Key Features and Technical Specifications
- Customized Design: Non-standard dimensions, end connections, and pressure ratings available to fit unique pipeline layouts and system requirements. Our engineering team works closely with clients to develop tailor-made solutions.
- Superior Corrosion Resistance: Specialized anti-corrosion coatings (epoxy, PTFE, zinc-rich paint) applied to both internal and external surfaces. Materials such as Duplex Stainless Steel, Super Duplex, or Hastelloy are available for extreme saline and H₂S environments.
- Robust Construction: Designed per API 6D, BS 1868, or ISO 17292 standards. The check valve features a swing-type or lift-type disc mechanism to prevent backflow effectively, even under high-pressure differentials.
- Wide Temperature Range: Suitable for operating temperatures from -46°C to +250°C, with optional cryogenic or high-temperature variants.
- Low Pressure Drop: Optimized internal flow path ensures minimal resistance, reducing energy loss in fluid systems.
- Easy Maintenance: Modular design allows for quick disassembly and replacement of internal parts without removing the valve body from the pipeline.

Application Advantages for Offshore Platforms
- Reliable Backflow Prevention: Prevents reverse flow in ballast water systems, fire-fighting lines, seawater cooling, and crude oil transfer systems. The check valve operates automatically, requiring no external power.
- Marine-Grade Protection: Coating and material selection comply with NORSOK M-501 or ISO 20340 (upon request) to withstand salt spray, UV radiation, and chemical exposure.
- Space-Saving Design: Compact dimensions allow installation in confined spaces typical of offshore modules and skids.
- Certified Quality: Valves are manufactured under ISO9001:2015 quality management system. Each unit is hydrostatically and pneumatically tested before shipment.

Frequently Asked Questions (FAQ)
-
Q: Can you provide fully customized non-standard dimensions?
A: Yes, we specialize in non-standard designs. Our engineers can modify length, flange drilling, face-to-face dimensions, and disc profile according to your pipeline layout. -
Q: What corrosion-resistant coatings are available?
A: We offer epoxy (high-build), PTFE, zinc-rich primer, and even thermal spray coatings. The coating system can be selected based on your service environment and required salt spray resistance (e.g., 500–2000 hours). -
Q: What is the typical lead time for custom valves?
A: Lead time depends on complexity and quantity. Generally, it ranges from 4 to 12 weeks. Rush orders can be accommodated with prior arrangement. -
Q: Do you provide third-party inspection certificates?
A: Yes, we can arrange inspection by DNV, Lloyds, ABS, BV, or other third parties. Material certificates and test reports are included. -
Q: Can these check valves be used for subsea applications?
A: Our valves are designed for topside and subsea use. For subsea, we offer additional options like hydraulic dampeners or ROV-friendly features. Please consult our team for specific depth ratings. -
Q: What is the maximum working pressure for your check valves?
A: Standard design goes up to Class 2500 (approx. 420 bar). Higher pressure ratings (e.g., 10,000 psi) can be engineered upon request. -
Q: How do you ensure coating quality?
A: Coating thickness is measured with a dry film gauge. Adhesion tests (cross-cut or pull-off) and holiday detection are performed as per customer specifications. -
Q: What is your after-sales support policy?
A: We provide a 12-month warranty against manufacturing defects. Technical support is available via email or video call for installation and troubleshooting.
