As a professional manufacturer with a solid track record since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance valves for demanding industrial and marine applications. Our CB/T3191 Marine Ball Valve for Fuel Oil is engineered to meet the rigorous requirements of fuel oil transfer and control systems on vessels and offshore installations. With an annual export value demonstrating our global reach and reliability, we deliver valves that combine robust construction, precise operation, and long-term durability, ensuring safe and efficient fluid handling in critical environments.

This specific valve, designed according to the CB/T3191 standard, features a carbon steel body and a hardened seat, making it exceptionally suited for handling fuel oil. The flanged DN50 PN16 configuration provides a reliable and standardized connection for piping systems, offering a balance of strength and flow capacity. We understand the importance of dependable components in marine operations, and this valve is a testament to our commitment to quality and performance.

Key Features and Technical Specifications:

Robust Construction: The carbon steel body offers excellent mechanical strength and resistance to the pressures and environmental conditions encountered in marine service.
Enhanced Sealing: The hardened seat material provides superior wear resistance and a tight seal, minimizing leakage and ensuring reliable shut-off even after prolonged use with fuel oil.
Standardized Connection: The flanged end design (DN50) facilitates easy installation, maintenance, and integration into existing piping networks, complying with common marine piping standards.
Pressure Compatibility: Rated for PN16 pressure, this valve is capable of handling the typical pressure ranges found in fuel oil supply and transfer systems.
Quarter-Turn Operation: The ball valve design allows for quick and easy open/close operation with a simple 90-degree turn, enabling rapid response in control scenarios.
Corrosion Consideration: While carbon steel provides strength, appropriate surface treatments or coatings are available upon request to enhance corrosion resistance for specific environmental conditions.

Frequently Asked Questions (FAQ):

What does "CB/T3191" signify for this valve?
CB/T3191 is a Chinese national standard specifically for marine valves. It outlines the design, material, testing, and performance requirements for valves used in shipbuilding and marine engineering, ensuring they meet the safety and operational needs of maritime applications.
Is this valve suitable only for fuel oil, or can it handle other fluids?
While specifically designed and optimized for fuel oil applications per the standard, the robust carbon steel body and hardened seat may be suitable for other non-corrosive, moderate-pressure fluids. However, compatibility should be verified based on the specific fluid properties.
What are the advantages of a hardened seat in a ball valve?
A hardened seat offers increased resistance to abrasion, wear, and deformation under pressure. This leads to a more durable seal, maintains leak-tight performance over a longer service life, and is particularly beneficial for fluids like fuel oil.
Does the PN16 rating refer to a specific pressure unit?
PN (Pressure Nominal) is a rating system indicating the maximum allowable working pressure at 20°C. PN16 corresponds to a pressure of 16 bar. It's essential to ensure your system's operating pressure is within this rating.
Are other connection types or sizes available for this valve model?
Yes. As a manufacturer, we offer a range of configurations. Other flange sizes (DN values), pressure ratings, or even alternative connection types like threaded ends may be available upon request or as part of our customizable options.
What surface treatments or coatings are offered for corrosion protection?
Standard valves may have a basic protective finish. For enhanced corrosion resistance in harsh marine environments, coatings such as epoxy, galvanization, or other specialized treatments can be applied as an optional feature. Please inquire for specific options.
How does the ISO9001 certification benefit the buyer?
Our ISO9001 certification demonstrates a structured quality management system. It ensures consistent production quality, traceable processes, and continuous improvement, giving buyers confidence in the reliability and repeatability of our products.
What is the typical lead time for ordering this valve?
Lead times depend on order quantity and current stock. With our established manufacturing base and multiple shipment ports, we aim for efficient delivery. Specific lead times can be provided upon quotation request.
