Check Valves
Wafer check valve
Wafer identifies a check-valve body fitted between pipe flanges, not its internal closing mechanism. Identify the actual disc design on a section drawing and check opening clearance against the adjoining pipe and fittings.
About the wafer check valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.

What must a wafer check valve RFQ confirm?
A wafer check valve RFQ should confirm the mating flange drilling and facing, pipe bore, face-to-face length and opening clearance, then identify the actual closing mechanism. Request its section drawing, permitted orientation and seat-test requirements. A wafer body is not automatically dual plate and does not establish spring details or closing response.
Related procurement checks: dual plate check valve series; check valve selection guide; Check the mating connection specification.
Compare construction choices in this valve family- Specify mating flange standard, drilling and required face-to-face length.
- Request the section drawing; a wafer body is not automatically a dual-plate mechanism.
- Check mounting orientation, travel clearance, closing response and seat acceptance.
- Attach the flange drilling/facing, pipe bore and face-to-face requirements with mounting orientation and opening space. Provide fluid, flow range, pressure, temperature and available reversal data. Include quantity, destination, requested date and drawing/material/test records; ask the offer to state the actual mechanism and dimensional deviations.
