Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present the JIS F7312 Marine Globe Valve — a full bore, bolted bonnet design engineered for demanding marine and industrial applications. Manufactured in compliance with API 600, this valve delivers reliable shut-off and precise flow control across a wide size range from DN40 to DN200, with a pressure rating of 20K. With over 7 years of manufacturing excellence and annual export value exceeding US$1 million, we ensure every valve meets rigorous quality standards backed by ISO9001 certification.
This globe valve is specifically designed to withstand harsh marine environments, offering robust performance in systems handling seawater, steam, oil, and other fluids. The full bore design minimizes pressure drop and allows for efficient flow, while the bolted bonnet construction provides ease of maintenance and enhanced structural integrity. Whether for shipbuilding, offshore platforms, or industrial pipelines, the JIS F7312 valve is a cost-effective and durable solution.
Key Features & Technical Specifications
- Compliance & Standards: Fully compliant with JIS F7312 and API 600, ensuring international acceptance and interchangeability. Our ISO9001 quality management system guarantees consistent production.
- Pressure Rating: 20K (approximately 3.0 MPa at ambient temperature) suitable for high-pressure marine systems.
- Size Range: DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200 — offering flexibility for various pipeline diameters.
- Full Bore Design: Eliminates flow restrictions, reduces erosion, and minimizes pressure drop compared to reduced bore valves.
- Bolted Bonnet: Allows easy disassembly for inspection, maintenance, and replacement of internal parts without removing the valve from the line.
- Material Options: Body and bonnet available in carbon steel (e.g., WCB) or stainless steel (e.g., CF8M) depending on fluid compatibility. Trim materials such as 13Cr or SS304 are customizable.
- End Connections: Flanged ends per JIS B2212/B2213, with raised face or flat face as required.
- Operation: Manual handwheel operation standard; optional gearbox or pneumatic/electric actuators available upon request.

Frequently Asked Questions
- What is the difference between a globe valve and a gate valve? A globe valve is designed for throttling and flow control, while a gate valve is primarily for on/off service. The JIS F7312 globe valve provides precise regulation with a linear disc movement.
- Can this valve be used for seawater applications? Yes, with stainless steel trim or body material, it is suitable for seawater. We recommend SS316 or duplex stainless steel for corrosion resistance.
- What is the maximum operating temperature for a 20K valve? For carbon steel, typically up to 425°C (797°F), depending on the pressure class. Consult our technical team for exact ratings based on material selection.
- Is the valve supplied with a handwheel or can it be automated? The standard version comes with a handwheel. Optional gearbox, pneumatic, or electric actuators are available upon request.
- Do you provide test certificates and material certificates? Yes, we provide hydrostatic test reports and material certificates as per ISO9001 requirements. Additional third-party inspection is also available.
- What is the lead time for DN150 or DN200 sizes? Standard sizes are usually in stock; for larger sizes, lead time is 2-4 weeks. Please contact us for current availability.
- Can the valve be supplied with non-JIS flanges? Yes, we can customize flanges to ANSI, DIN, or other standards upon request. Please specify your requirement when ordering.
- How do you ensure valve quality before shipment? Every valve undergoes hydrostatic shell test, seat test, and visual inspection. Our ISO9001 quality system covers raw material control, machining, assembly, and testing.
