As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance, reliable fluid control solutions for demanding global markets. Our Marine Gate Valve, custom-built with a 304 Stainless Steel body and rated for 2000 WOG with threaded ends conforming to MSS SP-80, represents our commitment to precision engineering and durability. This valve is engineered to deliver exceptional shut-off capability and long service life in harsh marine and industrial environments, offering our clients a robust component that stands up to corrosion, high pressure, and frequent operation.
We understand that off-the-shelf solutions often fall short in specialized applications. That's why we focus on non-standard customization, tailoring dimensions and specifications to fit your unique system requirements perfectly. With an annual export value ranging between US$1 Million and US$1.5 Million, our products have gained trust across diverse regions including North America, Southeast Asia, Europe, and Africa, proving their reliability in varied operational conditions.
Core Features & Technical Advantages:
- Superior Corrosion Resistance: The 304 Stainless Steel construction provides excellent resistance to rust, pitting, and corrosion from seawater, chemicals, and atmospheric exposure, ensuring longevity and minimal maintenance.
- High-Pressure Integrity: Rated for 2000 WOG (Water, Oil, Gas), this valve guarantees a secure seal and reliable performance under high working pressures, preventing leaks and system failures.
- Precision Threaded Ends: The threaded connections are manufactured to MSS SP-80 standards, ensuring easy, leak-free installation and compatibility with standard piping systems, reducing assembly time and costs.
- Robust Gate Design: Features a rising stem and bolted bonnet design for straightforward operation, visual indication of valve position, and easy maintenance or repacking when required.
- Customizable Configurations: We offer non-standard customization on dimensions, stem material, packing type, and handwheel design to meet specific project layouts, space constraints, or operational protocols.
- Versatile Application: While ideal for marine applications (ballast systems, tank venting, fuel lines), this valve is equally suitable for industrial processes involving water, oil, gas, and mild chemical services.

Frequently Asked Questions (FAQ):
-
Q: What does "2000 WOG" rating mean for this valve?
A: "2000 WOG" indicates the valve's pressure rating for Water, Oil, and Gas service at ambient temperatures. It means the valve is designed to safely handle a working pressure of 2000 PSI for these media. -
Q: How does the "Non-Standard Custom" service work?
A: Our non-standard customization allows you to modify key dimensions like face-to-face length, port size, or stem length to fit your specific piping layout. You provide the required drawings or specifications, and we engineer and manufacture the valve accordingly. -
Q: Is 304 Stainless Steel suitable for full seawater immersion?
A: AISI 304 Stainless Steel offers good general corrosion resistance. For prolonged, full immersion in seawater, 316 SS is often recommended for higher molybdenum content. We can advise on material selection based on your specific fluid and environment. -
Q: What thread standards are available for the MSS SP-80 ends?
A: Typically, we provide NPT (National Pipe Taper) threads as standard, which is common in MSS SP-80. BSPT (British Standard Pipe Taper) threads are also available upon request. Please specify your requirement. -
Q: Can this valve be used for throttling flow control?
A: Gate valves are primarily designed for isolation (fully open or fully closed). Using them for throttling can cause vibration, wire-drawing on the seat, and premature wear. We recommend using globe or control valves for precise flow regulation. -
Q: What is the lead time for a custom, non-standard order?
A: Lead time depends on the complexity of customization and current production schedule. Generally, it may range from 4 to 8 weeks after finalizing specifications. We provide a confirmed timeline upon order review. -
Q: Do you provide pressure test certificates with the valves?
A: Yes, as an ISO9001 certified manufacturer, we perform and document standard hydrostatic shell and seat tests. Test certificates can be provided with the shipment upon request. -
Q: What are the main applications for this marine gate valve beyond ships?
A> Besides marine uses (ballast, bilge, fuel), it is widely used in coastal power plants, desalination facilities, chemical processing plants, offshore platforms, and any industrial system requiring corrosion-resistant, high-pressure shut-off valves.
