As a leading manufacturer with ISO9001 certified production processes, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DIN 3352 Ductile Iron Flanged Gate Valve. Engineered for reliability in demanding industrial applications, this valve combines robust construction with precise flow control. Our years of experience since 2016, backed by an annual export value reaching up to US$1.5 million, ensure that each valve meets stringent quality standards for global markets including North America, Europe, and Southeast Asia. The non-rising stem design is a key feature, offering space-saving installation and enhanced safety in confined areas.
This gate valve is designed for on/off service in pipeline systems, providing a tight shut-off for liquids and gases. Its flanged ends ensure a secure, leak-proof connection compatible with standard piping networks.
Key Features & Technical Advantages:
- Robust Ductile Iron Construction: The valve body is made from high-grade ductile iron (also known as nodular cast iron), which offers superior tensile strength and impact resistance compared to standard cast iron. This material provides excellent durability against water hammer and pressure surges.
- Space-Efficient Non-Rising Stem Design: Unlike rising stem valves where the stem extends upwards during operation, the stem threads are contained within the valve body. This design is ideal for installations with limited vertical space or where stem exposure could pose a safety or contamination risk.
- DIN 3352 Compliance: Manufactured in accordance with DIN 3352 standards, ensuring dimensional accuracy, performance consistency, and interchangeability with other compliant valves in the pipeline.
- Dual Pressure Rating Flexibility: Rated for both PN10 (10 bar) and PN16 (16 bar) pressure classes, offering versatility for use in various system pressure requirements within water supply, industrial processing, and building services.
- Reliable Sealing System: Features a wedge disc that provides a tight seal against the valve body seats. Seat ring materials are customizable (e.g., EPDM, NBR, PTFE) to match specific media compatibility needs for water, oil, gas, or steam services.
- Corrosion-Resistant Stem: The stem is typically manufactured from stainless steel (2Cr13 or equivalent), providing resistance to corrosion and ensuring smooth, long-term operation without seizing.
- Standard Flanged Ends: Equipped with EN 1092-1 (DIN) standard flanges, facilitating easy bolt-on installation and replacement within existing flanged piping systems.
- Easy Operation & Maintenance: Designed for manual operation with a handwheel. The compact design and enclosed stem mechanism reduce the need for frequent maintenance and protect internal components from environmental contaminants.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a non-rising stem design compared to a rising stem gate valve?
A: The primary advantage is space savings. Since the stem does not move vertically outside the valve body, it requires less installation height. This makes it suitable for confined spaces like valve boxes, tunnels, or areas with overhead obstructions. It also keeps the stem threads protected inside the valve, potentially reducing maintenance. -
Q: Can this PN10/PN16 valve be used for both cold water and steam applications?
A: Yes, the valve body and pressure rating are suitable for both. However, the maximum temperature is determined by the seat seal material (e.g., EPDM for lower temps, PTFE or metal for higher). It is crucial to specify the operating media and temperature when ordering to ensure the correct seal material is fitted. -
Q: Are the flanges compatible with ANSI/ASME standard piping?
A: The flanges conform to the EN 1092-1 (DIN) standard, which has different dimensions and bolt patterns compared to ANSI/ASME B16.5 flanges. For connection to ANSI piping, adaptor flanges or a different valve model designed to ANSI standards would be required. Please inquire about ANSI-specific models if needed. -
Q: What is the typical lead time for this valve, and what are the available sizes?
A: Standard sizes (e.g., DN50 to DN300) are often available from stock or with short lead times. Larger or special configurations may require a manufacturing cycle. Specific lead times and size availability can be confirmed upon request with your desired specifications. -
Q: Does the valve come with any operational indicators since the stem doesn't rise?
A: Non-rising stem valves typically indicate position via the handwheel rotation. A common practice is to mark the handwheel or use a pointer to show "Open" and "Closed" positions. Some models can be fitted with a visual position indicator as an optional accessory. -
Q: Is the valve suitable for underground or buried service?
A: Yes, the non-rising stem design is particularly advantageous for buried service as there is no exposed stem to corrode or be damaged. For direct burial, specifying an appropriate epoxy coating or other corrosion protection for the valve exterior is recommended. -
Q: What quality certifications does Shanghai Zhibang Valve hold for this product?
A: Our manufacturing facility is ISO9001 certified, ensuring a controlled quality management system for design, production, and testing. Specific product certifications (like CE-PED for pressure equipment) can be discussed based on project requirements and destination market regulations. -
Q: Can the valve be automated with an electric or pneumatic actuator?
A: Absolutely. This non-rising stem gate valve can be fitted with various actuators for remote or automated control. The design allows for direct mounting of quarter-turn actuators. Please provide your automation requirements for a compatible actuator package solution.
