As a professional valve manufacturer based in Shanghai, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance fluid control solutions for demanding marine and industrial applications. Established in 2016, we have built a solid reputation in the global market, exporting to over a dozen regions worldwide. Our JIS F7481 5K Marine Wafer Butterfly Valve DN300 with Lever Operation and EPDM Seal is engineered to meet the rigorous standards of shipbuilding and offshore operations. This valve offers a reliable, compact, and cost-effective solution for on/off and throttling services in seawater, ballast, cooling, and other shipboard piping systems.
This valve is designed for durability and ease of operation in the challenging marine environment. Its robust construction ensures long service life with minimal maintenance, a critical factor for vessel operators. The lever operation provides quick and visual indication of the valve position, enhancing operational safety and efficiency onboard.
Key Features & Technical Advantages:
- JIS F7481 5K Standard Compliance: Manufactured strictly in accordance with the Japanese Industrial Standard (JIS) F7481 for marine valves with a pressure rating of 5K (approximately PN10). This ensures compatibility and reliability in international shipbuilding projects.
- Compact Wafer Design: The wafer-style body installs conveniently between two pipe flanges, significantly saving space and weight compared to lug-type or flanged valves—a crucial advantage in space-constrained engine rooms and piping systems.
- High-Performance EPDM Seal: The valve utilizes an Ethylene Propylene Diene Monomer (EPDM) elastomer seat, which provides excellent resistance to seawater, mild chemicals, and a wide temperature range from -15°C to 120°C, ensuring a tight, bubble-tight shut-off.
- Robust Lever Operation: The simple yet sturdy lever handle allows for quick 90-degree rotation, enabling fast opening and closing. The lever position clearly indicates whether the valve is open or closed, preventing operational errors.
- Durable Construction: The valve body and disc are typically crafted from high-quality cast iron or ductile iron, offering superior strength and corrosion resistance. The stem is made from stainless steel to prevent seizure and ensure smooth operation.
- Versatile Marine Application: Ideally suited for a variety of shipboard services including ballast systems, seawater cooling lines, firefighting systems, tank venting, and general service lines on tankers, cargo ships, offshore platforms, and fishing vessels.

Frequently Asked Questions (FAQ)
-
What does "5K" pressure rating mean in JIS standard?
In JIS F7481, "K" stands for "Kogata" and indicates the pressure rating. 5K corresponds to a nominal pressure of approximately 0.5 MPa (5 kgf/cm²), which is roughly equivalent to PN10 in European standards. It is suitable for low to medium-pressure applications common in marine systems. -
Can this wafer butterfly valve be used for throttling flow control?
While primarily designed for on/off service, the lever-operated butterfly valve can be used for basic throttling by positioning the lever at intermediate angles. However, for precise flow control, especially in continuous throttling applications, a gear-operated valve might be recommended. -
Is the EPDM seal suitable for oil or fuel lines?
EPDM has good resistance to water, steam, and many chemicals but is generally not recommended for hydrocarbon-based fluids like oil and fuels. For such services, alternative seat materials like NBR (Nitrile) or Viton® can be offered as options. -
What is the main advantage of a wafer-type valve over a lug-type?
The wafer type is lighter, more compact, and typically more cost-effective. It is installed by bolting between two pipeline flanges, with the flange bolts carrying the pipeline load. Lug-type valves have threaded inserts (lugs) and can be installed at the end of a pipeline, but they are heavier and bulkier. -
Do you provide certificates for the material and pressure testing?
Yes, as an ISO9001 certified manufacturer, we can provide standard material certificates (CMTR) and hydrostatic test reports for the valves upon request. These documents are often required for marine classification society approvals. -
Can the lever handle be locked in position?
The standard lever handle does not include a built-in locking mechanism. However, padlockable lever locks or locking devices can be supplied as optional accessories to secure the valve in the open or closed position for safety or procedural reasons. -
What are the available alternatives for the valve body material?
While cast iron/ductile iron is standard for JIS 5K valves, we can also supply valves in other materials like cast steel (SCPH2) or stainless steel (CF8M) for more corrosive environments or specific client specifications. These would be custom options. -
What is the typical delivery lead time for an order of DN300 valves?
Lead times vary based on order quantity and current production schedule. For standard DN300 JIS F7481 5K valves with lever operation, typical lead times range from 4 to see 8 weeks. We recommend contacting our sales team for an accurate delivery schedule based on your project timeline.
