1. Quick Overview
Exporting industrial valves to South America requires more than competitive pricing—it demands reliability, adaptability, and technical precision. In this customer case, Vcore Valve, based in Xiamen, China, successfully delivered manual knife gate valves to Brazil for use across multiple industrial sectors, proving strong performance under harsh working conditions.
2. Opening Scenario: A Practical Request from Brazil
“We need knife gate valves that can handle slurry, fibres, and frequent operation—delivery time is tight.”
This was the starting point when a Brazilian customer contacted Vcore Valve for a reliable solution suitable for mining and wastewater facilities.
3. Customer Pain Points
Severe Media Conditions
The system involved slurry, solids, and fibrous materials that often cause blockage.
Unstable Quality from Previous Suppliers
Earlier imported valves suffered from leakage and premature wear.
Tight Project Timeline
The valves had to be manufactured, tested, and shipped within a strict deadline.
4. Vcore Valve’s Solutions and Recommendations
Optimised Knife Gate Valve Structure
A manual knife gate valve with a straight-through bore minimised clogging.
Material Selection for Durability
Materials were selected to resist abrasion and corrosion in aggressive media.
Comprehensive Quality Inspection
Each valve passed pressure, sealing, and operational tests before shipment.
5. Project Background and Valve Specifications
The valves were supplied for multiple Brazilian industrial facilities, including:
-
Mining slurry pipelines
-
Wastewater treatment plants
-
Industrial discharge systems
Main specifications:
-
Manual handwheel operation
-
Rising stem design
-
Replaceable resilient seat
-
DN80–DN300 sizes
-
Flanged end connections
6. Case Analysis: Why Manual Knife Gate Valves Were Selected
Compared with other valve types, manual knife gate valves offer superior performance in solid-laden media.
Key Advantages
-
Minimal pressure drop
-
Reliable shut-off
-
Simple maintenance structure
These benefits made them the most practical choice for the project.
7. Engineering Data and Performance Comparison
| Valve Type | Slurry Handling | Maintenance | Cost Efficiency |
|---|---|---|---|
| Butterfly Valve | Medium | High | Medium |
| Ball Valve | Low | Medium | Low |
| Knife Gate Valve | High | Low | High |
Field experience shows knife gate valves reduce blockage risk by over 40% in slurry systems.
8. Manufacturing and Quality Control in Xiamen
At Vcore Valve’s Xiamen facility, production followed a strict process:
-
Raw material inspection
-
Precision machining
-
Controlled assembly
-
