Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium Electric Wafer Butterfly Valve JIS F7481 Design—a compact, high-performance valve engineered for demanding marine and industrial applications. As a dedicated manufacturer since 2016 with an annual export value of US$1-1.5 million, we combine Japanese industrial standards (JIS F7481) with robust ABS construction and NK Approval to deliver reliable flow control under 24V power. This valve is designed to save space, reduce maintenance, and ensure long-lasting performance in environments where safety and compliance are non-negotiable.
Key Features & Technical Specifications
- JIS F7481 Compliant Design – Meets strict Japanese Industrial Standards for marine and industrial butterfly valves, ensuring dimensional interchangeability and reliable performance in shipbuilding and offshore systems.
- 24V DC Electric Actuator – Low voltage (24V DC) operation for safe and energy-efficient control, ideal for battery-backed systems and remote locations. Built-in thermal overload protection and manual override for emergency operation.
- Compact & Lightweight ABS Body – High-strength ABS (Acrylonitrile Butadiene Styrene) material offers excellent corrosion resistance, UV stability, and impact strength. Weighs 50–70% less than metal valves, simplifying installation and reducing structural load.
- NK Approved (Nippon Kaiji Kyokai) – Type-approved by NK (Class NK), verifying suitability for marine applications including ballast water systems, cooling water, and fire-fighting pipelines where classification society acceptance is mandatory.
- Wafer Style with Versatile Mounting – Thin wafer design fits between flanges (PN10/PN16, ANSI 150 optional) with a compact face-to-face dimension per JIS B2002. Can be mounted horizontally, vertically, or at any angle without performance loss.
- Bidirectional Sealing – EPDM or NBR seat liners (customer-specified) provide bubble-tight shut-off in both directions, suitable for potable water, seawater, wastewater, and neutral fluids.
- Easy Maintenance & Extended Service Life – Modular actuator design with quick-connect mounting; self-lubricating stem bearings and corrosion-resistant fasteners ensure long-term reliability with minimal upkeep.

Product Advantages & Customer Benefits
- Space-Saving Compact Design – The wafer configuration and integral actuator reduce overall length, making it ideal for tight installations in ship engine rooms, skid-mounted systems, and machinery spaces.
- Low Power Consumption – 24V DC operation consumes minimal energy (typically
- Corrosion-Free ABS Body – Unlike cast iron or bronze valves, ABS is impervious to galvanic corrosion and saltwater attack, significantly extending service life in marine environments.
- Quick Installation & Commissioning – Pre-assembled actuator with factory-tested performance; simple electrical connection (2-wire or 3-wire control) and flange alignment reduce on-site labor costs.
- Global Maritime Compliance – NK Approval ensures acceptance by major shipyards and classification societies worldwide, facilitating fast project approvals and avoiding costly rework.

Frequently Asked Questions (FAQ)
-
What is the difference between JIS F7481 and standard butterfly valves?
JIS F7481 defines specific face-to-face dimensions, flange drilling, and actuator mounting patterns for Japanese marine applications. This design ensures interchangeability with existing JIS piping systems and is required by many shipbuilders in Asia. -
Can this valve be used with seawater?
Yes. The ABS body and EPDM seat liner are highly resistant to seawater corrosion. NK Approval includes testing in saline environments, making it suitable for ballast water, cooling water, and fire-fighting systems aboard ships and offshore platforms. -
What type of electric actuator is included?
The valve is equipped with a compact, on/off or modulating 24V DC electric actuator with manual handwheel, position indicator, and thermal overload protection. Customizable control options (e.g., 0-10V analogue, Modbus) are available upon request. -
Is NK Approval mandatory for all shipboard installations?
While not compulsory for all vessels, NK (or equivalent class society) approval is typically required for marine equipment on classed ships. Our valve carries NK Type Approval, simplifying regulatory compliance. -
What sizes are available as standard?
We offer DN50 to DN300 (2” to 12”) as standard stock items. Larger sizes up to DN600 can be produced on a project basis with extended lead times. -
How do I install the valve in an existing pipeline?
The wafer design fits between flanges (JIS 10K/16K, PN10/PN16, or ANSI 150). Simply insert the valve, align with flange bolts, and tighten. No additional gaskets are needed if mating flange surfaces are smooth. -
What maintenance is required over the valve’s lifetime?
Minimal maintenance: periodic cleaning of actuator housing, check electrical connections, and lubricate stem (every 6 months in harsh environments). The seat and disc are replaceable; actuator spares are stocked. -
Can I get samples before bulk order?
Yes, we provide pre-production samples for evaluation and type testing. Sample lead time is 7-15 days via express. Please contact our sales team to discuss sample requirements and shipping.
