As a leading manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance valves for demanding global markets. Our CB/T3591 Ductile Iron Marine Gate Valve represents our commitment to reliability and durability in marine and industrial applications. Engineered with a robust flanged design and a PN16 pressure rating, this valve ensures secure shut-off and long service life in critical fluid control systems. We combine stringent quality control under our ISO9001 certification with extensive export experience, serving clients across North America, Europe, Asia, and beyond, to deliver products you can trust for your essential operations.
Core Product Features & Technical Advantages:
- Superior Durability: Manufactured from high-grade ductile iron, the valve body and major components offer exceptional strength and resistance to pressure surges, making it suitable for a wide range of media including water, oil, and gas in marine environments.
- Non-Rising Stem Design: This design is a key feature for space-constrained installations. The stem threads into the gate, so the handwheel does not rise during operation, saving vertical space and allowing for easier operation in tight areas.
- Flanged Connection Excellence: Precision-machined flanges ensure a leak-proof connection to the pipeline, facilitating easy installation, maintenance, and a secure seal that withstands the PN16 pressure rating.
- Wide Size Compatibility: Available in a comprehensive range from DN50 to DN300, this valve series can accommodate various pipeline diameters, providing a versatile solution for different system requirements.
- Smooth Operation & Reliable Sealing: The internal wedge gate mechanism is designed for low-friction operation, ensuring easy opening and closing even after prolonged periods. Paired with quality sealing materials, it guarantees effective shut-off.

Frequently Asked Questions (FAQ):
-
Q: What does "Non-Rising Stem" mean, and what is its advantage?
A: In a non-rising stem gate valve, the stem threads are inside the valve body. When you turn the handwheel, the gate moves up or down, but the stem itself does not rise out of the valve. The primary advantage is that it requires less vertical installation space compared to rising stem valves. -
Q: Is this valve suitable for seawater applications?
A: The ductile iron body provides good general corrosion resistance. For prolonged seawater service, specifying appropriate internal trim materials (such as bronze or stainless steel) and external coatings is recommended. Please consult our team for specific media compatibility. -
Q: What flange standards are available?
A: Our valves are typically supplied with flanges machined to common international standards such as ISO, DIN, or ANSI/ASME. The specific standard and facing (e.g., RF, FF) can be specified at the time of ordering to match your existing pipeline. -
Q: Can this valve be used for throttling flow?
A: Gate valves are primarily designed for fully open or fully closed service (on/off). Using them for frequent flow throttling can cause vibration and damage to the seating surfaces, leading to premature wear and leakage. They are not recommended for throttling purposes. -
Q: What is the lead time for an order of DN200 valves?
A: Lead times vary based on order quantity and current production schedule. Generally, for standard sizes like DN200, we can arrange shipment promptly. We ship from multiple ports including Shanghai and Guangzhou for flexibility. -
Q: Do you provide documentation like test certificates?
A: Yes, as an ISO9001-certified manufacturer, we can provide standard factory test reports for our valves, which typically include shell test and seat leak tests. Detailed certification is available upon request. -
Q: What is the main application of a PN16 rated valve?
A> A PN16 pressure rating indicates the valve is designed to withstand a nominal pressure of 16 bar at ambient temperatures. It is commonly used in a wide array of industrial and marine water supply, cooling, drainage, and other general service systems where this pressure range is standard. -
Q: Are other end connections besides flanged available?
A> The product described here is specifically designed with flanged ends as per the CB/T3591 standard. For other connection types like threaded (screwed) ends, we offer different product series. Please inquire about your specific connection requirement.
