The Clyde Dome Switch Valve is designed for reliable routing of bulk materials within pneumatic conveying systems. By incorporating Clyde's proven Dome Valve technology, the switch valve provides a pressure-tight and highly dependable solution for diverting material flow between conveying pipelines.
The valve combines simple, robust mechanical design with fast pneumatic actuation, delivering long-term reliability even in difficult applications involving abrasive, cohesive, or high-temperature materials.
Because the sealing arrangement is based on the proven inflatable Dome Valve seal, the switch valve ensures zero leakage, minimal wear, and exceptional availability across a wide range of industrial processes.
The operating efficiency of Clyde Pneumatic Conveying systems relies heavily on dependable pipeline routing equipment, and the Dome Switch Valve provides the same proven reliability as the standard Dome Valve technology.
Key Features
- Inflatable Sealing Mechanism: Unique pressure-tight sealing achieved using an inflatable seal that inflates on valve closure and deflates when opening.
- Full Bore Flow: Unrestricted material flow through the valve, minimising pressure loss and wear.
- Pneumatic Actuation: Fast-acting heavy-duty pneumatic actuation using a combination of cylinder and vane actuators.
- Nominal Sizes: Available in standard sizes from 50 mm to 400 mm.
- Temperature Range: Suitable for operating temperatures from –20°C up to 450°C.
These features enable the Dome Switch Valve to route the pipeline while reliably maintaining conveying system performance.
Benefits
- Zero Leakage: Pressure-tight sealing capable of handling pressures up to 30 barg.
- Extremely Reliable: Proven design using robust and well-tested components across thousands of installations.
- High Availability: Over 3,000,000 cycles between major overhauls and 1,000,000 cycles between seal replacements.
- Cuts Through Material: Capable of closing against moving or static columns of bulk material.
These capabilities make the Dome Switch Valve ideal for high-reliability routing applications in dense-phase conveying systems.
Custom Features
- Dome Coatings: Electro-nickel plating or polymer coatings available for handling abrasive or cohesive materials.
- High Temperature Options: Water-cooling arrangements allow operation above 200°C up to 450°C.
- High-Pressure Designs: Standard valve rated to 7 barg (10 barg design), with up to 30 barg available for specialised applications.
These optional features allow the Dome Switch Valve to be configured for demanding industrial environments.
