Cast Nuts

Mingxin introduction includes valve-related cast products within its broader foundry range; this entry does not establish an assembled-valve model.

Water-pump components are explicitly named in the company introduction, with the actual part defined by the enquiry drawing.

Railway components form another published company foundry group, separate from the pump and valve component range.

Mingxin publishes a named gland or cover component; the listing does not identify a universal valve or pump application.

Brackets appear as a separate named product in the company own display; request the actual mounting and loading information for the intended assembly.
