Wafer V-port ball valve
A compact wafer assembly for process control where installation length and weight matter.

Compact installations, pulp stock and process liquids
The wafer body fits between compatible pipe flanges. The 2023 flyer lists a metal-seat configuration and manufacturer-standard face-to-face dimensions; interchangeability must be checked against the drawing.

What to confirm before ordering
- Verify bolt lengths, flange bore and segment clearance before replacing an existing wafer valve.
- Check the direction arrow and permitted pressure direction.
- Allow space for actuator maintenance and positioner access.
One coordinated supply scope
- Valve body, seat, segment and shaft specified against the medium and operating envelope.
- Actuator sized for the required torque and failure response.
- Controls and feedback selected for the plant interface.
- Inspection and documentation identified in the quotation.
