General
After receiving the customer’s drawing, we reviewed the material specification, dimensions, tolerances, thread requirements, and manufacturing feasibility.
The parts were produced by centrifugal casting and then CNC machined to achieve the required dimensions and thread accuracy.
Project Overview
This project involved the production of custom valve stem nuts for industrial valve equipment.
The component was manufactured using centrifugal casting followed by CNC machining to ensure high strength and precise thread dimensions.
For custom bronze bushings, sleeves, rings, nuts, and other cylindrical copper-alloy components requiring dense material structure and subsequent machining, explore our centrifugal cast bronze components manufacturing capabilities.
The material used was UNS C92200 bronze according to ASTM B584, which provides excellent wear resistance, corrosion resistance, and long service life in valve applications.
Manufacturing Process
The production process included:
- centrifugal casting for dense bronze structure
- rough machining and thread processing
- dimensional inspection and quality control
This manufacturing method ensures stable mechanical properties and reliable performance for valve components used in industrial fluid control systems.

Material
The material is UNS-92200, it needs to meet the requirement of standard ASTM B584.
We need to make sure that our material’s chemical composition and mechanical properties 100% meet the requirements of this standard.
We carefully checked the standard and determined the material composition and mechanical property requirements here.

We marked the number of each size inside the drawing, which corresponds to each measured photo and certificate.
Packing
The finished parts were securely packed in an export-standard plywood case suitable for international shipment.
