Shanghai Zhibang Valve Manufacture Co., Ltd., an ISO9001-certified manufacturer established in 2016 with an annual export value of US$1–1.5 million, proudly presents the JIS F7305 Pneumatic Globe Valve with Stellite Seating. Designed for demanding high-temperature applications up to 400°C, this DN150, 10K rated valve features welded ends for leak-proof performance and robust construction. Our valves serve clients across North America, Europe, Southeast Asia, and beyond, backed by a professional team and reliable supply chain from Shanghai port.
The JIS F7305 Pneumatic Globe Valve is engineered for precise flow control in industries such as power generation, petrochemical, steam systems, and high-temperature fluid handling. With Stellite alloy seating, the valve delivers exceptional wear resistance and sealing durability even under extreme thermal cycles. The pneumatic actuator allows remote automation, reducing manual intervention and enhancing operational safety.
Key Features
- High-Temperature Capability: Reliable operation at temperatures up to 400°C, suitable for superheated steam and hot oil lines.
- Stellite Seating: Cobalt-based alloy trim resists erosion, corrosion, and galling, providing extended service life.
- Welded Ends: Eliminates potential leakage points, ideal for high-pressure and safety-critical systems.
- JIS Standard Compliance: Manufactured according to JIS F7305 (equivalent to JIS B2071), ensuring interchangeability and quality.
- Pneumatic Actuation: Available in double-acting or spring-return configurations, with positioner options for accurate control.
- Robust Body Construction: Body materials include carbon steel (WCB) and stainless steel (CF8/CF8M) to match various media.
- Compact Design: Optimized flow path reduces pressure drop while maintaining tight shut-off.

Detailed Advantages & Customer Benefits
The Stellite seating is a key differentiator. Unlike standard PTFE or rubber seats, Stellite withstands extreme heat and abrasive particles without deformation, reducing maintenance frequency and valve replacement costs. The welded end design not only simplifies installation in existing piping systems but also eliminates flanged joints common in high-temperature applications where gasket failures are a concern. This makes the valve ideal for steam tracing, boiler feedwater, and superheated steam lines.
The pneumatic actuator can be integrated with a smart positioner for precise throttling or on/off control from a DCS or PLC system. For fail-safe operation, spring-return models close (or open) automatically on loss of air supply, meeting safety requirements. All actuators are tested for quick response and durability.
Customers benefit from our strict quality control throughout manufacturing: from raw material inspection to hydrostatic and pneumatic testing. Every valve is pressure-tested at 1.5 times the rated pressure. We also offer optional nondestructive testing (NDT) like X-ray and dye penetrant upon request.
Typical Applications
- Power plants – main steam, reheat, bypass systems
- Petrochemical refineries – hot oil, high-temperature hydrocarbons
- Chemical processes – thermal fluids, molten salt
- Marine & offshore – steam and condensate lines
- District heating and industrial boilers

FAQ (Frequently Asked Questions)
-
Q: What media can this valve handle?
A: The JIS F7305 Pneumatic Globe Valve is suitable for steam, hot water, thermal oil, gases, and many chemicals. For corrosive media, please specify stainless steel body and trim options. -
Q: Can it be used for oxygen service?
A: Standard Stellite seating is not recommended for oxygen. We can supply specially cleaned and degreased versions with appropriate materials upon request. -
Q: What is the maximum pressure at 400°C?
A: The 10K rating applies to ambient temperature. At 400°C, the allowable working pressure will be reduced according to JIS standards. Please consult our engineering team for the exact pressure-temperature rating of the selected body material. -
Q: Do you provide material certificates?
A: Yes, we provide EN 10204 3.1 or 3.2 material certificates as required. Additional NDT reports (X-ray, PMI, etc.) are available at an extra cost. -
Q: What is the delivery time?
A: Standard valves (common materials and size) typically ship within 30–45 days after order confirmation. Customized valves may take 50–65 days depending on complexity. -
Q: How is the actuator mounted?
A: The actuator is bracket-mounted to the valve bonnet via an ISO 5211 top flange. We can also integrate limit switches, solenoid valves, and positioners for complete automation packages. -
Q: Can the valve be repaired in the field?
A: Yes, the Stellite seat and disk can be reground or replaced. We provide spare parts and maintenance guides. For critical applications, we recommend factory servicing. -
Q: Is the valve suitable for throttling control?
A: Absolutely. With a pneumatic positioner, the globe valve design offers excellent throttling accuracy and stability, making it ideal for modulating control.
