As a dedicated manufacturer with a strong focus on industrial fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T465-1995 Cast Iron Gate Valve featuring a Full Port and Rising Stem Design. Engineered for reliability and durability in demanding pipeline applications, this valve represents our commitment to providing robust and efficient flow control components. Established in 2016 and backed by ISO9001 certification, our production processes ensure consistent quality, making this valve a dependable choice for your systems.
This valve is designed to offer unimpeded flow and straightforward operation. The Full Port design minimizes flow resistance, allowing for maximum fluid throughput, which is crucial for systems requiring efficient transfer. The Rising Stem mechanism provides a clear visual indication of the valve's open or closed status, enhancing operational safety and ease of monitoring. Constructed from cast iron, the valve body offers excellent strength and corrosion resistance, suitable for a wide range of industrial environments.
Key Technical Specifications and Advantages:
- Compliance with CB/T465-1995: Manufactured according to this specific Chinese technical standard, ensuring dimensional accuracy, material properties, and performance criteria are met.
- Robust Construction: The cast iron material provides high tensile strength and good resistance to wear, making it suitable for handling water, oil, gas, and other general industrial fluids.
- Optimized Flow Path: The full port (also known as full bore) design means the valve's internal diameter matches the pipeline diameter, reducing pressure drop and turbulence.
- Clear Operational Feedback: The rising stem moves linearly as the valve is operated. When the stem is up, the valve is open; when it is down, the valve is closed, offering intuitive status checks.
- Flanged Connection: Typically designed for flanged end connections, facilitating secure installation and integration into existing piping networks.
- Manual Operation: Designed for manual operation via a handwheel, providing direct control without the need for auxiliary power sources in many applications.

Frequently Asked Questions (FAQ):
-
Q: What does "CB/T465-1995" signify for this valve?
A: CB/T465-1995 is a Chinese technical standard that specifies the design, dimensions, materials, and testing requirements for marine cast iron gate valves. Compliance ensures the valve meets defined criteria for performance and interoperability in systems adhering to this standard. -
Q: What are the main advantages of a Full Port design?
A: A Full Port (Full Bore) valve has an internal passage diameter equal to the connected pipe's inner diameter. This minimizes flow restriction, reduces pressure loss, allows for easier passage of pipeline cleaners, and generally provides higher flow capacity compared to reduced port valves. -
Q: How does the Rising Stem (OS&Y) design benefit operation?
A: The Rising Stem, or Outside Stem & Yoke (OS&Y), design means the stem moves upward as the valve opens. This provides a clear, visual indication of the valve's status (open/closed) from a distance, enhancing operational safety and simplifying inspection procedures. -
Q: Is cast iron suitable for corrosive fluids?
A: Cast iron offers good general corrosion resistance for many industrial fluids like water, oil, and gas. For highly corrosive media, specific material grades or internal coatings may be considered. We can advise on material suitability based on your application details. -
Q: What pressure ratings and sizes are available?
A: Pressure ratings (like PN10, PN16) and nominal diameters (DN sizes) are customizable based on your project needs. Please provide your required specifications for us to confirm availability or manufacturing options. -
Q: Can this valve be automated or fitted with actuators?
A: This design is primarily for manual operation via a handwheel. For automated control, it may be possible to adapt it with a suitable actuator bracket, but this would be a customized solution. We recommend discussing your automation requirements with our technical team. -
Q: What end connection types are offered?
A: These valves are typically supplied with flanged ends according to common flange standards (like GB, ANSI, DIN). The specific flange standard, face type, and dimensions can be customized to match your piping system. -
Q: What is the typical delivery time?
A: Delivery time depends on order quantity, specific customization requirements, and current production schedule. Standard configurations may have shorter lead times. We provide estimated timelines upon receipt of your detailed inquiry.
