As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Flanged DIN 3352 Gate Valve in 316 Stainless Steel. Engineered for demanding industrial applications, this full-port, PN25-rated valve combines robust construction with precise performance. Since our establishment in 2016, we have focused on delivering superior fluid control solutions, and this valve exemplifies our dedication to meeting the stringent requirements of global markets. It is designed to provide exceptional shut-off capability, durability, and ease of operation, making it a dependable choice for your critical piping systems.
This valve is built to deliver long-lasting performance and safety in a wide range of industrial environments. Its key features and benefits are detailed below.
Core Features & Technical Advantages:
- Superior Material Construction: Manufactured from high-grade 316 stainless steel, the valve offers excellent resistance to corrosion, pitting, and crevice corrosion, especially in environments containing chlorides. This makes it suitable for chemical processing, marine applications, and food & beverage industries.
- Full Port Design: The full-bore configuration ensures minimal pressure drop across the valve when fully open, allowing for maximum flow capacity and reduced energy consumption in pumping systems. It also facilitates easy cleaning and pigging in pipeline applications.
- Robust Flanged Connection: The flanged ends are precision-machined according to standard dimensions, ensuring a leak-proof and secure connection to the pipeline. This design simplifies installation and maintenance.
- DIN 3352 Compliance: Adherence to the DIN 3352 standard guarantees consistent dimensions, pressure ratings, and material specifications, ensuring interchangeability and reliability within European and international piping systems.
- PN25 Pressure Rating: With a nominal pressure rating of PN25 (approximately 25 bar), this valve is capable of handling high-pressure applications commonly found in water supply, oil & gas, and industrial plant systems.
- Rising Stem Design: The outside screw and yoke (OS&Y) or non-rising stem options provide a visual indication of the valve position (open/closed), enhancing operational safety and control.
- Bidirectional Sealing: The gate valve provides tight sealing in both flow directions, ensuring reliable isolation of the pipeline section.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of using 316 stainless steel over 304 for this gate valve?
A1: 316 stainless steel contains molybdenum, which significantly enhances its resistance to corrosion from chlorides and other aggressive chemicals. This makes it a more suitable choice for marine environments, chemical processing, and applications where media may cause pitting or crevice corrosion.
Q2: Can this valve be used for throttling or flow control?
A2: Gate valves are primarily designed for isolation (fully open or fully closed), not for precise flow regulation or throttling. Using them for throttling can cause seat and disc erosion, leading to leakage. For flow control applications, consider our globe or control valves.
Q3: Are the flanges drilled according to specific standards like DIN or ANSI?
A3: Yes. Our standard offering includes flanges drilled to DIN PN16/PN25 standards. However, we can customize the flange drilling pattern (e.g., ANSI 150/300) and facing (RF, FF) upon request to match your existing pipeline specifications.
Q4: What is the delivery time for a standard order of these valves?
A4: For standard sizes and configurations, our typical lead time is 4-6 weeks. Expedited production may be available for urgent requirements. We recommend contacting our sales team with your specific quantity and size details for an accurate delivery schedule.
Q5: Do you offer any other end connections besides flanged?
A5: While the featured product is a flanged valve, we manufacture gate valves with various end connections, including butt-weld (BW), socket-weld (SW), and threaded (NPT, BSP). Please inquire for these alternative configurations.
Q6: Is the valve suitable for steam service?
A6: Yes, within its specified temperature range of up to 200°C, this valve can handle saturated steam applications. For higher temperature steam services, please consult with our engineering team to ensure material suitability and potential design modifications.
Q7: What type of packing is used in the stem sealing area?
A7: The valve is typically equipped with graphite or PTFE-based stem packing suitable for the stated temperature and media range. The exact packing material can be selected based on your specific service conditions to ensure optimal sealing performance and longevity.
Q8: Do you provide testing and inspection certificates with the valves?
A8: Yes. Standard delivery includes a manufacturer's test certificate. Additional inspections and certifications, such as Third-Party Inspection (TPI) or specific material test reports (MTR), can be arranged upon request and may incur additional charges.
