Precision in a Caustic Environment: Delivering a Reliable Alternative for Electrolyzer Flow Control
The heart of the green hydrogen economy beats in the electrolyzer, where precise control of aggressive chemicals like concentrated sodium hydroxide (NaOH) at high temperatures is non-negotiable. For years, this critical application has relied heavily on specialized imported valves.
HANDA is changing that narrative. We've engineered a high-performance control valve specifically built to master the challenges of electrolyzer feedstock management.
Why This Valve is a Game-Changer for Engineers and Operators:

✔️ Built for the Application: Designed to handle concentrated NaOH at continuous temperatures up to 85°C, matching the harsh realities of electrolyzer operation.
✔️ Material Superiority: Constructed from Hastelloy C-276, one of the most corrosion-resistant nickel-molybdenum-chromium alloys available. It stands up to pitting and stress corrosion cracking where standard stainless steels fail.
✔️ Focus on Precision: Beyond durability, it delivers accurate and stable flow control, a key factor for maintaining electrolyzer efficiency, product purity, and safe operating parameters.
✔️ Strategic Supply Chain Solution: It serves as a direct, high-quality alternative to Japanese imports, offering significant advantages in cost control, lead time reduction, and supply chain resilience.
This valve represents more than just a component; it's a commitment to supporting the core infrastructure of the new energy sector with reliable, innovative, and accessible engineering solutions.

Building Partnerships on Reliability: HANDA Pinch Valves Earn Repeat Business Building Partnerships on Reliability: HANDA Pinch Valves Earn Repeat Business in the DRC
In the mining industry, especially in demanding environments, equipment performance is critically measured by its reliability and impact on operational uptime. A single order is a trial; repeat business is the true testament of trust.
We are proud to highlight an ongoing partnership with a significant mining project in the Democratic Republic of the Congo. Their initial confidence led to a major order of 280+ HANDA Pinch Valves, including:
• Pneumatic valves with handwheel (SS body) for critical automated lines with manual backup.
• A full range of manual pinch valves (DN50 to DN400) for various slurry control points.
The Outcome: Performance that Builds Loyalty.
The valves delivered reliable service in handling abrasive slurries, meeting the client's stringent operational demands. This successful deployment did not just end with the initial purchase. It established a foundation of trust, leading to a scheduled, annual procurement plan for spare rubber sleeves (repair kits).
This transition from a project supplier to a long-term maintenance partner underscores a key HANDA principle: we provide solutions that reduce your total cost of ownership. The durable valve body lasts for decades, while only the wearable sleeve needs periodic replacement—a simple, cost-effective maintenance model.
Why Pinch Valves for Mining & Slurry?
✔️ Excellent abrasion resistance (wear is limited to the sleeve).
✔️ Full-bore design prevents clogging.
✔️ Tight shut-off even with suspended solids.
✔️ Easy and fast sleeve replacement minimizes downtime.
This case exemplifies how reliable performance in the field translates into lasting partnerships. If your operations involve abrasive, corrosive, or slurry media, let's discuss how we can build a reliable solution—and a lasting relationship—for you.

Eliminate Downtime in PSA Nitrogen Generation: The Million-Cycle Valve Solution
For plant managers and engineers, unscheduled downtime in a Pressure Swing Adsorption (PSA) nitrogen plant is more than an inconvenience—it directly impacts production, purity guarantees, and the bottom line. The core of this reliability challenge often lies in the valve packages controlling the rapid adsorption/regeneration cycles.
Introducing a solution engineered for endurance: The HANDA High-Performance Double Eccentric Butterfly Valve, integrated with a Premium Italian Single-Acting Pneumatic Actuator.
Why is this combination critical for PSA success?
✔️ Valve Design: The double eccentric (double offset) geometry ensures the metal sealing surfaces completely disengage during operation. This eliminates wear, providing bubble-tight shut-off and enabling a lifespan of over 1 million cycles without leakage.
✔️ Actuator Performance: The matching Italian single-acting actuator is selected for its fast response, robust construction, and reliable sealing, capable of matching the valve's million-cycle performance under continuous switching duty.
✔️ System Synergy: Together, they form a reliable unit built for the rapid, repeated switching fundamental to PSA processes. This translates to sustained nitrogen purity, reduced maintenance costs, and maximized system availability.
Upgrade your critical PSA valves from a maintenance liability to a reliability asset.

Case Study: Enabling Reliable Control in a World-Scale 1.1 MTPA Pulp & Paper Mill
The pulp and paper industry presents some of the most challenging conditions for control valves: abrasive fibrous slurries, clogging tendencies, and corrosive chemical dosing. Valve failure here directly impacts production consistency, quality, and operational efficiency.
We are proud to share that HANDA Pneumatic Control V-Port Ball Valves have been successfully deployed in the stock preparation and chemical dosing systems of a major 1.1 Million Ton Per Annum integrated pulp and paper mill.
The Challenge:
The mill needed valves that could provide precise, repeatable control of pulp stock and additives while enduring the abrasive, fibrous nature of the media without clogging or rapid wear.

The HANDA Solution:
Our V-Port Ball Valve was the ideal fit due to its:

✔ Superior Abrasion Resistance: Robust construction and optimized design minimize erosion from solids in the slurry.
✔ Anti-Clogging Design: The V-port ball and full-bore capability prevent fiber accumulation and blockages common in other valve types.
✔ Excellent Control Performance: Delivers precise modulating control with high rangeability, essential for maintaining consistent stock quality.
✔ Proven Durability: Engineered for high-cycle, low-maintenance operation in 24/7 continuous processes.

This installation underscores our commitment to providing not just products, but reliable process solutions for demanding industries. By understanding the unique challenges of pulp and paper production, we deliver valves that enhance operational reliability and reduce total cost of ownership.

Solving the Achilles' Heel of Electrolyzer Brine Control: Moving Beyond Fragile Diaphragm Valves
In hydrogen production, chlor-alkali, and other electrochemical processes, precise brine (salt solution) flow control is critical for efficiency and safety. For years, this task has often fallen to imported diaphragm valves, which bring a known weakness: the elastomer diaphragm itself.
The Problem: These diaphragms are prone to fatigue, cracking, and rupture due to constant actuation cycles and exposure to corrosive, saturated brine. This leads to unplanned shutdowns, maintenance costs, and production losses.
The HANDA Solution: We’ve engineered a robust alternative. Our Electrolyzer Brine Flow Control Valve (DN65, DN80) replaces the vulnerable diaphragm mechanism with a durable PTFE-lined, WCB body design.
Key Advantages for Your Plant:
✅ Unmatched Reliability: Eliminates the primary failure mode. No more diaphragm changes, just consistent operation.
✅ Precision Maintained: Provides the fine flow modulation essential for stable electrolyzer performance, matching the control accuracy of the valves it replaces.
✅ Corrosion-Resistant: The PTFE lining offers excellent protection against harsh brine chemistry, ensuring a long service life.
✅ Cost-Effective Upgrade: A direct, high-value alternative to Japanese, German, and other premium imported diaphragm valves, reducing both capital and maintenance expenses.
If diaphragm valve maintenance is a pain point in your operation, it's time for a smarter design. Let's discuss how HANDA's solution can enhance your electrolyzer's reliability.
