industries
• Processes involving the transfer of dust, granules and particulate materials

System Advantages

• Makes material discharge controlled and consistent.
• Helps reduce air leakage because only one valve remains open at a time.
• Contributes to maintaining process pressure balance beneath filters, silos and hoppers.
• Provides an effective discharge solution for systems operating under positive or negative pressure.
• Ensures efficient operation in processes requiring continuous material flow.
• Can be manufactured with a durable design for applications involving abrasive and heavy dust loads.
• Can be engineered to allow easy maintenance and service access.

Selection Criteria

Double Pendulum Valve When selecting, material density, particle size, discharge capacity, operating pressure, system temperature, dust characteristics, chamber geometry, connection dimensions and operating frequency must be assessed together.

In addition, for abrasive dust, housing material, flap construction, sealing elements, the need for motorised or pneumatic actuation, maintenance access and process-safety details must be properly specified. An incorrectly selected valve can cause air leakage, material build-up or irregular discharge.

Basic Components

• Upper valve flap
• Lower valve flap
• Intermediate chamber or transfer housing
• Durable steel housing construction
• Connection flanges
• Sealing elements
• Mechanical, pneumatic or motorised actuation system
• Level sensor and control connection as required
• Maintenance and inspection covers
