As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in producing high-performance marine valves for global clients. Our OEM Marine Gate Valve compliant with DIN 3352 standard and featuring a flanged end is engineered to meet the rigorous demands of marine and industrial applications. Designed for reliable shut-off service in pipelines carrying seawater, ballast, fuel, and other fluids, this valve offers robust construction, smooth operation, and long-term durability, making it a trusted component for shipbuilders, shipyards, and offshore platform operators worldwide.
This gate valve is manufactured under our ISO9001 certified quality management system, ensuring consistent quality and performance in every unit. We understand the critical role valves play in marine systems, where failure is not an option. Therefore, our design prioritizes:
- Leak-tight sealing to prevent fluid loss and ensure system integrity.
- Corrosion resistance for extended service life in harsh marine environments.
- Easy operation and maintenance to reduce downtime and operational costs.
- Full compliance with international standards for global acceptance and compatibility.
Detailed Product Features & Technical Specifications:
Our marine gate valve is meticulously designed according to the DIN 3352 standard, which specifies requirements for cast iron and cast steel gate valves. The flanged end connection ensures a secure, bolted joint that is standard across marine and industrial piping systems, facilitating easy installation and replacement.
Core Design & Construction Advantages:
- Robust Body Construction: The valve body is typically cast from materials like cast steel (WCB), cast iron, or stainless steel (CF8/CF8M) to withstand high pressures and corrosive media. Material selection can be customized based on the specific fluid and service conditions.
- Rising Stem Design (OS & Y): Features an outside screw and yoke (OS&Y) design. The stem rises as the valve is opened, providing a clear visual indication of the valve position (open or closed), which is a critical safety feature.
- Superior Sealing Mechanism: Utilizes a wedge or parallel slide disc that mates precisely with the valve seats. Seat materials like bronze or stainless steel are selected for excellent wear resistance and reliable, bubble-tight shut-off.
- Flanged Ends per DIN/ANSI/ISO Standards: The flanged ends are machined to precise dimensions, complying with standards like DIN 2501, ANSI B16.5, or ISO 7005, ensuring perfect alignment and sealing with pipeline flanges. Gasket surfaces are finely finished.
- Corrosion Protection: Valves intended for marine service often receive additional surface treatments such as epoxy coating, galvanization, or specialized marine-grade paints to combat saltwater corrosion.
- Versatile Operation: Primarily designed for manual operation via a handwheel, but can be optionally equipped with gear operators, electric actuators, or pneumatic actuators for remote or automated control.

Frequently Asked Questions (FAQ):
-
Q: What does "compliant with DIN 3352" mean for this valve?
A: DIN 3352 is a German industrial standard that specifies the design, dimensions, materials, pressure ratings, and testing requirements for cast iron and cast steel gate valves. Compliance ensures the valve meets recognized international engineering criteria for performance and safety. -
Q: Can this valve be used for applications other than marine?
A: Absolutely. While designed for marine environments, its robust construction and compliance with industrial standards make it suitable for various applications, including power plants, water treatment, oil & gas, and general industrial piping systems. -
Q: What are the available flange standards and face types?
A: The flanges are typically manufactured to DIN/EN standards (like DIN 2501), but can also be produced to match ANSI B16.5 or JIS standards upon request. Common face types are Raised Face (RF) and Flat Face (FF). -
Q: Do you offer different material grades for the body and trim?
A: Yes. We offer a range of materials. Common body materials include cast steel WCB for general service and stainless steel CF8/CF8M (304/316) for corrosive fluids. Trim materials like bronze or stainless steel can be selected based on the fluid compatibility. -
Q: What is the lead time for an OEM order with custom specifications?
A: Lead times vary based on order quantity and customization complexity. Standard sizes may have shorter lead times. We provide a detailed production schedule upon order confirmation to ensure clear communication. -
Q: How do you ensure quality control during manufacturing?
A: Our quality control is integrated into every stage under our ISO9001 system. This includes material certification checks, dimensional inspections during machining, pressure testing (shell and seat tests), and final performance verification before packing. -
Q: Can the valve be equipped with actuators for automated control?
A: Yes. The valve is designed to be compatible with various actuators. We can supply and mount electric or pneumatic actuators based on your control system requirements (voltage, signal type, speed). -
Q: What documentation do you provide with the valves?
A: Standard documentation includes a commercial invoice, packing list, and a certificate of compliance/conformity. Material test certificates (MTC) and detailed inspection reports are available upon request.
