As a dedicated manufacturer with a strong foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in producing high-performance valves for demanding industrial and marine applications. Our DN50 PN6.4MPa Marine Ball Valve with Mounting Pad is engineered to meet the rigorous standards of marine environments, offering reliable shut-off and control in piping systems. Built in compliance with CB/T3191 and constructed from durable cast steel, this valve represents our commitment to delivering robust, long-lasting solutions that ensure operational safety and efficiency for our clients worldwide.

This valve is designed to address the specific needs of marine engineering, where equipment must withstand corrosive conditions, high pressures, and constant use. The inclusion of a mounting pad provides enhanced stability and simplifies installation, making it a preferred choice for shipbuilders, offshore platform operators, and port facility managers. With our ISO9001 certified manufacturing processes, we guarantee consistent quality and performance, backed by an annual export value reflecting our global reach across markets from North America to Southeast Asia.

Key Features & Technical Specifications:

Robust Construction: The valve body and key components are made from high-grade cast steel, providing excellent resistance to corrosion, impact, and high-pressure stresses common in marine settings.
Precision Ball Design: The spherical closure element ensures a tight seal with minimal torque, allowing for quick and easy operation. The sealing surfaces are often treated or paired with resilient materials like PTFE for low leakage rates.
Mounting Pad Integration: The integrated mounting pad offers a secure attachment point, facilitating easier alignment and fixation within complex piping layouts or support structures, reducing installation time and potential errors.
High Pressure Capability: Rated at PN6.4MPa, this valve is suitable for systems requiring substantial pressure containment, such as fuel lines, cooling water circuits, and hydraulic systems on vessels.
Standard Compliance: Adherence to the CB/T3191 standard ensures the valve meets specific dimensional, material, and performance criteria recognized within the marine industry, promoting interoperability and safety.
Versatile End Connections: While typically designed for flanged connections (which can be specified), threaded ends or other connection types are available upon request to suit different piping standards.
Operational Flexibility: The valve can be operated manually via a lever or handwheel. Options for pneumatic, hydraulic, or electric actuation are customizable for automated control systems.

Frequently Asked Questions (FAQ)

Q: What is the primary advantage of the mounting pad on this ball valve?
A: The mounting pad provides a dedicated, sturdy point for securing the valve to a support structure or frame. This enhances stability, reduces stress on the pipeline connections, and simplifies the installation process, which is particularly valuable in space-constrained or vibration-prone marine environments.
Q: Does compliance with CB/T3191 mean the valve is only for Chinese marine projects?
A: No. While CB/T3191 is a Chinese standard for marine valves, it specifies rigorous requirements for dimensions, materials, and performance that are respected internationally. Many global shipbuilders and operators accept or require valves meeting such recognized national standards, ensuring quality and compatibility.
Q: Can this valve be used with fluids other than water, such as oil or gas?
A: Yes, provided the seal material is appropriate. With standard PTFE seals, it is suitable for a wide range of media including water, oil, air, and many inert gases. For aggressive chemicals or specific gases, alternative seal materials can be selected upon request.
Q: Is the valve suitable for high-temperature applications beyond 200°C?
A: The standard temperature range is typically -20°C to +200°C based on common seal materials. For higher temperature services, special seal and material options can be explored. Please consult with our technical team for specific high-temperature requirements.
Q: What types of actuation are available if I need automated operation?
A: We can provide valves prepared for attachment of pneumatic (air), hydraulic (oil), or electric actuators. The valve can be supplied with a standardized interface (like a ISO mounting pad) for actuator connection. The specific actuator type and control signal would be customized based on your system design.
Q: How does the cast steel construction compare to stainless steel for marine use?
A: Cast steel offers high strength and good corrosion resistance, often at a lower cost than stainless steel. For many marine applications involving seawater, cast steel with proper surface treatment or coating is sufficiently durable. Stainless steel options are available for more corrosive environments or specific client preferences.
Q: What is the typical lead time for ordering this valve?
A: For standard configurations, lead times are generally competitive due to our established manufacturing流程. Customized orders (specific actuation, connections, seals) may require additional time. We provide accurate lead time estimates upon order confirmation.
Q: Are testing and inspection reports provided with the valve?
A: Yes, as an ISO9001 certified manufacturer, we conduct routine inspections and tests (such as pressure tests, material checks). Relevant documentation can be provided upon request to support quality assurance protocols.
