Cryogenic Check Valve
Shanghai Zhibang Valve Manufacture Co., Ltd, with over 8 years of valve manufacturing expertise, proudly presents the Zhibang Marine Cryogenic Check Valve – a premium solution designed for extreme low-temperature applications. Engineered with a 316SS body and capable of operating at -196°C, this valve ensures reliable reverse flow prevention in marine, LNG, and cryogenic systems. Available in sizes DN15 to DN100 and pressure ratings PN1.6 to 4.0MPa, it offers flexibility for diverse piping requirements. Our flanged end design simplifies installation and maintenance, while the LR (Lloyd's Register) approval guarantees compliance with international marine standards. Trust Zhibang for durable, high-performance valves that protect your critical processes.
Key Features & Technical Specifications
- Extreme Low-Temperature Capability: Designed for working temperatures as low as -196°C, ideal for cryogenic fluids like LNG, liquid nitrogen, and oxygen. The valve's material and sealing technology ensure no brittle failure even under severe cold.
- High-Quality 316SS Body: The 316 stainless steel construction provides excellent corrosion resistance, especially in marine environments and cryogenic service. It resists pitting, crevice corrosion, and stress cracking.
- Broad Size and Pressure Range: Available in nominal diameters from DN15 to DN100, and pressure ratings from PN1.6 to 4.0MPa, covering a wide range of low-to-medium pressure systems.
- Flanged End Connection: Standard flanged ends (EN or ASME compatible) ensure easy installation and leak-tight joints. Custom flange standards available upon request.
- LR Approved Design: The valve carries Lloyd's Register (LR) type approval, confirming its suitability for marine and offshore applications. This certification ensures compliance with stringent international safety and quality norms.
- Non-Slam Operation: The check valve features a spring-assisted disc or swing-type mechanism that minimizes water hammer and ensures quiet, reliable closure.
- Low Pressure Drop: Optimized flow path reduces resistance, saving energy in pumped systems. The valve's internal geometry is designed for minimal turbulence.
- Customizable Options: Available with different disc materials (e.g., PTFE, PEEK), spring materials, and optional bonnet extensions for insulated piping.

Advantages for Your Applications
- Marine & Offshore Reliability: LR approval ensures the valve meets the rigorous demands of shipbuilding, LNG carriers, FSRUs, and offshore platforms. It passes shock, vibration, and fire tests.
- Long Service Life: The 316SS body and high-quality internals resist thermal cycling and cryogenic embrittlement, providing years of trouble-free operation.
- Cost-Effective Solution: By preventing backflow and protecting pumps/compressors, this valve reduces downtime and maintenance costs. Its low pressure drop also saves energy.
- Easy Maintenance: The flanged design allows quick removal without cutting pipes. Replaceable seats and discs extend overall valve life.
- Global Compliance: Designed in accordance with ISO, EN, and ASME standards. Can be supplied with material certificates, NDT reports, and factory test certificates.

Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for other cryogenic media besides LNG?
A: Yes, it is suitable for liquid nitrogen, liquid oxygen, liquid argon, liquid ethylene, and other cryogenic fluids within the temperature range. Material compatibility should be confirmed for specific media. -
Q: What is the maximum operating pressure for DN100 size?
A: For DN100, the valve is rated up to PN4.0 MPa (approximately 580 psi). Higher pressure ratings are available upon request; please specify your requirements. -
Q: Does the LR approval cover all sizes?
A: Yes, the LR type approval covers the full range DN15-DN100 and all pressure ratings. A copy of the certificate can be provided upon request. -
Q: Can you supply the valve with a position indicator or limit switch?
A: Optional accessories like a magnetic or mechanical indicator, limit switch box, or proximity sensors can be fitted for remote monitoring. These are available at extra cost. -
Q: What is the standard lead time?
A: Standard sizes (DN15-DN50) typically ship within 2–4 weeks. Larger sizes (DN65-DN100) may require 4–6 weeks. Custom orders are subject to confirmation. -
Q: Is the valve suitable for vertical installation?
A: The standard swing-type check valve can be installed in horizontal or vertical upward flow orientation. For vertical downward flow, a spring-loaded type is recommended – we can customize accordingly. -
Q: Do you provide material certificates and test reports?
A: Yes, we offer EN 10204 3.1 material certificates, NDT reports (X-ray, PMI), and hydrostatic/pneumatic test certificates as required. These can be included with the shipment. -
Q: What payment terms do you accept?
A: We commonly accept T/T, L/C, and Western Union for international orders. Payment terms (e.g., 30% deposit, 70% before shipment) are negotiable.
