The core value of this gate valve lies in its ability to provide a secure, leak-resistant seal under high-pressure conditions, ensuring operational safety and efficiency. Its design caters to industries where fluid flow management is critical, offering a solution that balances strength, compliance with international standards, and cost-effectiveness. With an annual export value reflecting our global reach, we supply these valves to key markets worldwide, backed by our ISO9001-certified manufacturing processes for consistent quality.
Key Features & Technical Specifications:
- Ductile Iron Construction: Provides superior strength, impact resistance, and durability compared to standard cast iron, suitable for high-stress environments.
- JIS F7363 Compliance: Manufactured according to Japanese Industrial Standards, ensuring precise dimensions, material quality, and performance benchmarks for gate valves.
- Pressure Ratings: Available in both 5K (approx. 5 kgf/cm²) and 10K (approx. 10 kgf/cm²) pressure classes, catering to medium and higher-pressure system requirements.
- Size Range Flexibility: Offered in a comprehensive range from DN50 (2") to DN300 (12"), allowing integration into various pipeline diameters.
- Flanged Ends: Standard design features flanged connections for secure bolting to piping systems, facilitating installation and maintenance.
- Manual Operation: Typically equipped with a handwheel for straightforward open/close control, suitable for applications where automated actuation is not required.
- Sealing Mechanism: Utilizes a metal gate and seat for primary sealing. Optional resilient seating materials are available upon request for specific fluid compatibility.
- Broad Temperature Tolerance: Designed to operate effectively in temperatures up to 120°C. Higher temperature ratings can be customized based on project needs.

Frequently Asked Questions (FAQ):
-
Q: What does the "5K" and "10K" pressure rating signify for this valve?
A: "K" refers to the Japanese pressure class (kgf/cm²). 5K corresponds to a nominal pressure rating of approximately 5 kgf/cm² (about 0.5 MPa or 70 psi), while 10K corresponds to approximately 10 kgf/cm² (about 1 MPa or 140 psi). It indicates the maximum pressure the valve is designed to withstand under normal operating conditions. -
Q: Is this valve suitable for steam applications?
A: The standard valve is designed for temperatures up to 120°C. For steam service at higher temperatures and pressures, specific material and design modifications may be required. Please consult with our technical team for customized solutions for steam applications. -
Q: Can this valve be equipped with an actuator for automated operation?
A: The standard version is manual. However, the design can typically accommodate the mounting of an electric, pneumatic, or hydraulic actuator. Actuator attachment kits or customized valves with actuators are available upon request. -
Q: Does the valve come with specific sealing materials, or are options available?
A: The standard sealing is metal-to-metal (gate and seat). For applications requiring better sealing with different fluids or to reduce wear, optional resilient seating materials (such as certain elastomers) can be provided. Material selection depends on fluid compatibility and operating conditions. -
Q: How does JIS F7363 compare to other common valve standards like ANSI or DIN?
A: JIS F7363 is a Japanese standard specifying requirements for iron gate valves. It defines dimensions, materials, testing, and markings. While it has similarities to other standards, it is a distinct specification. It is widely accepted in projects specifying JIS compliance, particularly in Asia and internationally where Japanese standards are referenced. -
Q: What is the typical lead time for orders of these valves?
A: Lead times vary based on order quantity, specific size/pressure rating, and customization. For standard sizes and ratings from our inventory, shipment can be arranged promptly. For large or customized orders, production time will be provided upon quotation. Our multiple shipment ports enable flexible logistics. -
Q: Are testing and inspection reports provided with the valves?
A: As an ISO9001-certified manufacturer, we conduct quality inspections during production. Standard inspection reports can be provided. Specific testing protocols (like pressure testing reports) are available upon request. -
Q: What maintenance is recommended for this gate valve?
A: Routine maintenance includes periodic operational checks for smooth opening/closing, inspection of external surfaces, and ensuring flange bolts are secure. For the internal sealing components, maintenance intervals depend on operating cycles and fluid characteristics. The robust ductile iron construction generally requires minimal maintenance under normal conditions.
