What should be confirmed before ordering?

Confirm the model, DN size, body/gate material, seat material, pressure class, flange standard, medium and actuator option against the selected catalog drawing.

Does one series cover all materials and sizes?

No. Materials, dimensions and pressure limits depend on the exact model suffix and DN size shown in the catalog material and dimension tables.

Can an actuator be supplied?

Manual, pneumatic, electric and other actuation options are catalog-dependent. Confirm the actuator type, control mode and mounting details for the final valve selection.

Which documents should be requested?

Request the current dimensional drawing, material list, inspection requirement and final technical confirmation for the selected model and size.
