Piston check valve
The KEHUA catalogue uses piston check for this series. Request the piston, guide and any spring arrangement before evaluating opening response, pressure loss and orientation; the name does not establish an axial or nozzle design.
About the piston check valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.

What should a piston check valve quotation identify?
Request the piston and guide section drawing, any spring details and the approved installation orientation for a piston check valve quotation. Provide fluid cleanliness, flow range and start-stop or reversal cases for pressure-loss and response review. Keep the catalogue identity: do not treat the valve as an axial or nozzle design without model evidence.
