Shanghai Zhibang Valve Manufacture Co., Ltd, established in 2016, is a professional manufacturer specializing in high-quality marine valves. With an annual export value of US$1–1.5 million and serving markets across North America, South America, Europe, Asia, Africa, and Oceania, we bring years of technical expertise and reliable supply chain capabilities. Our JIS F7312 Marine Globe Valve for Ballast Water System is designed to meet the demanding requirements of modern ballast water treatment systems, offering superior flow control, durability, and compliance with international marine standards. As a CCS and BV approved product, this globe valve ensures safety and performance in the most critical marine applications.
The JIS F7312 globe valve is engineered for ballast water systems where precise throttling and shut-off are essential. Constructed from high-grade cast steel (WCB, WCC, or LCB options), it delivers excellent corrosion resistance, high strength, and long service life even in harsh seawater environments. Available in sizes from DN50 to DN250, this valve is suitable for both new builds and retrofitting projects. Below we detail its features, technical specifications, and the direct benefits it brings to your operations.

Why choose our JIS F7312 Marine Globe Valve? The globe valve design inherently offers better throttling capability and tighter shut-off compared to gate valves, making it ideal for ballast water systems where flow regulation is often required. The cast steel body provides robustness against pressure surges and mechanical shocks common in marine environments. Additionally, the availability of both CCS and BV approvals means full compliance with the latest IMO D-2 discharge standards, simplifying vessel certification and port state inspections.
Our factory has been supplying marine valves to shipyards and system integrators worldwide since 2016. We understand the critical nature of ballast water management – a single valve failure can lead to costly delays or non-compliance fines. That is why every valve is individually pressure-tested and seat-tested under witnessed inspection. We also offer tailored solutions such as extended bonnets for insulated piping, special coatings for high-corrosion zones, and custom actuator mounting.
Trust & Credibility: As an ISO9001 certified manufacturer with an annual export value exceeding US$1 million, we maintain strict quality control from raw material sourcing to final packaging. Our main markets include North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and Western Europe – more than 15 countries and regions. We ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports, ensuring efficient logistics. Our JIS F7312 globe valves are already used in numerous ballast water retrofit projects, earning repeat orders from reputable marine engineering firms.

Our engineering team can provide technical drawings, material test certificates, and witness testing arrangements. Choose Shanghai Zhibang Valve for reliable, certified marine globe valves that keep your ballast water system safe and compliant.
Frequently Asked Questions (FAQ)
1. What is the difference between a globe valve and a gate valve for ballast water systems?
A globe valve is designed for throttling and frequent operation, providing better flow control and tighter shut-off than a gate valve. In ballast water systems where precise regulation is needed during treatment cycles, a globe valve is often preferred. Our JIS F7312 globe valve offers excellent linear flow characteristics.
2. Do you offer valves with other regulatory approvals besides CCS and BV?
Yes, we can also supply valves with ABS, DNV, LR, or NK certificates upon request. However, the standard stock for this model holds CCS and BV approvals. Please inquire for specific third-party certification requirements.
3. What is the delivery time for DN50 to DN250 globe valves?
For standard sizes (DN50-DN150) with JIS 10K rating, the lead time is typically 30–45 days. Larger sizes (DN200-DN250) or non-standard pressure classes may require 45–60 days. We can expedite partial orders for urgent projects – contact our sales team for current production schedule.
4. Can these valves be used for seawater service directly?
Yes, the cast steel body with stainless steel trim (SS316 recommended) is suitable for seawater. For long-term corrosion resistance, we can also provide internal epoxy coating (e.g., Fusion Bonded Epoxy) or apply a duplex stainless steel material option. Please specify your service environment when ordering.
5. What testing do you perform before shipment?
Each valve undergoes a hydrostatic shell test at 1.5 times the rated pressure and a seat leakage test at 1.1 times rated pressure, in accordance with JIS B2003. Material certificates, pressure test records, and visual inspection reports are provided with each shipment. Third-party inspection (e.g., CCS surveyor) can be arranged.
6. Do you offer actuator mounting for automated operation?
Absolutely. We can supply the valve with a gearbox, pneumatic actuator, or electric actuator. The mounting interface complies with ISO 5211 standard. We recommend specifying the actuator type (on/off or modulating) and power supply (electric/pneumatic) for optimal integration.
7. What kind of warranty do you provide?
We offer a standard 12-month warranty from the date of shipment against manufacturing defects. Extended warranty up to 24 months is available upon request. Our after-sales team provides technical support and spare parts supply during the warranty period.
8. Can I get a sample valve for testing?
Yes, sample orders are welcome. For stock sizes (e.g., DN50, DN80, DN100), samples can be shipped within 15 days. Sample cost is refundable upon bulk order. Contact us to discuss sample terms and freight arrangements.
