Before selecting a part
- Read the valve manufacturer and full model, including suffixes.
- Compare top fastening, flow control, size and connection.
- Check the requested part: diaphragm, bonnet and full repair kit are separate assemblies.
- Stop when markings conflict or a required generation is unknown.
Unknown old style vs HP means UNRESOLVED. Never install an HP diaphragm in an old-style body or an old-style diaphragm in HP.
