Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer with an annual export value of US$1-1.5 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. Our JIS F7305 10K Globe Valve DN100 PN10 Rising Stem Bolted Bonnet Cast Iron is engineered to deliver reliable performance in demanding industrial applications, combining durable construction with precise flow control. With ISO9001 certification and a global shipping network from Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure consistent quality and timely delivery worldwide.
This globe valve is designed according to the Japanese Industrial Standard (JIS) F7305, offering a pressure rating of 10K (equivalent to PN10) and a nominal diameter of DN100. The rising stem provides a clear visual indication of the valve position, while the bolted bonnet design facilitates easy maintenance and disassembly. Crafted from high-quality cast iron, this valve offers excellent corrosion resistance and durability, making it suitable for water, oil, and gas applications in general-purpose piping systems.
Key Features & Technical Specifications
- Material: High-grade cast iron body and bonnet, ensuring long-term strength and resistance to thermal and mechanical stress.
- Rising Stem: Indicates open/close status at a glance; stem material is brass or stainless steel (optional upon request).
- Bolted Bonnet: Allows quick access to internal parts for inspection, cleaning, or repair, reducing downtime.
- Disk & Seat: Machined to provide tight shut-off, minimizing leakage and improving control accuracy.
- Flanged Ends: Conform to JIS B2210 or B2220 (10K) drilling pattern; face-to-face dimensions per JIS B2002.
- Pressure Rating: 10K (max. 1.0 MPa at 120°C for cast iron; higher temperatures may reduce rating—consult technical data).
- Operation: Handwheel-operated, customizable with chain wheel, gear actuator, or electric actuator (available upon request).
- Testing: 100% hydrostatic shell test and seat leakage test per JIS B2001 or equivalent standard.

Frequently Asked Questions
-
Q: What are the main applications of the JIS F7305 10K Globe Valve?
A: It is commonly used in water supply systems, irrigation, HVAC, oil and gas pipelines (non-corrosive media), and general industrial fluid handling where moderate pressure and temperature conditions exist. -
Q: Can this valve be used for throttling (flow regulation)?
A: Yes, globe valves are designed for throttling and regulation. The rising stem provides visual feedback, and the disk/seat design allows fine flow adjustment. However, for continuous throttling at high differential pressures, alternative trim materials may be recommended—please consult us. -
Q: What is the difference between 10K and PN10? Are they exactly the same?
A: JIS 10K and PN10 (ISO 7268) are very similar but not identical. 10K has a pressure rating of about 1.0 MPa at ambient temperature, matching PN10 in many cases. However, flange dimensions may differ. Our valve is designed to JIS F7305 and tested to 10K, but it can also be used in PN10 systems with appropriate flanges—please verify compatibility with your piping standard. -
Q: Is the valve suitable for steam service?
A: Cast iron valves have limitations for steam due to thermal shock and lower strength at elevated temperatures. For saturated steam up to 120°C and low pressure, this valve may be used, but we recommend checking the specific operating conditions with our technical team. For higher temperature steam, consider ductile iron or steel valves. -
Q: What certifications does your company hold for this product?
A: Our company is ISO9001 certified, ensuring a quality management system for design, production, and testing. The valve itself is manufactured according to JIS F7305. Specific third-party certifications (e.g., CE, UL) are not included unless specially requested and may incur additional cost and lead time. -
Q: Can I get the valve with a different actuator or stem material?
A: Yes, we offer options such as electric, pneumatic, or gear actuators, as well as stainless steel stem, bronze disk, or other trim combinations. Please inform us of your requirement when placing an order. -
Q: What is the typical lead time for this product?
A: For standard DN100 cast iron globe valves, lead time is approximately 15-30 days after order confirmation, depending on quantity and current production load. We also maintain stock of popular sizes for quick shipment. Contact our sales team for real-time stock and lead time update. -
Q: How do I ensure the valve is properly installed?
A: Install the valve with the flow direction arrow (usually marked on the body) matching the pipeline flow. Use proper gaskets and bolts according to JIS flange standards. Do not overtighten the handwheel during installation. For detailed instructions, refer to our installation and maintenance manual provided with each order.
