Dump Valve
The Clyde Dump Valve is designed to allow multiple hoppers or silos to be fed in series from a single pneumatic conveying pipeline.

The Clyde Dump Valve is designed to allow multiple hoppers or silos to be fed in series from a single pneumatic conveying pipeline. Operating in either "dump" or "by-pass" mode, the valve enables the control system to selectively discharge material into a chosen vessel while allowing the pipeline flow to continue to downstream delivery points.
One Dump Valve is installed at each delivery point along the conveying line, with the final discharge typically terminating in a Terminal Box. The automatic control system determines whether the valve opens to discharge material into the silo or remains closed, allowing the material to continue along the pipeline to the next destination.
This configuration provides a flexible, efficient method for distributing bulk materials to multiple storage silos via a single conveying line.
Key Features
- Low Profile Design: Enables tangential entry into the silo, keeping the conveying pipeline low and reducing the need for support structures.
- Guaranteed Actuation: Heavy-duty pneumatic air cylinder ensures reliable valve positioning and operation.
- Replaceable Wear Parts: Deflector plate can be replaced when worn, extending valve service life.
- Nominal Bore Sizes: Available in sizes DN50 to DN500.
- Heavy-Duty Construction: Internals feature a cast-iron deflector plate for durability.
These features ensure the Dump Valve provides reliable performance in demanding pneumatic conveying environments.
Key Benefits
- Low Installation Height: Tangential entry simplifies silo inspection hatch access and reduces structural requirements.
- Extremely Reliable Operation: Robust cast iron internals and heavy-duty pneumatic actuation provide long service life.
- Fully Shop Assembled: Pre-piped to the pneumatic control panel in the factory, reducing site installation time.
- Multi-Line Configuration: A compact design allows multiple Dump Valves to be installed on a single silo roof.
Typical System Arrangement
In a typical multi-silo pneumatic conveying system:
- A single conveying pipeline: runs past several storage silos.
- A Dump Valve: is installed at each silo connection.
- The control system: selects which silo receives material.
- Remaining silos: are automatically by-passed.
This arrangement enables flexible material distribution without complex pipeline switching systems.
Custom Features:
- Deflector Plate Linings: Available with Ni-Hard or ceramic linings for abrasive materials.
- Positional Indication: Limit switches or proximity sensors available for valve position feedback to the control system.
