As a dedicated manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-quality industrial valves for global markets. Our DIN 3352 Standard Cast Iron Gate Valve with Non-Rising Stem and Manual Operation represents our commitment to reliability, durability, and precise flow control in demanding industrial environments. Engineered for longevity and robust performance, this valve is an essential component for systems requiring complete shut-off capabilities.
This gate valve is meticulously designed to meet the rigorous DIN 3352 standard, ensuring compatibility and performance in a wide range of industrial applications. Its construction and features offer significant advantages for pipeline management.
- Durable Cast Iron Body: The valve body is constructed from high-grade cast iron, providing excellent resistance to corrosion and wear, making it suitable for water, oil, gas, and steam services.
- Non-Rising Stem Design: A key feature that enhances safety and simplifies installation in confined spaces. The stem does not ascend during operation, maintaining a consistent external profile.
- Manual Handwheel Operation: Features a robust, ergonomically designed handwheel for reliable and straightforward open/close control, requiring no external power source.
- Metal-to-Metal Sealing: The wedge and seat utilize metal sealing surfaces, ensuring a tight, leak-proof shut-off even after prolonged use and in high-pressure scenarios.
- Flanged Connection: Standard flanged ends (as per DIN 2501) facilitate secure and leak-free installation into pipeline systems, compatible with common flange standards.
- Versatile Application: Ideal for use in water supply networks, wastewater treatment, heating systems, general industrial pipelines, and shipbuilding where on/off service is critical.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a non-rising stem in this gate valve?
A: The non-rising stem design means the stem threads are inside the valve body. The handwheel and stem nut rotate to move the gate, but the stem's height does not change. This is advantageous for installations with limited vertical space or where stem exposure could be a safety or contamination concern.
Q2: Is this valve suitable for steam service?
A: Yes, within its specified temperature range of up to 120°C, this cast iron gate valve can be used for saturated steam applications. For higher temperature steam, alternative materials like cast steel may be recommended.
Q3: Can you provide valves with different end connections besides flanged?
A: The standard offering for DIN 3352 gate valves is flanged ends. However, as a manufacturer, we can explore customized connection options such as threaded ends upon request, depending on order quantity and specific requirements.
Q4: What pressure ratings (PN) are available for this valve?
A: This valve model is typically available in standard pressure ratings of PN10 and PN16, which correspond to 10 bar and 16 bar nominal pressures, respectively. The specific rating should be confirmed based on your system requirements.
Q5: How does the manual operation handle large-size valves?
A: For larger valve sizes, the handwheel is designed with a sufficient diameter to provide the necessary mechanical advantage for easier operation. In some cases, a gearbox operator can be supplied as an optional accessory to further reduce the required operating torque.
Q6: What maintenance does this cast iron gate valve require?
A: These valves are designed for low maintenance. Periodic checks of the gland packing for tightness and occasional lubrication of the stem threads (if accessible) are generally recommended to ensure smooth operation over its long service life.
Q7: Are spare parts like the wedge or gland packing available?
A: Yes, as the manufacturer, we maintain an inventory of critical spare parts for our valves. Customers can procure replacement wedges, seats, stem packing sets, and other components to extend the valve's lifespan.
Q8: Do you offer any testing or inspection reports for the valves?
A> Standard production valves undergo routine quality checks. For specific projects, additional testing such as shell tests, seat tests, or material certification can be arranged and provided upon request, subject to applicable charges.
