Corrosion-Resistant Valves for Seawater Chemical Processing Systems

Introduction

FLOWX is proud to provide cutting-edge corrosion-resistant valves for extreme seawater chemical processing systems. Recently, FLOWX prepared 3,321 custom valves for a groundbreaking seawater potassium extraction project in Fujian, China. These valves play a crucial role in ensuring safe, reliable, and precise fluid control throughout the project.
 

Project Overview – 100,000 Ton/Year Seawater Potassium Extraction in Fujian

Situated at the core of Fujian’s marine economy and strategic mineral development, the 10,000-ton per year seawater potassium extraction project is a world-first initiative using the zeolite ion-sieve physical process. FLOWX is the strategic valve supplier, delivering 3,321 valves spanning hard-sealed butterfly valves, ball valves, and control valves, with sizes ranging from DN15 to DN500. This comprehensive valve matrix supports both large-scale seawater intake and precise process control across the production line.

Operating Condition Challenges – Extreme Environment Fluid Control

The project operates under highly demanding conditions, including high-salinity seawater, strong corrosiveness, and large fluctuations in production pressure. These conditions require valves that provide maximum corrosion resistance, reliability, and accurate control, ensuring smooth operation even in extreme environments.
 

FLOWX as Strategic Valve Supplier

FLOWX was selected as the strategic supplier after multiple evaluations. With extensive experience in extreme-condition applications, FLOWX delivered customized valve solutions tailored to meet the full spectrum of process requirements, earning long-term trust from the project owner.

Customized Valve Solutions – Full-Process Valve Matrix

Valve Types and Specifications

The custom valve matrix includes:

• Hard-sealed butterfly valves

• Ball valves

• Control valves

Valve sizes range from DN15–DN500, supporting both large-volume seawater intake and precise flow regulation throughout the production process.

Material and Design Advantages

The valves are constructed from special corrosion-resistant alloys and feature reinforced sealing structures and precision-engineered valve seats. They are designed for high pressure tolerance, impact resistance, minimal wear, and extended service life. These attributes deliver stable, long-term operation while minimizing maintenance and unplanned downtime.

On-Site Performance – Reliable and Stable Operation

From earlier bulk deliveries to the latest shipment of 3,321 valves, FLOWX has demonstrated zero-fault performance under extreme seawater conditions. This reliability has solidified client trust and established FLOWX as a benchmark for extreme-condition industrial valves.

Future Outlook – Scaling Up Seawater Potassium Production

The project plans to scale up to 1,000,000 tons per year, and FLOWX will continue to provide full-process valve coverage. With technological innovation and strict quality control, FLOWX supports the sustainable development of Fujian’s seawater potassium industry, strengthening its global leadership position.
