As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for demanding applications. Our DIN 3352 F4/F5 Face-to-Face Dimension Marine Gate Valve is engineered to meet the rigorous standards of the marine and shipbuilding industry, offering reliable flow control in critical onboard and offshore systems. With years of experience since our establishment in 2016 and a strong export presence across continents, we understand the need for valves that combine durability, precise dimensions, and compliance with international norms.
This valve is designed specifically for OEM applications, ensuring seamless integration into your marine equipment and systems. Its construction prioritizes longevity and maintenance-free operation in saltwater and harsh marine environments, providing peace of mind for ship operators and builders.
Core Product Features & Technical Advantages:
- Standardized Dimensions: Strict adherence to DIN 3352 F4/F5 face-to-face dimensions ensures perfect compatibility and easy replacement within existing piping systems, eliminating installation guesswork.
- Robust Marine-Grade Construction: Manufactured from materials selected for superior corrosion resistance against seawater, including cast steel, ductile iron, or stainless steel options.
- Superior Sealing Performance: Features a precision-machined seat and wedge (often stainless steel or bronze) that provides a bubble-tight seal, minimizing leakage and ensuring safe isolation.
- Versatile Pressure Handling: Available in standard pressure classes like PN10, PN16, and PN25, suitable for a wide range of shipboard services from ballast and bilge systems to cooling lines.
- Multiple Operation Methods: Can be supplied with standard handwheels, gear operators for high-torque applications, or automated actuators for remote control integration.
- Rising Stem Design: The visual indication of the stem position allows for clear, at-a-glance status confirmation of whether the valve is open or closed.

Frequently Asked Questions (FAQ):
Q1: What does "Face-to-Face Dimension F4/F5" specifically mean for installation?
A1: It refers to the standardized length between the two flange faces of the valve as per DIN 3352. F4 and F5 are specific dimension series. This standardization ensures the valve will fit perfectly into the pipeline spacing designed for these standards, making installation and replacement straightforward.
Q2: Can this valve be used with fluids other than seawater?
A2: Absolutely. While optimized for marine service, its robust construction makes it suitable for a variety of industrial fluids including oil, gas, steam (depending on pressure/temp ratings), and other corrosive or abrasive media, provided the material selection is appropriate.
Q3: Do you offer actuators for automated operation?
A3: Yes, we can supply the valve prepared for the mounting of electric, pneumatic, or hydraulic actuators. This is a common customization for OEMs requiring remote or automated control systems.
Q4: What is the typical lead time for an OEM order?
A4: Lead time depends on order quantity, material specifications, and customization level. For standard configurations in moderate quantities, production typically takes 4-8 weeks. We provide accurate timelines with every quotation.
Q5: How do you ensure corrosion resistance for long-term marine use?
A5: We select materials with inherent corrosion resistance (e.g., stainless steel) and apply protective coatings like epoxy or galvanization on carbon steel bodies as specified. The stem packing and sealing materials are also chosen to withstand saline environments.
Q6: Can you provide valves with certificates like Material Test Reports (MTRs)?
A6: Yes, upon request, we can supply relevant documentation including material test certificates, pressure test reports, and certificates of conformity, which are often required for marine classification society approvals.
Q7: What is the difference between rising stem and non-rising stem designs?
A7: A rising stem gate valve has a stem that moves up and down with the gate, providing a visual indication of valve position. A non-rising stem valve's stem rotates but does not move axially, which is useful where vertical space is limited. Both are available.
Q8: Do you offer a warranty on your marine gate valves?
A8: We stand behind the quality of our products. Specific warranty terms are provided with the commercial contract, typically covering manufacturing defects for a defined period under normal use and service conditions.
