Flow control lives or dies by precision. JOC produces bodies, impellers, casings, seats, stems, and actuated assemblies for water, chemical, power, and process plants. As a China manufacturer and supplier, we recommend the right path—investment casting for complex geometries, forging for strength, and CNC finishing for sealing accuracy.

What is critical in pump & valve parts?
Flatness, concentricity, and surface finish where seals meet metal. We control porosity with process selection, then lap and test to ensure bubble-tight performance. For pumps, balance is key; we dynamically balance rotating elements to avoid vibration.
How to choose materials?
Base it on media and temperature: duplex for chloride stress, bronze for seawater, carbon steel for general duty with appropriate coatings. We’ll lock in the spec with certificates and testing. **Let’s optimize your flow—**connect via Contact Us.
