Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a dedicated manufacturer specializing in high-quality industrial valves. With an annual export value exceeding US$1 million, we have built a solid reputation across diverse markets, including North America, Southeast Asia, Europe, and Africa. Our Ductile Iron Gate Valve, compliant with CB/T3591-2005, embodies our commitment to reliability and performance. Designed with a non-rising stem and manual operation, this valve offers a robust, durable, and user-friendly solution for controlling fluid flow in demanding industrial environments.

This gate valve is engineered for long-term service in pipeline systems handling water, oil, and gas. Its core advantages lie in its sturdy construction, ease of operation, and adherence to stringent Chinese national standards, ensuring compatibility and safety in a wide range of applications.

Detailed Features & Technical Specifications:

Robust Material Construction: The valve body and key components are crafted from ductile iron, providing superior strength, impact resistance, and durability compared to standard cast iron. This material choice significantly enhances the valve's lifespan under high-pressure conditions.
Non-Rising Stem Design: This innovative design means the stem does not extend upwards during operation. It offers a compact profile, reduces the required installation space, and minimizes the risk of stem damage or corrosion from external exposure, making it ideal for buried or confined pipeline layouts.
Manual Operation Simplicity: The valve is operated via a handwheel, offering straightforward and reliable on/off control without the need for complex power systems. This design is cost-effective, easy to maintain, and suitable for locations where automated control is not necessary.
CB/T3591-2005 Compliance: Manufactured in strict accordance with the Chinese technical standard for iron gate valves, this product guarantees consistent quality, dimensional accuracy, and performance metrics that meet recognized industry benchmarks.
Excellent Sealing Performance: The valve utilizes a precision-machined gate and seat arrangement to ensure tight shut-off, minimizing leakage and ensuring efficient flow isolation when closed.
Flanged End Connections: Standard flanged ends facilitate secure and leak-proof installation into pipeline systems, compatible with common piping flanges.
Wide Application Range: Suitable for a variety of media including clean water, oil, and natural gas within specified temperature and pressure limits.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of a non-rising stem design?
A: The primary advantage is its compactness. The stem does not move vertically out of the valve body during operation, which saves installation space and protects the stem from environmental corrosion or physical damage, especially in buried pipelines.
Q: Is this valve suitable for steam applications?
A: Based on the specified temperature range (0°C to 120°C), this valve is not recommended for high-temperature steam services. It is designed for water, oil, and gas applications within its rated temperature limit.
Q: Can the valve be operated with an actuator for automated control?
A: This specific model is designed for manual operation via a handwheel. For automated control, you would need to inquire about valves with a different stem design compatible with actuators, which may be available as a customizable option.
Q: What does compliance with CB/T3591-2005 mean for me?
A: It means the valve's dimensions, material requirements, pressure ratings, and testing methods conform to this Chinese national technical standard. This ensures predictable performance and compatibility in systems where this standard is referenced or required.
Q: Are other end connection types available besides flanged?
A: The standard offering for this valve series is flanged ends. Other connection types, such as threaded, may be available upon request as a custom modification, subject to feasibility and order quantity.
Q: What is the difference between ductile iron and cast iron in valve bodies?
A: Ductile iron has higher tensile strength and better impact resistance than cast iron due to its microstructure. It is more flexible and durable, making it a preferred material for valves in demanding pressure conditions.
Q: What pressure ratings (PN) are typically available?
A: This valve series is commonly available in pressure ratings of PN10, PN16, and PN25. The specific rating for a given size can be confirmed based on your application requirements.
Q: Does your company provide testing reports or certifications for the valves?
A: As an ISO9001 certified manufacturer, we conduct standard quality tests. Specific test reports or certificates can be provided upon request, detailing parameters like pressure testing and material analysis.
