DIN 3352 Marine Gate Valve in Cast Iron, Flanged Connection for Shipboard Piping
Product Spotlights
As a professional manufacturer of industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our robust DIN 3352 Marine Gate Valve. Engineered specifically for the demanding marine environment, this cast iron, flanged gate valve is designed to deliver reliable isolation and flow control in shipboard piping systems. Our commitment to ISO9001 certified quality management ensures that every valve meets stringent standards for durability and performance, providing shipbuilders and marine engineers with a trustworthy component for critical applications. With extensive export experience to global markets including North America, Europe, and Southeast Asia, we understand the precise requirements for marine-grade equipment.
This valve is a cornerstone for managing fluid flow onboard vessels. Its primary function is to provide a tight shut-off, ensuring safety and operational efficiency in various systems.
Key Features & Technical Advantages:
- Rugged Cast Iron Construction: The valve body and bonnet are manufactured from high-grade cast iron, offering excellent corrosion resistance and mechanical strength to withstand harsh marine conditions, including exposure to seawater and varying temperatures.
- DIN 3352 Standard Compliance: Manufactured in accordance with DIN 3352 standards, ensuring dimensional compatibility, performance reliability, and interchangeability with other compliant components in European and international marine projects.
- Flanged Connection for Secure Mounting: Features flanged ends conforming to standards such as DIN EN 1092-2, facilitating a robust, leak-proof connection to the ship's piping network. This design allows for easier installation, maintenance, and replacement.
- Metal Seat Design: Utilizes a metal-to-metal seating arrangement, which provides superior sealing integrity and longevity compared to soft-seated alternatives, especially important for handling various media at different pressures and temperatures.
- Rising Stem with Visual Position Indicator: The outside screw and yoke (OS&Y) design features a rising stem. The position of the stem provides a clear, visual indication of whether the valve is open or closed, a critical safety feature in marine operations.
- Robust Operation: Equipped with a handwheel for manual operation, designed for smooth actuation even under high differential pressures. The sturdy construction minimizes the risk of seizure or operational failure.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for seawater applications?
A: Yes. The cast iron construction provides good corrosion resistance, making it suitable for handling seawater, ballast water, and other marine fluids. For specific highly corrosive media, alternative material options can be discussed. -
Q: What flange facing and drilling standards are available?
A: Our standard offering complies with DIN EN 1092-2 for PN10/16 flanges. However, we can customize the flange facing (e.g., raised face) and drilling pattern to meet other international standards like ANSI/ASME, JIS, or BS upon request. -
Q: Can this valve be operated remotely or automatically?
A: The standard configuration is manual operation via a handwheel. For automated control, we can provide options for fitting with electric, pneumatic, or hydraulic actuators. Please inquire about actuation solutions. -
Q: What is the typical delivery time for this product?
A: For standard sizes and specifications, we generally maintain stock for prompt shipment. Delivery times vary based on order quantity and customization. We provide accurate lead times upon order confirmation. -
Q: Do you offer different size ranges for this DIN 3352 valve?
A: Yes. We produce this marine gate valve in a range of nominal diameters (DN) commonly used in shipboard piping. Please contact us with your required size for availability and pricing. -
Q: How does the metal seat perform compared to soft seats?
A: Metal seats offer superior resistance to erosion, high temperatures, and certain chemicals compared to elastomer soft seats. They provide a durable, long-lasting seal, ideal for abrasive or high-temperature media found in marine systems, though they may not achieve the same bubble-tight seal as soft seats at lower pressures. -
Q: What pressure classes (PN) are available beyond PN16?
A> While PN10 and PN16 are standard, we have the capability to manufacture valves for higher pressure ratings, such as PN25 or PN40, using appropriate material grades and designs. These would be considered custom orders. -
Q: What documentation and certifications accompany the valve?
A> Each valve can be supplied with standard documentation including a material certificate and a test certificate (e.g., hydrostatic test). Our manufacturing facility is ISO9001 certified, ensuring consistent quality control processes.
