APPLICATIONS
The medium and operating duty change what a valve must withstand. Use the application pages to identify relevant valve families and the data needed for a technical discussion.
INDUSTRY ROUTES
Move from the process to the product.
Each route connects common selection questions with the relevant parts of the DQSV catalogue.
01 · CHEMICAL PROCESSINGMaterial compatibility and process isolationStart with fluid composition, concentration, pressure and temperature.
02 · METALLURGY & MININGSlurry transport and abrasive serviceDescribe solids content, particle size, cycling and maintenance needs.
03 · OIL & GASControl, isolation and shutdown dutiesDefine the duty, connection, actuation and project requirements.
SELECTION INPUTS
Use the actual duty, not the industry label.
Two plants in the same industry can require different valve structures and materials. Share the operating envelope and project specification before fixing the configuration.
- Medium
- Composition, concentration, solids and corrosion conditions
- Operating range
- Design and normal pressure, temperature and flow
- Mechanical interface
- Line size, connection standard, orientation and space
- Operation
- Manual or powered actuation, signal and fail position
- Project handoff
- Tests, drawings, records, identification and packaging
