As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T467 series Bronze Gate Valves, engineered for demanding marine and industrial applications. Since our establishment in 2016, we have focused on delivering reliable flow control solutions, and this valve series exemplifies our commitment to quality and technical precision. Designed to meet the stringent CB/T467 marine standard, these valves offer robust performance, exceptional durability, and precise shut-off capabilities, making them a trusted choice for shipbuilders, offshore platforms, and various industrial piping systems worldwide.
The core value of our CB/T467 Bronze Gate Valve lies in its combination of marine-grade construction and versatile functionality. The use of high-quality bronze material ensures excellent corrosion resistance, particularly against seawater and other harsh media, while providing superior mechanical strength. The valve's design facilitates a full-port opening, minimizing pressure drop and allowing for efficient fluid passage. This is crucial for systems where flow efficiency and reliable isolation are paramount. We provide comprehensive technical data sheets with each product, ensuring our clients have all the necessary information for seamless integration into their projects.
Detailed Features & Technical Advantages:
- Marine-Specific Design: Manufactured in strict compliance with the CB/T467 standard, these valves are specifically validated for marine and offshore applications, ensuring safety and reliability in critical environments.
- Premium Bronze Construction: The valve body, bonnet, gate, and stem are crafted from selected bronze alloys, offering proven resistance to corrosion, dezincification, and erosion from seawater, steam, oil, and general service fluids.
- Precise Shut-Off Mechanism: The parallel gate design with either metal-to-metal or optional soft seating provides a bubble-tight seal when fully closed, ensuring zero leakage and safe system isolation.
- Durable Stem & Thread Design: The rising stem design with ACME threads ensures smooth, low-friction operation, precise gate positioning, and long service life even under frequent cycling.
- Versatile Configuration Options: Available in both rising stem and non-rising stem designs to suit different spatial and operational requirements. Connection types can be tailored, including internal (FIP) or external (MIP) threads as per project specifications.
- Wide Pressure & Temperature Range: Engineered to handle common pressure ratings such as PN16 and PN25, with operational temperatures suitable for most marine and industrial hot water or steam services.

Frequently Asked Questions (FAQ):
-
Q: What does "CB/T467" signify for this gate valve?
A: CB/T467 is a Chinese national professional standard specifically for marine valves. It defines the design, material, manufacturing, testing, and inspection requirements to ensure the valve's suitability and safety for shipbuilding and marine applications. -
Q: Is this bronze gate valve suitable for seawater applications?
A: Yes, absolutely. The selected bronze alloys are known for their excellent corrosion resistance against seawater. For prolonged seawater service, specifying a dezincification-resistant bronze grade is recommended. -
Q: What are the main differences between rising stem and non-rising stem designs?
A: A rising stem valve's stem moves up and down with the handwheel rotation, providing clear visual indication of open/closed status but requiring more axial space. A non-rising stem's handwheel rotates in place, suitable for confined spaces, but the position must be indicated by the handwheel orientation. -
Q: Can I get valves with NPT threads instead of BSP threads?
A: Yes, thread types are customizable. While BSP is standard, we can manufacture valves with NPT (National Pipe Tapered) threads upon request. Please specify your required thread standard when inquiring. -
Q: What pressure classes (PN) are available for the DN15-DN50 range?
A> The standard offering is PN16 (16 bar). A higher pressure rating of PN25 (25 bar) is also available. The specific pressure class needed depends on your system's maximum working pressure. -
Q: Do you provide soft-seated versions for zero-leakage applications?
A: Yes. While the standard configuration features a metal-to-metal seat, we offer optional soft seats (e.g., PTFE, reinforced PTFE) that can provide a bubble-tight seal for applications requiring very low leakage rates. -
Q: Are test reports or certifications included with the valves?
A> Yes. As an ISO9001 certified manufacturer, we conduct routine tests (such as shell test, seat test, and material verification). A technical data sheet summarizing these specifications and test results is provided. Detailed test reports can be supplied upon request. -
Q: What is your typical lead time for an order of these valves?
A: Lead time depends on order quantity and specific configurations. For standard DN15-DN50, PN16, BSP threaded valves, we generally maintain stock for common sizes. For customized orders, production time is approximately 30-45 days. We provide a precise schedule upon order confirmation.
