Shanghai Zhibang Valve Manufacture Co.,ltd, established in 2016 with an annual export value of US$1 million to US$1.5 million, proudly presents the JIS F7312 10K Cast Steel Globe Valve with Gearbox, DN100. This valve is engineered for precise flow control in demanding industrial applications, offering reliable shut-off and throttling capabilities. Our factory, certified with ISO9001, ensures consistent quality and strict adherence to JIS standards, making this globe valve a trusted choice for global markets including North America, Europe, Southeast Asia, and the Middle East.
The valve features a robust cast steel WCB body, a threaded bonnet design for easy maintenance, and a gearbox operator that provides smooth, high-torque actuation even under high pressure. The flanged connection (10K rating) matches standard JIS pipe flanges, ensuring leak-free installation. Whether you need isolation or regulation, this globe valve delivers exceptional performance across water, oil, and gas systems.
Key Features & Benefits
- Material Excellence: Cast steel WCB (ASTM A216 WCB) provides high strength, good corrosion resistance, and suitability for moderate-temperature applications up to 425°C (approximately).
- Pressure Rating 10K: Designed to withstand the 10K pressure class (approx. 1.0 MPa, 150 psi) as per JIS B2201, ensuring safety and durability in medium-pressure systems.
- Threaded Bonnet Construction: Offers a reliable seal and simplifies maintenance – bonnet can be easily removed for seat and disc inspection without disturbing the pipeline.
- Gearbox Operation: Reduces operating torque, allowing smooth manual actuation even under high differential pressure. Ideal for large-diameter valves (DN100) where handwheel effort would be excessive.
- Flanged Connection: Standard JIS 10K flanges (RF or FF face) ensure compatibility with existing piping systems. Easy installation and zero-leak performance with proper gaskets.
- Full Port Design: The globe valve offers straight-through flow path with low pressure drop when fully open, and excellent throttling characteristics when partially open.
- Stellite Seating (Optional): For demanding services, hardfaced seat and disc can be supplied to resist erosion and extend service life.
- Certified Quality: Our factory operates under ISO9001 quality management system. Each valve undergoes hydrostatic shell and seat tests as per JIS B2003 or API 598.
