Valves that hold
when the media won't.
Zero-leakage lined valve packages and factory-backed actuation solutions. Built to withstand your harshest acids, chlorine, and slurries — at half the lead time and cost of Western OEMs.
Not just a bare valve trader. A factory-backed solutions partner.
Holding factory manufacturing equity gives VALCO total command over casting integrity, fluoroplastic lining thickness, and pressure testing rigor.
While conventional trading companies broker standard catalog parts, our dedicated engineering team sizes pneumatic and electric actuation packages, reviews complex P&ID project data sheets, and provides full technical drawings before fabrication.
- Core Manufacturing: Fluoroplastic lined valve bodies (ball, butterfly, gate, globe, check, safety) cast, lined, and tested within our holding foundry.
- Actuation Engineering: Pneumatic, electric, and smart positioner packages matched precisely to operating torque and media temperatures.
- Document Package: Complete BOM, General Arrangement (GA) drawings, MTRs (EN 10204 3.1), and inspection test plans for EPC submittals.
Engineered for zero-leakage in aggressive chemical services.
Handling strong acids, wet chlorine, caustic slurries, and organic solvents requires uncompromised polymer adhesion and precise dimensional stability.
Precision PTFE / PFA Lining Technology
We employ high-density Virgin PTFE, PFA, and FEP resins sourced from tier-one polymer suppliers. Cast valve bodies feature dovetail anchoring grooves and locking holes to prevent lining collapse or liner migration under full vacuum and thermal cycling.
- Dovetail Anchor Grooves: Locks fluoroplastic securely to carbon steel and stainless steel bodies.
- Full Vacuum Resistance: Verified liner adhesion across full operational temperature ranges (-29°C to +180°C).
- 100% Spark Testing: Non-destructive high-voltage spark testing (20kV) ensures pinhole-free integrity before assembly.
Hydrostatic Shell Test
Shell pressure testing at 1.5× nominal working pressure to ensure pressure boundary integrity.
Seat & Seal Tightness
Low-pressure pneumatic & hydro seat tests achieving Class VI / Rate A bubble-tight shutoff.
High-Voltage Spark Test
20 kV dielectric spark test on all internal lined surfaces to guarantee zero micro-porosity.
Witness FAT & NDT
Full support for client and third-party witness testing (SGS, TÜV), PMI, radiography, and hardness checks.
Direct dimensional replacement for Western legacy brands.
End users and EPCs operating plants with 15–20 year old equipment frequently encounter discontinued models, 30+ week lead times, or prohibitive OEM replacement costs from brands such as Emerson/Fisher, KITZ, and Tyco.
VALCO provides exact dimensional, flange standard (DIN EN / ASME / JIS), and face-to-face drop-in equivalents based solely on your existing valve tag, nameplate, or line data sheet.
| Engineering Factor | Western Legacy OEM | VALCO Equivalent |
|---|---|---|
| Lead Time | 24 – 36 Weeks | 6 – 10 Weeks |
| Project Cost | High OEM Markup | 1/2 – 2/3 OEM Cost |
| Face-to-Face Match | Proprietary / Standard | 100% Drop-in Equivalent |
| Certifications | ISO / CE / API | ISO / CE / API / ATEX |
Dedicated engineering desk supporting your technical bids.
Every inquiry is paired with experienced valve specialists and application engineers to ensure error-free specification before purchase orders are signed.
Data Sheet & BOM Review
Our engineers audit process operating conditions (media concentration, operating pressure, temperature range, particulate content) to select the correct polymer grade and trim construction.
GA Drawings & 3D Models
Fast-turnaround submittal packages including 2D General Arrangement drawings with dimensional tolerances and 3D STEP models for piping clash checks.
AVL & Vendor Qualification
We work directly alongside local regional agents and contractors to compile full qualification dossiers, audit documentation, and plant compliance reports for end-user AVL registration.
