Shanghai Zhibang Valve Manufacture Co., Ltd — a professional manufacturer established in 2016 with ISO9001 certification, exporting valves worldwide including North America, Europe, and Asia. We proudly present our JIS F7305 Pneumatic Globe Valve in 316 Stainless Steel, 10K flanged, DN50, double acting, explosion proof. This valve combines robust design with precise control, ideal for demanding industrial applications requiring safety and reliability. Built with premium materials and stringent quality checks, it ensures long service life and stable performance even in hazardous environments.
Key Features & Benefits
- Material Excellence: 316 stainless steel body and trim offer exceptional corrosion resistance against acids, alkalis, and seawater, making it suitable for chemical, petrochemical, and marine industries.
- Precision Flow Control: Globe valve design provides accurate throttling and shut-off capabilities, with linear flow characteristics for fine-tuning process parameters.
- Double Acting Pneumatic Actuator: Enables fail-safe open/close operation with fast response, requiring air pressure for both directions. Suitable for automation systems and remote control.
- Explosion Proof Construction: Certified explosion-proof actuator (ATEX/IECEx available upon request) ensures safe operation in hazardous areas such as oil & gas, mining, and fuel handling.
- JIS F7305 & 10K Flanged Connection: Conforms to Japanese industrial standard, with 10K pressure rating (approx. 1.0 MPa). Flanged ends allow easy installation and maintenance, compatible with JIS 10K piping systems.
- Compact & Lightweight: Optimized design reduces overall weight while maintaining structural strength, simplifying support requirements and installation costs.
- Durable Sealing: PTFE or reinforced graphite packing ensures zero leakage at stem, with low operating torque for long cycle life.
- Customization Available: Options for positioners, limit switches, solenoid valves, and manual override can be integrated per customer specifications.

Frequently Asked Questions
-
Q: What is the difference between double acting and spring return actuators?
A: Double acting actuators require air pressure to move in both directions, providing constant torque for opening and closing. Spring return (single acting) uses a spring to return to fail-safe position. Double acting is preferred for applications where fail-safe position is not critical and higher torque is needed. -
Q: Can this valve be used for steam service?
A: Yes, the 316 stainless steel body can handle steam up to 180°C with appropriate packing (e.g., graphite). However, for high-temperature steam above 200°C, we recommend consulting our engineers for seat and seal upgrades. -
Q: Is the explosion-proof certification included?
A: The standard valve is designed with explosion-proof housing. Specific certification (ATEX, IECEx, or NEC) can be provided as an option upon request. Please specify your required zone and gas group during order. -
Q: What is the lead time for a standard DN50 valve?
A: Typically 15–25 working days after confirmation, depending on quantity and actuator type. For urgent orders, we can expedite production with prior arrangement. -
Q: Can I add a positioner or limit switch?
A: Absolutely. We can integrate various accessories like 4-20mA positioner, proximity switches, solenoid valves, and manual override. Please provide your control signal requirements. -
Q: How do I install the valve? What flange standard is used?
A: The valve uses JIS 10K RF flanges (raised face). Make sure your pipeline matches JIS 10K standard. Gasket and bolts are typically provided with the valve. Refer to installation manual for torque specifications. -
Q: What is the warranty period?
A: We offer a 12-month warranty from date of shipment against manufacturing defects. Extended warranty and spare parts packages are available. -
Q: Do you provide technical drawings?
A: Yes, dimension drawings, torque charts, and wiring diagrams are supplied upon request. We also provide 3D CAD models for integration into your system.
