As a leading manufacturer with a strong foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance fluid control solutions for demanding industrial and marine environments. Our JIS F7301 Marine Ball Valve with Locking Device is engineered to meet the rigorous standards of maritime applications, offering reliable shut-off and control where safety and durability are non-negotiable. With an annual export value reflecting our global reach across markets from North America to Southeast Asia, we understand the critical need for valves that perform consistently under pressure. This valve is designed to provide secure, leak-proof operation in ship piping systems, offshore platforms, and other marine installations, backed by our comprehensive warranty for your peace of mind.
This marine-grade ball valve is constructed to comply with the Japanese Industrial Standard JIS F7301, which specifies requirements for ship valves. The inclusion of a locking device is a crucial safety feature, preventing unauthorized or accidental operation of the valve, which is vital for system isolation during maintenance or in emergency scenarios. Available in sizes from DN15 to DN50, it offers versatile application across various pipeline diameters.
Key Features and Technical Advantages:
- Robust Locking Mechanism: The integrated locking device allows the valve to be secured in either the fully open or fully closed position using a padlock, enhancing operational safety and procedural control.
- Superior Sealing Performance: Features precision-machined ball and seat assemblies, often utilizing materials like PTFE or reinforced polymers, to ensure bubble-tight sealing and long service life even with frequent cycling.
- Corrosion Resistance: Manufactured from materials such as CF8M stainless steel or specially coated carbon steel to withstand harsh marine environments, including saltwater spray and high humidity.
- Low Torque Operation: The design ensures smooth 90-degree operation with minimal effort, whether operated by a lever, wrench, or actuator, reducing wear on components.
- Fire-Safe Design (Optional): Certain models can be configured with fire-safe features where the seat design provides a secondary metal-to-metal seal in case the primary soft seal is compromised by fire.
- Full Port or Standard Port: Options are available to minimize pressure drop (full port) or optimize for space and cost (standard port) based on system requirements.

Frequently Asked Questions (FAQ):
-
Q: What is the primary purpose of the locking device on this ball valve?
A: The locking device serves as a critical safety feature. It allows the valve handle to be secured in a specific position (open or closed) with a padlock, preventing unauthorized or accidental operation. This is essential for isolating systems during maintenance, complying with safety procedures, and ensuring process control on ships and offshore platforms. -
Q: Can this JIS F7301 valve be used in applications other than marine?
A: Absolutely. While designed and certified for marine use, its robust construction, corrosion resistance, and locking feature make it suitable for any industrial application requiring secure fluid isolation, such as in chemical plants, power generation, or water treatment facilities where operational safety is a priority. -
Q: What materials are typically used for the body, and how do I choose?
A: Common body materials include Carbon Steel (WCB) for general service, Stainless Steel (CF8/CF8M) for superior corrosion resistance, and Bronze for seawater applications. The choice depends on the fluid media, temperature, pressure, and environmental conditions (e.g., saltwater exposure). Our team can advise based on your specific service conditions. -
Q: Is the valve suitable for on/off service only, or can it be used for throttling?
A: Ball valves are primarily designed for reliable on/off (isolation) service. While they can be used for throttling in some low-velocity applications, it is generally not recommended as it can cause premature wear of the soft seats and erosion of the ball surface, compromising the seal. For precise flow control, a different valve type like a globe valve is often preferred. -
Q: Are actuators available for this valve, and can they be integrated with the lock?
A: Yes, pneumatic, electric, or hydraulic actuators can be fitted for remote or automated operation. The locking function can often be integrated into the actuator design or provided as an external locking device for the actuator itself, maintaining the safety feature in automated systems. -
Q: What testing is performed on the valves before shipment?
A: Each valve undergoes rigorous testing, which typically includes a shell test (hydrostatic pressure test on the body) and a seat leak test (usually with air or water) to ensure integrity and bubble-tight sealing. Certificates of compliance and test reports can be provided upon request. -
Q: What does the included warranty cover, and for how long?
A: The warranty covers defects in materials and workmanship under normal use and service conditions for a specified period from the date of shipment (e.g., 12-24 months, details provided with the order). It typically does not cover damage from misuse, improper installation, or wear from normal operation. -
Q: Do you offer custom modifications or special coatings?
A: Yes, as a manufacturer, we offer customization. This can include special epoxy or paint coatings for enhanced corrosion protection, specific trim materials, extended stems, different handle types, or modifications to meet other recognized standards like ANSI, DIN, or GB. Please inquire with your specific requirements.
