Shanghai Zhibang Valve Manufacture Co., Ltd, a professional manufacturer established in 2016 with an annual export value of US$1-1.5 million and ISO9001 certification, proudly presents the JIS F7312 Cast Steel Marine Globe Valve. Designed specifically for high-temperature steam applications, this flanged globe valve covers sizes from DN25 to DN150 and is available in 10K and 16K pressure ratings. Built with durable cast steel and precision engineering, it ensures reliable throttling and shut-off in marine and industrial steam systems. Our commitment to quality and global market reach—shipping to North America, Europe, Asia, Africa, and more—makes this valve a trusted choice for demanding environments.
The JIS F7312 globe valve is manufactured to strict Japanese Industrial Standards, guaranteeing interchangeability and compliance with international marine requirements. Its robust cast steel body withstands high thermal stress, while the flanged connections provide leak-proof sealing and easy installation. Whether used in boiler systems, steam pipelines, or shipboard utilities, this valve delivers long service life with minimal maintenance.
Key Features & Benefits
- High Temperature Resistance: The cast steel material and special seat design allow continuous operation with saturated or superheated steam up to 425°C.
- JIS F7312 Compliance: Full adherence to Japanese Industrial Standard ensures dimensional consistency and interchangeability with other JIS components.
- Flanged Ends (DN25-DN150): Raised face flanges suitable for 10K and 16K pressure classes, compatible with standard pipe flanges.
- Smooth Flow Control: Globe valve disk and seat provide precise throttling and positive shut-off, reducing pressure drop and erosion.
- Durable Cast Steel Body: Single-piece cast carbon steel (ASTM A216 WCB or equivalent) offers excellent mechanical strength and corrosion resistance in steam service.
- Wide Application: Ideal for marine main and auxiliary steam systems, power plants, and industrial steam distribution networks.
- ISO9001 Certified Manufacturing: Each valve undergoes rigorous inspection and testing to ensure leak-tightness and operational safety.
- Customizable Options: Available with handwheel, gear operator, or pneumatic/electric actuator upon request; color coating can be customized.

Each valve is hydrostatically tested at 1.5 times the rated pressure to verify body and seat integrity. The cast steel construction provides excellent thermal conductivity, while the hardened stainless steel seat ring offers superior wear resistance even under frequent cycling. Compared to gate or ball valves, the globe valve design gives finer flow control and is less susceptible to wire drawing in high-velocity steam applications.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum working pressure for the 10K and 16K versions?
A: The 10K rating corresponds to approximately 1.0 MPa (145 psi) at ambient temperature, while 16K corresponds to 1.6 MPa (232 psi). For steam service at elevated temperatures, derating factors apply; please consult our technical data sheet for specific values. -
Q: Can this valve be used for superheated steam above 425°C?
A: The standard valve is designed for steam up to 425°C. For higher temperatures, we recommend upgrading to alloy steel or stainless steel materials. Contact our engineering team for a customized solution. -
Q: Are the flanges compatible with ANSI or DIN standards?
A: The flanges are manufactured per JIS B2220 for 10K/16K. They differ from ANSI class 150/300 in bolt hole pattern and face dimensions. If ANSI flanges are required, we can provide adapters or custom flanges upon request. -
Q: What is the typical lead time for an order?
A: For standard sizes (DN25-DN100) with handwheel operation, lead time is 15-25 working days. Larger sizes or actuators may require 30-40 working days. We maintain stock for popular sizes—please inquire. -
Q: Is the valve supplied with a handwheel or can it be automated?
A: The standard configuration includes a cast iron handwheel. For remote operation, we offer pneumatic diaphragm actuators, electric actuators, or bevel gear operators. Mounting brackets and accessories are available. -
Q: How do you ensure the valve is leak-free during installation?
A: Each valve is hydrostatically tested at 1.5x rating before shipping. We also recommend using the correct gasket material (e.g., spiral wound for steam) and tightening bolts evenly to the torque specified in our installation manual. -
Q: What kind of maintenance does this globe valve require?
A: Periodic inspection of the packing gland, seat condition, and stem threads is recommended. The valve is designed for easy disassembly; replacement parts (gaskets, packing, seat rings) are available from our warehouse. -
Q: Do you provide a material certificate or third-party inspection?
A: Yes, we can issue material test certificates (MTC) per EN 10204 3.1 or other standards at extra cost. Third-party inspections by SGS, BV, or Lloyds are also available upon request.
