One solution, two layers of protection: HANDA Integrated Sea Chest Strainer with MGPS (Model KTFH-01)
Every ship operator knows the pain of marine organism attachment – blocked strainers, clogged coolers, reduced heat exchange efficiency, and the costly manual cleaning cycles that follow.
HANDA’s solution combines mechanical filtration with active electrochemical anti-fouling in a single, compact unit:
🔹 Mechanical barrier:​ 316L stainless steel precision filter basket captures seaweed, shells, gravel and other solid impurities – keeping downstream pipelines clean.
🔹 Active protection:​ Copper-aluminum alloy electrodes, energized by low-voltage DC (12V, 0.1–2A adjustable), continuously ionize seawater to release Cu²⁺ and Al³⁺ ions. These ions spread throughout the sea chest and piping, preventing barnacle, algae and shellfish adhesion while also slowing electrochemical corrosion of steel pipes.
🔹 Built for marine duty:​ Mud box IP68, control box IP44; CS/HDG body; seasonal current adjustment standard (summer 0.3A, winter 0.1A); fault alarm with remote signal output; designed per CB/T 497-2015 and IMO MEPC.1/Circ.622.
🔹 Low maintenance, long life:​ Simple monthly cleaning of filter basket and gentle electrode wipe-down; annual electrode thickness check; 24h continuous or intermittent operation with power consumption as low as 5–80W.
Whether you’re retrofitting an existing vessel or specifying for newbuild, this integrated unit saves space, reduces piping complexity, and delivers reliable, year-round protection.

One valve, smarter routing: HANDA 3‑Way / 4‑Way Ball Valves for process changeover & manifolding
Process lines don’t always need more valves — they need the rightmultiport logic.
HANDA’s L-port (directional diverter)​ and T-port (mixing/diverting)​ ball valves are built to consolidate routing: fewer flanges, fewer potential leak points, and a cleaner P&ID ex*****on — whether you’re switching tanks, backwashing filters, or managing bypass/recirculation loops.
Why engineers spec us in
Full-bore flow path​ → lower local losses when aligned
Flexible ports​ → solve “tank A/B/C select,” filter bank changeover, blend/bypass in one body
Project-grade paperwork​ → material certs, NDE/leak test records, and traceability aligned to TSG/GB discipline
Mounting discipline​ → ISO pad + gearbox or actuator kits for safer, repeatable operation
Used across chemical utility skids, WWTP filter galleries, tank farms, HVAC/heat networks, and O&G pigging manifolds.

Custom Engineered for Purity & Performance: HANDA’s Graphite-Free RPTFE Seat Butterfly Valve
We’ve received increasing requests for valves that eliminate the risk of carbon contamination from traditional graphite-containing seats. In response, HANDA introduces our custom DBA8150-G series​ – a high-performance wafer double eccentric butterfly valve featuring a white RPTFE seat reinforced solely with glass fiber (zero graphite).
Why Graphite-Free Matters:
In industries such as pharmaceuticals, fine chemicals, electronics, and food processing, even trace amounts of graphite can contaminate the product or process. Our seat formulation eliminates that risk while maintaining excellent sealing and wear characteristics.
Engineered for Reliability:
Seat Hardness:​ Glass fiber reinforcement ensures the seat resists deformation and maintains tight shut-off over thousands of cycles.
Material Compatibility:​ 304 stainless steel body and disc, paired with a 17-4PH stem, offer robust corrosion resistance in aqueous and mild chemical services.
Flexible Mounting:​ The worm gear operator can be oriented in any direction, accommodating tight spaces and various pipeline configurations.
This valve is a perfect fit for:
Deionized water / purified water systems
Clean-in-place (CIP) circuits
Low-corrosion chemical lines
HVAC and cooling water isolation
Delivered as a complete, ready-to-install assembly with gearbox and mounting kit.

Process Reliability Starts with the Right Valve: HANDA Control Valve Series for Chlor-Alkali & High-Pressure Steam
In chemical processing, valve failure isn’t just a maintenance issue—it’s a safety and production risk. When your media includes chlorine gas, hot caustic, or high-pressure steam, off-the-shelf solutions fall short.
That’s why HANDA’s Control Valve Series is engineered around your specific process conditions. Here’s what sets our solution apart:
✔ Material Expertise
We specify 321 stainless steel for chloride-laden streams (brine, caustic) and select 16Mn, Q345E, or WCB depending on temperature and pressure profiles. Every material choice is traceable and documented.
✔ Precision Control & Tight Shut-Off
Our pneumatically actuated control valves (ZJHM series) achieve Class VI metal-to-metal sealing per GB/T 4213—essential for containing toxic gases like chlorine. For steam applications up to PN63, we ensure stable modulation and reliable isolation.
✔ Integrated Smart Package
Each valve comes with:
Siemens SIPART PS2 positioner (intrinsically safe, with/without feedback)
ASCO solenoid valve
Mechanical limit switch box
SMC filter-regulator
Complete bolting and gaskets
All components are assembled, calibrated, and tested before shipment, saving you engineering hours and procurement coordination.
✔ EAEU Compliance Ready
Fl**ges per GOST 33259-2015, declarations under TR CU 010/032/020—our documentation package supports your certification and customs clearance in Russia and CIS markets.
Delivered for a Recent Chlor-Alkali Project:
10+ valve stations covering chlorine isolation, brine circulation, caustic handling, and steam reduction
Full pneumatic actuation with spring-return fail-safe configurations
Intrinsic safety (Ex ia) for hazardous zones
When your process is critical, choose a valve partner who understands the chemistry.

Engineered for Serviceability: Rethinking Seat Retention in Butterfly Valves
A common frustration during valve maintenance is the seized or corroded locking screw that holds a seat insert in place. What if you could eliminate that problem entirely?
At HANDA, our custom-engineered Double Offset Fl**ge Butterfly Valves​ now offer a screw-free seat insert design​ based on direct client feedback. The insert is precisely threaded into the valve body, forgoing the traditional fixing screw.
Why This Matters for Your Plant:
✔ Eliminates a Failure Point:​ No screw means no risk of corrosion, galling, or breakage during future disassembly.
✔ Ensures Concentricity:​ A threaded connection provides secure, even seating.
✔ Enables Predictable Maintenance:​ With a key procedural step​ – applying anti-seize lubricant on threads during installation – the stainless-steel components are protected from galling. This guarantees the seat can be removed smoothly when it’s time for replacement, slashing maintenance time and cost.
This design philosophy prioritizes Total Cost of Ownership, focusing not just on initial performance but on decades of reliable, serviceable operation. It’s a detail that makes a major difference during a turnaround.
Designing valves for the people who maintain them.
