As a professional manufacturer of industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-quality, reliable fluid control solutions for demanding maritime environments. Our CB/T467-1995 Bronze Gate Valve with Flanged Connection is engineered specifically for marine and offshore applications, where corrosion resistance, durability, and dependable sealing are paramount. We understand the critical nature of valve performance on vessels and offshore platforms, which is why we adhere strictly to the CB/T467-1995 marine industry standard. With an annual export value reflecting our global reach, we supply robust valves that ensure safe and efficient operation of seawater, ballast, bilge, and fuel oil systems.
This valve is designed to meet the rigorous demands of the shipping industry. Its primary construction from high-grade bronze alloys offers exceptional resistance to saltwater corrosion, a common challenge in marine operations. The flanged connection provides a secure, leak-proof interface that is easy to install and maintain within complex ship piping systems. We focus on delivering products that combine traditional reliability with consistent manufacturing quality, supported by our ISO9001 certified management system.
Core Product Features & Technical Advantages:
- Marine-Grade Bronze Construction: Utilizes tin bronze (C83600, C84400) or leaded bronze alloys known for superior corrosion resistance against seawater, brackish water, and marine atmospheres. This material choice significantly extends service life compared to standard brass or iron valves in salty environments.
- Strict CB/T467-1995 Compliance: Manufactured in full accordance with China's Shipbuilding Industry Standard "Bronze Gate Valves." This ensures dimensional accuracy, material specifications, pressure-temperature ratings, and testing protocols (such as shell test and seat test) are suitable for marine use.
- Robust Flanged Design: Features standard flanged ends (e.g., ANSI B16.5, DIN, JIS, GB) with raised face (RF) or flat face (FF) options. This design ensures a strong, bolted connection that can withstand vibration, pipe stress, and thermal cycling common on ships.
- Bidirectional Sealing Capability: The wedge or parallel slide disc design provides effective sealing in both flow directions, a crucial feature for systems where flow may reverse.
- Low Operating Torque & Smooth Operation: Precision-machined stems and discs, along with proper clearance fits, result in smooth opening and closing action, even after prolonged periods of inactivity. This reduces operator effort and wear on the valve.
- Multiple Actuation Options: Available with standard handwheels, impact handwheels, gear operators for larger sizes, or can be fitted with electric, pneumatic, or hydraulic actuators for remote operation, integrating seamlessly into ship automation systems.
- Enhanced Packing System: Equipped with a deep stuffing box that can accommodate multiple rings of high-quality, asbestos-free packing like graphite or PTFE. An adjustable gland follower allows for easy compression adjustment to maintain a leak-free stem seal.
- Full Bore Design: Typically features a full port (through-conduit) design, minimizing pressure drop across the valve and allowing for easy passage of fluids and potential pigging operations in pipelines.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of using a bronze valve for marine applications instead of cast iron or ductile iron?
A1: Bronze offers far superior corrosion resistance to saltwater and marine atmospheres. Cast iron is highly susceptible to galvanic and pitting corrosion in seawater, leading to rapid degradation. Bronze valves provide a much longer service life and greater reliability in these harsh environments.
Q2: Does compliance with CB/T467-1995 guarantee acceptance by international ship classification societies like ABS, DNV, or LR?
A2: CB/T467-1995 is a respected Chinese marine standard. While it is a strong foundation, final acceptance by a specific classification society (ABS, DNV, LR, BV, etc.) typically requires additional product certification or approval from that society. We can guide you on the approval process and provide necessary documentation.
Q3: Can this valve be used for seawater, ballast, and fuel oil services?
A3: Yes, it is suitable for general seawater, ballast, and non-critical bilge services. For fuel oil (especially heavy fuel oil) or other specific services, the seat and packing material selection may need to be reviewed for compatibility with temperature and fluid properties. Consult with our engineers for specific service recommendations.
Q4: What are the available flange standards and pressure classes?
A4: We commonly manufacture flanges to ANSI B16.5 (Class 150 & 300), DIN EN 1092-1 (PN10/16/25/40), JIS B2220, and GB/T 9113 standards. The specific standard and pressure class (PN/Class) should be specified based on your system design requirements.
Q5: Is the valve suitable for both above-deck and below-deck installations?
A5: Yes, the bronze material performs well in both environments. For below-deck installations in machinery spaces, ensure the selected packing (e.g., graphite) is suitable for the ambient temperature. For above-deck installations exposed to weather, the material's inherent corrosion resistance is a key benefit.
Q6: Do you offer valves with actuators for remote control?
A6: Yes, we can provide the valve prepared for actuator mounting (with a suitable stem and mounting interface) and can supply or recommend compatible electric, pneumatic, or hydraulic actuators based on your control system requirements.
Q7: What is the typical lead time for standard sizes?
A7: For standard sizes and specifications from our catalog, lead times are generally competitive. We ship from major Chinese ports (Shanghai, Guangzhou, etc.). Exact lead times depend on order quantity, specific configuration, and current production schedule. Please inquire for a precise delivery estimate.
Q8: What kind of testing is performed on each valve before shipment?
A8: Every valve undergoes a mandatory hydrostatic shell test (at 1.5x rated pressure) and a seat leakage test (at 1.1x rated pressure) per GB/T 13927 or equivalent standards. Additional tests like material chemical analysis or NDT can be arranged upon request.
