As a leading valve manufacturer based in Shanghai, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable flow control solutions for the demanding marine and oil & gas industries. Our Gate Valve, engineered specifically for crude oil tanker piping systems, embodies our commitment to safety, durability, and performance. Designed in strict accordance with the DIN 3352 standard and featuring a critical fire-safe option, this valve is built to ensure secure and efficient operation in the most challenging offshore and onshore environments. With over eight years of manufacturing expertise since our establishment in 2016, we understand the precise requirements for tanker applications and deliver products that meet rigorous international expectations for quality and reliability.
This gate valve is engineered to control the flow of crude oil, fuel, and other hydrocarbons within tanker piping systems. Its robust construction and specialized design make it suitable for main line isolation, manifold systems, and loading/unloading arms. The primary advantage lies in its combination of a standard bubble-tight shut-off with an integrated fire-safe design, which provides an additional layer of safety in emergency situations. For our clients across North America, South America, Europe, Asia, and Africa, this translates into enhanced operational safety, reduced downtime, and long-term cost savings through superior durability.
Key Features & Technical Advantages:
- Fire-Safe Design: In the event of a fire, the valve's metal-to-metal secondary seal activates to maintain a seal, preventing catastrophic fluid release and conforming to common fire-safe testing standards like API 607/API 6FA.
- DIN 3352 Compliance: Manufactured to the DIN 3352 standard for wedge gate valves, ensuring dimensional interchangeability, reliable performance, and acceptance in European and international markets.
- Rugged Construction: The valve body, bonnet, and wedge are typically constructed from high-grade carbon steel (WCB) or ductile iron, offering excellent resistance to pressure, mechanical stress, and corrosive elements found in crude oil.
- Bidirectional Sealing: Provides effective sealing against pressure from either direction of flow, which is crucial for tanker applications where flow direction may change.
- Low Operating Torque: The parallel or wedge gate design ensures relatively low operating torque, making manual operation smoother and reducing wear on gear operators.
- Full Bore Design: When fully open, the valve provides a straight-through flow path with minimal pressure drop, maximizing pumping efficiency during tanker loading and unloading operations.
- Versatile Actuation: Available with a standard handwheel for manual operation or can be fitted with gearboxes for larger sizes/higher pressures, or even automated with electric or pneumatic actuators upon request.
- Extended Service Life: Hard-faced seats and stems (options like Stellite) are available for applications with abrasive media, significantly extending maintenance intervals.

Frequently Asked Questions (FAQ)
1. What does "Fire-Safe Option" mean for this gate valve?
The fire-safe option means the valve is designed to maintain a seal (contain the fluid) even when exposed to high temperatures from an external fire. It typically involves a secondary metal-to-metal sealing mechanism that engages if the primary soft seals (like graphite packing) are compromised by heat. This is a critical safety feature for hydrocarbon services on tankers.
2. Is this valve suitable for other fluids besides crude oil?
Yes. While designed for crude oil tanker piping, this DIN 3352 gate valve is suitable for a wide range of other fluids including fuel oil, diesel, lubricating oil, and other non-aggressive liquids in industrial and marine applications. Material selection can be adjusted based on fluid compatibility.
3. Can you provide valves with different flange standards, like ANSI/ASME?
Absolutely. While DIN flanges are standard, we can manufacture valves with ASME B16.5 flanges (Class 150, 300, 600) to suit specific project requirements in markets like North America. Please specify your needed pressure class and flange facing during inquiry.
4. What is the typical delivery lead time for an order?
Lead time depends on the order quantity, size, and material specifications. For standard configurations in carbon steel, typical lead times range from 4 to 8 weeks. We provide a confirmed schedule upon receipt of a formal order.
5. Do you offer actuated versions of this valve?
Yes. We can supply the valve prepared for actuation (with a mounting pad) and can source and fit electric, pneumatic, or hydraulic actuators as a complete package. This is a customizable option available upon request.
6. How does the DIN 3352 standard benefit me as a buyer?
The DIN 3352 standard ensures dimensional consistency, performance reliability, and interchangeability with other valves built to the same standard. This simplifies procurement, installation, and potential replacement, especially for projects following European or international specifications.
7. What documentation is provided with the valves?
Standard documentation includes a Material Test Certificate (MTC) for body/bonnet materials, a pressure test certificate, a detailed packing list, and operational manuals. Additional certification, such as a fire test certificate for the fire-safe option, can be provided upon request.
8. What is your payment terms and packaging for export?
Standard payment terms are T/T (30% deposit, 70% against copy of B/L). Valves are exported in robust wooden cases or crates with internal waterproofing to ensure they arrive in perfect condition, suitable for long-distance sea freight.
