As a leading manufacturer with a strong foothold in the global valve market, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves tailored for demanding applications. Our DIN 3352 Standard Marine Gate Valve exemplifies our commitment to precision engineering and reliability. Designed specifically for the rigorous conditions of marine environments, this valve ensures secure fluid isolation and control on ships, offshore platforms, and port facilities. With an annual export value of US$1-1.5 million and a presence across continents from North America to Southeast Asia, we understand the critical need for durable, compliant components that shipbuilders and marine engineers can trust implicitly.
This marine gate valve is not just a component; it's a safeguard for your vessel's piping systems. Manufactured in strict accordance with the DIN 3352 standard, it guarantees dimensional interchangeability, mechanical strength, and performance consistency expected in professional marine engineering. Each valve is backed by a comprehensive Mill Test Report (MTR), providing full traceability of materials and verification of mechanical properties, giving you complete confidence in its quality and suitability for your project.
Core Features & Technical Advantages:
- Robust Construction for Harsh Environments: The valve body and internal components are crafted from materials selected for exceptional corrosion resistance and mechanical strength, such as cast steel (WCB), stainless steel (CF8/CF8M), bronze, and duplex steel. This ensures long-term, maintenance-free operation even when exposed to seawater, high humidity, and variable temperatures.
- Superior Sealing Performance: Features a flexible wedge or solid wedge design paired with precision-machined seats. This configuration provides a bubble-tight shut-off, minimizing leakage risks and ensuring system integrity under high-pressure conditions common in marine fuel, ballast, and cooling water lines.
- Easy Operation and Maintenance: The design prioritizes user-friendliness. A rising stem provides clear visual indication of the valve position (open/closed). The handwheel operation is smooth, and options for gear operators or electric actuators are available for remote or automated control in hard-to-reach areas onboard.
- Versatile Flange Connections: Equipped with flanged ends conforming to DIN standards, ensuring easy and leak-proof integration into existing shipboard piping systems. This simplifies installation and replacement procedures.
- Full OEM Compatibility: We offer comprehensive OEM services. Valves can be customized in terms of material grade, pressure rating (PN10, PN16, PN25, PN40), size (DN50 to DN600), and actuation method to meet your specific design drawings and technical specifications.

Frequently Asked Questions (FAQ)
-
Q: What is the significance of the DIN 3352 standard for this marine gate valve?
A: DIN 3352 is a German industrial standard that specifies requirements for gate valves, including dimensions, pressure ratings, materials, and testing. Valves conforming to this standard ensure interchangeability, reliable performance, and are widely accepted in international marine and industrial projects, particularly in European and global markets. -
Q: Is the Mill Test Report (MTR) provided with every valve?
A: Yes, a comprehensive Mill Test Report is provided as standard with each valve. This document details the chemical composition and mechanical properties of the materials used (like the valve body and stem), providing traceability and proof of compliance with specified material grades. -
Q: What materials are most suitable for seawater applications?
A: For optimal corrosion resistance in seawater, we recommend materials like Austenitic Stainless Steel (CF8/CF8M/AISI 316) or Duplex Stainless Steel. Bronze (C95800) is also a traditional and effective choice for many marine services. The best material depends on the specific fluid, temperature, and pressure. -
Q: Can these valves be customized for specific OEM requirements?
A: Absolutely. As a manufacturer, we specialize in OEM services. We can customize the valve's dimensions, pressure rating, material specification, face-to-face length, flange standards, and actuation method (manual, gear, electric) to match your technical drawings and exact specifications. -
Q: What pressure classes (PN) are available?
A: Our DIN 3352 marine gate valves are typically available in standard pressure classes including PN10, PN16, PN25, and PN40. Other pressure ratings can be developed based on customer demand and project requirements. -
Q: Do you offer actuation options beyond manual handwheel operation?
A: Yes. While handwheel operation is standard, we can equip the valves with bevel gear operators for high-torque applications or electric actuators for remote and automated control systems, which are common in modern vessel designs. -
Q: What testing is performed on the valves before shipment?
A: Each valve undergoes rigorous pressure testing, including a shell test (body strength) and a seat leak test, performed in accordance with standards like API 598 or DIN 3230. These tests verify the valve's integrity and sealing capability under pressure. -
Q: What are your main shipping ports and lead times?
A> We ship from major Chinese ports including Shanghai, Guangzhou, Hong Kong, and Beijing, offering flexible logistics. Lead times vary based on order quantity, customization level, and material availability. Standard configurations typically have shorter lead times.
