Bore Type Dimensional Configurations
We offer three primary bore types, each with specific dimensional characteristics:
Full Bore (Full Opening)
- Bore diameter equals pipe inner diameter
- Minimal pressure drop across valve
- Ideal for: slurry, pigging operations, high-flow requirements
- TypicalCv values: 1.2 times pipe diameter squared
Reduced Bore (Standard Bore)
- Bore diameter typically one size smaller than pipe
- Standard dimensions reduce manufacturing costs
- Ideal for: general service, on/off applications
- Cv values: approximately 70-80% of full bore equivalents
Vented Bore (Venturi)
- Special contour design maintains near-full flow
- Unique dimensional profile for erosion resistance
- Ideal for: abrasive media, mineral processing
- Cv values: 90-95% of full bore performance
