As a professional manufacturer with a strong export presence since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding marine environments. Our Manual Marine Butterfly Valve with a Standard-Compliant Lever Handle is engineered to deliver dependable performance, ease of operation, and long-term durability in critical shipboard and offshore applications. With technical support readily available, we ensure seamless integration and optimal functionality for your specific system requirements.

This valve is designed for precise flow regulation and isolation in seawater cooling systems, ballast systems, fuel lines, and general service pipelines on vessels and marine structures. Its straightforward manual operation, combined with robust construction, makes it a preferred choice for engineers seeking a balance of performance, cost-effectiveness, and maintenance simplicity.

Key Product Features & Technical Advantages:

Robust Construction for Marine Duty: Manufactured from high-grade materials resistant to corrosion from saltwater, chemicals, and harsh marine atmospheres. Common body/disc materials include cast iron with epoxy coating, ductile iron, and stainless steel (304/316).
Standard-Compliant Lever Handle: The ergonomically designed lever handle provides clear, visual indication of valve position (open/closed) and allows for quick, quarter-turn operation with minimal effort, enhancing operational safety and efficiency.
Superior Sealing Performance: Features a resilient seat (options like EPDM, NBR, or PTFE) that ensures a bubble-tight seal, preventing leakage and ensuring system integrity even under variable pressure conditions.
Versatile Connection Options: Available in both Lug and Wafer styles to suit different piping system designs and installation requirements, facilitating easy integration without extensive modification.
Customizable Specifications: We understand that marine projects have unique needs. Key parameters such as pressure rating (PN10, PN16, etc.), size range, and material combinations can be tailored to match your specific technical datasheet.

Frequently Asked Questions (FAQ)

Q: What makes this a "marine-grade" butterfly valve?
A: Marine-grade valves use materials and coatings specifically chosen to resist saltwater corrosion, biofouling, and harsh weather conditions typical of maritime environments, unlike standard industrial valves.
Q: Can the lever handle be locked in position?
A: Yes, the standard lever handle often includes provisions for padlocking in the fully open or closed positions, a common requirement for safety and procedure compliance onboard ships.
Q: What is the difference between Lug and Wafer type connections?
A: Lug-type valves have threaded inserts (lugs) for bolt connections on both sides, allowing valve removal without disturbing the entire pipeline. Wafer-type valves are sandwiched between two pipeline flanges and are generally lighter and more compact.
Q: How do I select the appropriate seat material (EPDM, NBR, PTFE)?
A: Selection depends on the fluid media and temperature. EPDM is suitable for hot water and mild chemicals; NBR is for oils and fuels; PTFE offers excellent chemical resistance and a wider temperature range. Our technical team can advise based on your application.
Q: Is this valve suitable for seawater service?
A: Yes, with the correct material specification (e.g., Stainless Steel 316 body/disc and EPDM or Viton seat), this valve is well-suited for seawater cooling, ballast, and firefighting systems.
Q: What is included in your "technical support available" service?
A: Our support includes assistance with valve selection, sizing, material compatibility checks, installation guidance, and troubleshooting. We provide datasheets, CAD drawings, and direct engineer consultation.
Q: Do you provide certifications or test reports for the valves?
A: As an ISO9001-certified manufacturer, we can provide standard material certificates and factory test reports (like shell test, seat test) upon request. Specific marine class certifications may be available as a custom option.
Q: What is your typical lead time for custom orders?
A: Lead times vary based on order quantity and customization level. Generally, for standard configurations, production can be completed within 15-30 days, with shipping arranged promptly from our major ports.
