With an annual export value of US$1-1.5 Million and a strong presence in markets from North America to Southeast Asia, our products are trusted by clients worldwide for critical offshore and marine operations. This valve is engineered to deliver exceptional shut-off performance under high-pressure conditions, ensuring the integrity and safety of your fluid handling systems.
Our Cast Steel JIS F7363 Gate Valve is built to withstand the corrosive and high-pressure challenges of marine service. Below are the key features and technical specifications that set this product apart:
- Robust Construction: Manufactured from high-quality cast steel, providing superior strength and resistance to corrosion, essential for long-term operation in seawater and harsh offshore environments.
- JIS F7363 Compliance: Strictly adheres to the Japanese Industrial Standards for steel castings for valves, ensuring dimensional accuracy, material integrity, and performance reliability recognized in international marine projects.
- High-Pressure Capability: With a 10K pressure rating, it is suitable for a wide range of high-pressure fluid control applications on FPSOs, including crude oil, seawater, and ballast systems.
- Full Port Design: Minimizes pressure drop and allows for efficient pigging or inspection tool passage, which is crucial for pipeline maintenance in FPSO operations.
- Rising Stem Design: Provides a clear visual indication of the valve position (open or closed), enhancing operational safety and preventing accidental mishandling.
- Premium Sealing: Utilizes stainless steel seat rings and high-quality graphite packing to ensure a bubble-tight seal, preventing leaks even after prolonged use and thermal cycling.
- Versatile Size Range: Available in sizes from DN50 to DN200, offering flexibility for various pipeline configurations and flow capacity requirements on marine vessels and platforms.
- Easy Operation and Maintenance: Features a handwheel operation for manual control. The design allows for easy in-line maintenance, reducing downtime and operational costs.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of using a JIS F7363 standard valve on an FPSO?
A: The JIS F7363 standard specifies requirements for steel castings used in valves, ensuring high material integrity, dimensional precision, and performance consistency. For FPSOs, this translates to enhanced reliability and safety in critical, corrosive offshore environments, and it is widely recognized and accepted in international marine projects, particularly in the Asian market.
Q2: Can this valve handle crude oil and seawater applications?
A: Yes, absolutely. The cast steel body provides excellent corrosion resistance, and the stainless steel trim (seat and stem) is suitable for both crude oil and seawater services. The specific material grade can be confirmed based on your fluid composition and temperature requirements.
Q3: Is the 10K pressure rating sufficient for high-pressure FPSO systems?
A: The 10K rating (approximately equivalent to PN16 or Class 150) is a common and suitable rating for many fluid transfer and isolation applications on FPSOs, including various process, utility, and ballast systems. For higher pressure requirements, alternative pressure classes can be explored as a customizable option.
Q4: Are these valves available with actuators for remote operation?
A: While the standard configuration is handwheel-operated, our valves are designed to be compatible with various pneumatic, hydraulic, or electric actuators. Actuator mounting kits and automated solutions are available upon request to suit your control system needs.
Q5: What is the typical lead time for an order of DN150 valves?
A: Lead times vary based on order quantity and specific configuration. Generally, for standard DN150 valves, we maintain a competitive lead time. Please contact our sales team with your required quantity for an accurate delivery schedule. We ship from multiple ports for flexibility.
Q6: Do you provide documentation like material test certificates?
A> Yes, as an ISO9001 certified manufacturer, we can provide necessary documentation, including material test certificates (MTC), inspection reports, and packing lists, to support your quality assurance and import procedures.
Q7: What maintenance does this gate valve require?
A: These valves are designed for low maintenance. Periodic checks of the gland packing for tightness and lubrication of the stem threads are recommended. The robust design allows for in-line servicing of seats and packing if needed, minimizing downtime.
Q8: Are other end connections besides JIS flanges available?
A: The standard offering features JIS flanges. However, we understand that projects may require different standards like ANSI, DIN, or GB. Other flange standards or connection types can be considered as a custom modification subject to feasibility and order volume.
