As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DIN 3352 PN10 Gate Valve with Non-Rising Stem. Engineered specifically for demanding oil and gas applications, this valve is built to deliver dependable shut-off performance, ensuring safe and efficient operation in your critical pipelines. Our years of experience since 2016 in serving global markets across North America, Europe, Asia, and beyond have honed our expertise in producing valves that meet international standards and withstand rigorous service conditions. This gate valve represents our dedication to providing robust solutions that enhance operational integrity and minimize maintenance downtime for our clients worldwide.
The core design of this valve focuses on durability and ease of use in space-constrained installations. The non-rising stem mechanism is a key feature, offering significant advantages in applications where vertical space is limited or where stem exposure could pose a safety or contamination risk. Unlike rising stem valves, the handwheel and stem nut rotate without the stem moving vertically, keeping the overall valve height constant during operation. This design is particularly beneficial for underground installations, manifold systems, and locations with overhead obstructions.
Detailed Features and Technical Advantages:
- Robust Construction for Harsh Environments: Manufactured from high-grade materials such as cast steel WCB or ductile iron, the valve body is designed to handle the pressures and corrosive elements often present in oil and gas service. The internal components are precision-machined to ensure a tight seal and smooth operation.
- Reliable Sealing Performance: Features a metal-to-metal seat design (standard) that provides excellent sealing capabilities for a wide range of media, including crude oil, natural gas, refined products, and water. The wedge is meticulously machined and matched to the seat rings to achieve bubble-tight shut-off when required.
- Space-Efficient Design: The non-rising stem is the ideal choice for applications where vertical clearance is an issue. The entire actuation mechanism is contained within the yoke, making the valve suitable for pits, tunnels, and crowded valve racks.
- Easy Operation and Maintenance: Equipped with a handwheel that provides good mechanical advantage for opening and closing. The stem threads are protected from the line media, reducing wear and corrosion and extending service life. Gland packing is easily adjustable for maintaining seal integrity.
- Versatile Application Scope: While optimized for oil and gas pipelines, this PN10 rated valve is also suitable for other industrial services such as steam, water treatment, and chemical processing where a pressure rating of 10 bar is required.
- Standard Compliance: Designed and manufactured in accordance with DIN 3352 standards for flanged gate valves, ensuring dimensional interchangeability and compatibility with other DIN-standard piping components in international projects.

Benefits to Your Operation:
- Enhanced Safety: The contained non-rising stem design minimizes external moving parts, reducing the risk of injury and containing any potential leakage within the gland area.
- Reduced Maintenance Costs: The protected stem threads and robust construction lead to longer service intervals and lower lifetime costs.
- Installation Flexibility: Allows for installation in locations with limited overhead space, providing greater design freedom for engineers and project planners.
- Global Project Compatibility: Adherence to DIN standards makes this valve a reliable choice for international projects, especially in European, Asian, and Middle Eastern markets where these standards are prevalent.
- Consistent Performance: Precision manufacturing under our ISO9001 certified quality management system ensures every valve delivers reliable and repeatable shut-off performance.
Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a non-rising stem gate valve over a rising stem type?
A: The primary advantage is its compact vertical profile. The stem does not move upward when opening, making it ideal for installations with limited vertical space, such as underground vaults or areas with low overhead clearance. It also helps keep the stem threads clean and protected. -
Q: Is this valve suitable for natural gas distribution pipelines?
A: Yes, it is designed for oil and gas service, including natural gas. The metal-seated design provides a reliable seal for gaseous media. Material selection (e.g., carbon steel) should be confirmed based on the specific gas composition and pressure. -
Q: What does the PN10 pressure rating mean?
A: PN10 indicates a nominal pressure rating of 10 bar at ambient temperature (around 20°C). This is a common rating for many water, oil, and low-pressure gas applications. The valve is designed to safely handle pressures up to this level. -
Q: Can this valve be used for throttling or flow control?
A: Gate valves, including this model, are primarily designed for isolation (fully open or fully closed) and are not recommended for throttling service. Using them for flow control can cause vibration, wire drawing on the seat, and premature wear. -
Q: What flange facing is provided on these valves?
A> As per DIN 3352 standards for PN10, the flanges typically have a raised face (RF). The specific flange standard (e.g., DIN EN 1092-2) and facing details can be confirmed for your order to ensure compatibility with your piping. -
Q: Are other actuator options available besides the manual handwheel?
A> Yes. While supplied with a standard handwheel, this valve can be fitted with various actuators such as electric, pneumatic, or hydraulic actuators upon request for automated operation. -
Q: What is the lead time for orders of this valve?
A> Lead times vary based on size, material, and order quantity. As an established manufacturer with an annual export value in the range of US$1-1.5 million, we maintain efficient production scheduling. Standard sizes and materials often have shorter lead times, which can be confirmed upon inquiry. -
Q: Do you provide full certification and testing documentation?
A> Yes. Our manufacturing process is ISO9001 certified, ensuring consistent quality control. Standard documentation includes a material test certificate, pressure test report, and full dimensional drawings. Additional certifications can be discussed as needed.
