Welcome to Shanghai Zhibang Valve Manufacture Co., Ltd., a professional valve manufacturer established in 2016. We specialize in providing robust and reliable flow control solutions for demanding industrial applications. Our Marine Oil Pipeline Gate Valve, designed in full compliance with the DIN 3352 standard and available in sizes from DN50 to DN200, is engineered to meet the stringent requirements of offshore and marine oil transportation systems. With an annual export value reflecting our global reach and commitment to quality, we offer valves that ensure safety, durability, and optimal performance in critical pipeline operations.
This gate valve is specifically crafted for the rigorous environment of marine oil pipelines, where reliability is non-negotiable. Its design prioritizes secure shut-off, minimal pressure drop, and long service life, making it a trusted component for shipboard systems, loading arms, and subsea pipelines. As a manufacturer with ISO9001 certification, we maintain strict quality control throughout our production process, ensuring every valve meets international standards and our customers' expectations.
Key Features & Technical Advantages:
- Rugged Construction: The valve body is typically manufactured from high-grade cast steel or cast iron, providing excellent resistance to corrosion and mechanical stress commonly encountered in marine environments.
- Precise Sealing: Features a metal-to-metal seated design (wedge and seat) that ensures a bubble-tight shut-off, crucial for preventing hydrocarbon leaks and ensuring environmental safety.
- Standard Compliance: Full adherence to DIN 3352 specifications guarantees dimensional interchangeability, reliable performance metrics, and compatibility with existing pipeline infrastructure in international markets.
- Wide Size Range: Available from DN50 (2") to DN200 (8"), offering flexibility for various pipeline diameters and flow capacity requirements within oil transfer systems.
- Low Flow Resistance: The full-bore design of the gate valve minimizes turbulence and pressure drop when fully open, promoting efficient fluid transfer and reducing pumping costs.
- Robust Operation: Equipped with a handwheel for manual operation, designed for smooth opening and closing even under high differential pressures. The stem is protected from environmental corrosion.
- Versatile Application: While optimized for marine oil pipelines, this valve is also suitable for onshore crude oil transfer stations, refinery feed lines, and other industrial hydrocarbon services.

Frequently Asked Questions (FAQ):
Q1: What is the primary advantage of using a gate valve in marine oil pipelines instead of other valve types?
A: Gate valves are preferred for their straight-through, full-bore design which offers minimal flow resistance when open, making them highly efficient for transfer lines. Their metal-seated, rising stem design provides a very reliable and positive shut-off, which is critical for safety in oil handling.
Q2: Does compliance with DIN 3352 mean the valve is only suitable for European projects?
A: Not at all. DIN 3352 is an internationally recognized standard for gate valves. Compliance ensures specific dimensions, pressure ratings, and material specifications, making the valve compatible with a wide range of global piping standards and suitable for projects worldwide.
Q3: Can these valves be supplied in materials other than cast steel for corrosive service?
A: Yes. While cast steel (WCB) is standard for general service, we can provide valves in materials like stainless steel (CF8/CF8M), duplex stainless steel, or with special coatings upon request to handle more corrosive crude oils or seawater-contaminated services.
Q4: Are these valves suitable for subsea applications?
A: The standard design is for above-waterline or onboard marine use. For subsea applications, specific design modifications concerning pressure housing, corrosion protection, and actuation would be required. We recommend consulting with our engineering team for such customized requirements.
Q5: What is the typical delivery lead time for an order of DN150 valves?
A: Lead times vary based on order quantity, material specifications, and current production schedule. Standard material valves in common sizes often have shorter lead times. Please contact our sales team with your specific requirements for an accurate delivery estimate.
Q6: Do you provide actuation options for remote operation?
A: Absolutely. While supplied as manual handwheel operated valves, we can equip them with electric, pneumatic, or hydraulic actuators as per your control system requirements. Gear operators are also available for larger sizes to reduce manual effort.
Q7: What pressure testing is performed on these valves before shipment?
A: Each valve undergoes rigorous factory testing, which typically includes shell strength tests (hydrostatic pressure) and seat leakage tests (usually with water or air as per standard practice) to ensure integrity and sealing performance before dispatch.
Q8: Can I get valves with different flange standards, like ANSI, to match my existing piping?
A: Yes, customization is a key service. We can manufacture valves with flanges conforming to ANSI, JIS, or other standards as required. Please specify your flange rating (e.g., ANSI 150#) and facing (RF, FF) when inquiring.
