Providing Customized Valve Solutions

Professional Customized Large-Diameter Valve Solutions for EPC & Industrial Projects

In industrial sectors where efficiency, safety, and compliance are non-negotiable—especially for EPC (Engineering, Procurement, Construction) projects—valves are the backbone of fluid control systems. As a China-based professional industrial valve manufacturer with decades of expertise, Tianyu Valves specializes in customizing large-diameter ball valves and butterfly valves (DN300 to DN4000) tailored to your unique operating conditions. Whether you’re managing an oil & gas pipeline EPC project, a power plant upgrade, or a municipal wastewater treatment facility, we deliver solutions that align with international standards, project timelines, and long-term reliability needs.
 
Unlike one-size-fits-all valves, our customized products are engineered to solve your specific challenges—from extreme temperatures and high pressures to corrosive media or space-constrained installations. We don’t just supply valves; we partner with EPC contractors, plant operators, and industrial buyers to provide end-to-end support, ensuring seamless integration into your systems.

Our Custom Valve Range: Focus on Large-Diameter Ball & Butterfly Valves

At Tianyu, we prioritize the products that matter most to industrial and EPC projects: large-diameter ball valves and large-diameter butterfly valves. Our customization capabilities extend to every critical component, ensuring compatibility with your process and compliance with global standards (API, ISO, CE, etc.).

Core Advantages of Tianyu’s Customized Valves for EPC & Industrial Buyers

Our customization services are designed to address the unique pain points of EPC contractors and industrial operators—from tight project schedules to strict regulatory requirements. Here’s what sets us apart:

1. Tailored to Your Exact Operating Conditions

Every custom valve starts with a deep dive into your needs:
  • Media Compatibility: Choose materials (e.g., Hastelloy for acidic media, duplex SS for seawater) to resist corrosion and wear.
  • Extreme Environment Adaptation: Engineer valves for high temperatures (up to 450℃ for power plants) or cryogenic conditions (-196℃ for LNG EPC projects).
  • EPC Space & Installation Needs: Customize connection types (welded, flanged, lugged) or actuator mounting to fit tight project layouts.

2. EPC-Ready Compliance & Certifications

EPC projects demand strict adherence to international standards—and we deliver:
  • Key Certifications: API 6D (ball valves), API 609 (butterfly valves), ISO 9001/14001/18001, CE (0036), SIL3, API 607/6FA (fire-safe), and ISO 15848-1 (emission control).
  • Third-Party Testing: Every large-diameter valve undergoes rigorous testing (pressure, leakage, endurance) with detailed reports—critical for EPC project 验收 (acceptance).

3. Flexibility for All Project Sizes

  • Minimum Order Quantity (MOQ): 1 piece—ideal for EPC prototype testing or small-batch replacements.
  • Bulk Production Support: Scale up to hundreds of units for large-scale EPC projects, with consistent quality and on-time delivery (typical lead time: 4–8 weeks for custom large-diameter valves).

4. Cost-Effectiveness for Long-Term Operations

Custom valves from Tianyu reduce total cost of ownership (TCO) for EPC and industrial clients:
  • Durability: Materials and designs are optimized for your media, reducing maintenance frequency and downtime.
  • Energy Efficiency: Full-port ball valves and low-torque butterfly valves minimize pressure loss, cutting operational costs.
  • One-Stop Service: Avoid delays from multiple suppliers—we handle design, manufacturing, testing, installation guidance, and after-sales support.

Customization Process: Streamlined for EPC Project Timelines

We understand EPC projects run on tight schedules. Our 5-step customization process ensures speed, transparency, and alignment with your milestones:
  1. Needs Analysis & Technical Consultation
    Our engineering team (fluent in English, Spanish, and Arabic) collaborates with your EPC technical team to confirm:
    • Fluid media (oil, gas, steam, wastewater), pressure (PN10–PN40), and temperature ranges.
    • Large-diameter specs (DN size, end connections, actuator type).
    • Compliance requirements (e.g., API 6D for oil,steam, air projects, NSF 61 for drinking water).
  2. Solution Proposal & Quotation
    Within 48 hours, we deliver a detailed proposal including:
    • 2D/3D CAD drawings of the custom valve.
    • Material certificates, certification plans, and lead time.
    • Transparent pricing (no hidden costs for EPC bulk orders).
  3. Prototype & Pre-Production Testing
    For critical EPC projects, we produce a prototype for your inspection. Testing includes:
    • Hydrostatic/pneumatic pressure tests (per API standards).
    • Fire-safe testing (API 607) and leakage testing (ANSI Class VI for butterfly valves).
    • Third-party witness testing (upon request, e.g., TUV or SGS).
  4. Mass Production & Quality Control
    Once approved, we start production with real-time progress updates for your EPC team. Every valve undergoes:
    • In-line inspections (material composition, dimensional accuracy).
    • Final performance testing (actuator operation, seal integrity).
  5. Delivery, Installation Support & Acceptance
    • We ship via reliable logistics (sea/air freight) with all required documents (certificates, test reports, installation manuals).
    • Our technicians provide on-site or remote installation guidance for EPC teams.
    • Formal acceptance sign-off to ensure compliance with your project standards.

Industry-Specific Custom Solutions for EPC Projects

Tianyu’s customized large-diameter valves are engineered for the world’s most demanding industrial sectors—with a track record of supporting EPC projects globally:

1. Oil & Gas Industry

  • Custom Valves: DN600–DN1200 full-welded trunnion ball valves (API 6D, Class 600) for buried pipelines.
  • Why It Works: Corrosion-resistant duplex stainless steel (2205) withstands harsh offshore/marine environments; fire-safe design meets EPC safety requirements.

2. Power Generation

  • Custom Valves: DN800–DN1600 triple offset butterfly valves (API 609) for steam and cooling water systems.
  • Why It Works: Metal hard seals handle high temperatures (up to 400℃); electric actuators integrate with power plant DCS systems.

3. Municipal Water & Wastewater

  • Custom Valves: DN1000–DN4000 rubber-lined butterfly valves (NSF 61) for wastewater treatment plants.
  • Why It Works: EPDM linings prevent contamination; large sizes reduce flow resistance for municipal EPC infrastructure projects.

4. Petrochemical & Chemical

  • Custom Valves: DN300–DN800 Hastelloy ball valves for acidic media (e.g., sulfuric acid).
  • Why It Works: High-alloy materials resist corrosion; DBB (Double Block & Bleed) design ensures zero leakage for hazardous chemicals.
