As a specialized manufacturer with a focus on marine fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Non-Standard Marine Gate Valve. Engineered for demanding offshore and shipboard applications, this valve is designed to provide reliable isolation in pipelines where standard sizes fall short. Our commitment since 2016 has been to deliver robust, specification-compliant valves that withstand the harsh marine environment. This particular model, featuring stainless steel trim and a 300LB pressure rating, is built to offer exceptional durability and leak-tight shutoff, ensuring the safety and efficiency of your critical marine systems.
The core value of this valve lies in its adaptability and compliance. We understand that marine projects often require custom solutions, which is why we offer non-standard sizing while adhering strictly to the BS 3464 standard for design and manufacturing. This approach provides you with the flexibility needed for unique installations without compromising on the recognized quality and safety benchmarks required in the industry.
Key Features & Technical Advantages:
- Superior Corrosion Resistance: The stainless steel trim (standard 304/316) is specifically selected to combat the corrosive effects of seawater, bilge water, and marine atmospheres, significantly extending the valve's service life and reducing maintenance cycles.
- Robust Construction for High Pressure: With a 300 LB (PN 50) pressure rating and a bolted bonnet design, the valve ensures a secure, pressure-boundary seal. The rising stem design provides a clear visual indication of the valve position (open or closed), enhancing operational safety.
- Customizable Non-Standard Design: We specialize in manufacturing valves outside typical size ranges. Whether you need an unusual flange dimension, face-to-face length, or port size, our engineering team can tailor the valve to fit your specific piping layout and space constraints.
- BS 3464 Compliance: Manufactured in accordance with British Standard 3464 for iron gate valves, this valve meets rigorous specifications for materials, dimensions, pressure-temperature ratings, and testing. This provides assurance of quality and interoperability in international marine projects.
- Versatile Actuation Options: While supplied with a standard handwheel for manual operation, the valve is designed to be easily fitted with gear operators or pneumatic/electric actuators for remote or automated control systems, offering flexibility for various levels of automation onboard.
The technical specifications below outline the standard configuration. Please note that as a non-standard valve, many parameters can be adjusted upon request.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "non-standard" mean for this valve?
A: "Non-standard" primarily refers to dimensions outside common, catalogued size ranges. This includes unusual bore sizes, flange dimensions (face-to-face, bolt circle), or overall lengths. We customize the valve geometry to match your specific piping drawings or space limitations while maintaining pressure integrity and standard compliance. -
Q: Is the BS 3464 standard suitable for use outside the UK or Europe?
A: Absolutely. BS (British Standard) 3464 is a well-respected and widely recognized specification in the global marine and offshore industries. Many shipowners, shipyards, and engineering firms worldwide specify BS standards for gate valves due to their rigorous requirements for design, materials, and testing. -
Q: Can you provide valves with different end connections besides flanged?
A: Yes. While flanged ends are standard for this class, we can manufacture the valve with butt-weld ends, socket-weld ends, or other connection types as required by your piping specification. This is part of our non-standard customization service. -
Q: What is the lead time for a custom non-standard valve?
A: Lead time varies depending on the complexity of the customization, material availability, and current production schedule. Generally, it is longer than for standard valves. We provide a specific project timeline upon receipt of your detailed requirements and technical drawings. -
Q: Does the stainless steel trim make the valve suitable for seawater service?
A: The standard 304/316 stainless steel trim offers good general corrosion resistance. For full, continuous seawater service, we often recommend upgrading to a higher-grade stainless steel like 316L or super duplex, or considering alternative trim materials, which we can provide upon request. -
Q: Are test reports provided with the valve?
A> Yes. As part of our ISO9001 quality procedures and BS 3464 compliance, each valve undergoes hydrostatic shell testing and, typically, a seat leak test. A certified test report detailing these results can be provided with the shipment. -
Q: Can this valve be automated?
A: The design is compatible with automation. The rising stem, bolted bonnet configuration is suitable for mounting various pneumatic, electric, or hydraulic actuators. We can supply the valve as a manual unit ready for later actuation or deliver it as a complete automated package. -
Q: What are the main applications on a ship for this valve?
A> Typical applications include isolation service on seawater cooling lines, ballast systems, firefighting lines, fuel oil transfer lines (where permitted by class), bilge systems, and general service lines in engine rooms and pump rooms where reliable shut-off is required.
