As a professional valve manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Marine Gate Valve designed to DIN 3352 standards. Engineered for demanding maritime and industrial applications, this valve combines robust construction with a full port design to ensure minimal pressure drop and maximum flow efficiency. Our years of experience supplying to global markets, including North America, Europe, Southeast Asia, and beyond, have refined this product to meet the exacting requirements of shipbuilders, offshore platform operators, and industrial fluid handling systems.
Our Marine Gate Valve is built to deliver reliable shut-off and control in critical piping systems. The full port design, a key feature, means the valve's internal diameter matches the pipeline diameter, significantly reducing flow resistance and turbulence. This is crucial for systems where maintaining pressure and flow rate is essential, such as ballast systems, fuel lines, cooling water circuits, and cargo handling on vessels. We utilize high-grade materials and precision machining to ensure long service life even in corrosive marine environments.
Key Product Features & Technical Advantages:
- DIN 3352 Compliance: Manufactured to the internationally recognized DIN 3352 standard for wedge gate valves, ensuring dimensional interchangeability, reliable performance, and acceptance in global maritime projects.
- Superior Flow Efficiency: The full port (full bore) design offers an unobstructed flow path, minimizing pressure loss and allowing for pigging operations in pipelines.
- Robust Construction: Available in various body materials like cast steel (WCB), ductile iron, and stainless steel (CF8/CF8M) to suit different fluid media and corrosion resistance needs.
- Reliable Sealing: Features flexible wedge or solid wedge designs with hardened stainless steel or bronze seats for tight, bubble-tight shut-off, preventing leakage in both directions.
- Versatile Actuation: Standard operation is via a handwheel. Options for gear operators (for high torque) and electric/pneumatic actuators are available for remote or automated control systems.
- Easy Maintenance: Bolted bonnet design allows for straightforward disassembly and maintenance of internal components without removing the valve body from the pipeline.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of a full port design in a gate valve?
A: The primary advantage is minimized flow restriction. A full port valve has a bore diameter equal to the pipe's inner diameter, drastically reducing pressure drop and turbulence compared to a standard port valve. This is vital for applications requiring maximum flow capacity or where pipeline cleaning pigs need to pass through.
Q2: Can this valve be used with seawater or other corrosive media?
A: Yes, absolutely. We offer material options specifically for corrosive services. For seawater, we recommend bodies in Duplex stainless steel or super duplex, with appropriate trim materials like stainless steel 316 or bronze. Please specify your media and operating conditions for a precise material recommendation.
Q3: Is this valve suitable for on/off service only, or can it be used for throttling?
A: Gate valves are primarily designed for isolation (fully open or fully closed). Using them for throttling control can cause vibration, cavitation, and accelerated wear on the seat and disc surfaces. We recommend using control valves or globe valves for precise flow regulation.
Q4: Do you provide valves with different flange standards, like ANSI?
A: Yes. While the standard offering is DIN flanges (EN 1092-1), we can manufacture valves with ANSI B16.5 flanges (Class 150 or 300) upon request. This ensures compatibility with American-standard piping systems.
Q5: What types of actuators can be fitted to this valve?
A: This valve can be fitted with multi-turn electric actuators, pneumatic actuators (scotch-yoke or rack & pinion), or manual gearboxes. We can source and assemble the actuator package as a complete unit, ready for installation.
Q6: What is the typical lead time for an OEM order?
A: Lead time depends on order quantity, material selection, and any customizations. For standard materials and sizes, typical production time is 4-6 weeks. We provide a firm schedule upon order confirmation.
Q7: How do you ensure quality control?
A> Our production follows the ISO9001 quality management system. Key processes include material certification checks, dimensional inspection, pressure testing (shell and seat tests per API 598 or equivalent standards), and final performance verification before packing.
Q8: Can you provide documentation like test reports and material certificates?
A: Yes, we provide full documentation packages, including Material Test Certificates (MTC/CMTR), pressure test reports, and certificates of conformity. These are essential for marine classification society approvals and project documentation.
