Size ranges describe the catalogue family and do not establish current stock. Confirm the selected variant's dimensional drawing, connection standard and available configuration.
Materials and Pressure-Temperature Selection
The catalogue lists CF8M / EN 1.4408 as the standard body material and R-TFE as the standard seat, with other body and seat options. Confirm the exact supplied material grade and sealing configuration.
Allowable pressure depends on size, port, material, seat and temperature. Use the selected configuration's pressure-temperature chart rather than applying a single rating to the whole series.
Fire Safe and Documentation Requirements
The catalogue identifies the standard valve as a non-fire-safe design and offers an optional fire-safe configuration. Where fire-safe performance or a specific approval is required, state it explicitly and obtain documentation covering the actual model and configuration supplied.
Actuation and Enquiry
For actuator selection, confirm valve torque, mounting pattern, shaft dimensions and the required operating duty. Send the size, full or reduced port, end connections, fluid, pressure, temperature, materials, operating method and quantity. Include all required approvals and inspection documents.
