As a dedicated manufacturer with a strong foothold in the global valve market, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents its high-performance Marine Butterfly Valve DN1000 PN10. Engineered for demanding maritime and offshore applications, this valve combines the robust strength of a ductile iron body with the exceptional corrosion resistance of a 316L stainless steel disc. Designed to ensure reliable flow control in seawater cooling, ballast, firefighting, and other critical shipboard systems, our valve offers superior durability and long service life even in the harshest saline environments. With ISO9001-certified manufacturing processes and extensive export experience to key markets worldwide, we deliver products that meet the stringent requirements of the marine industry.
Core Product Features & Technical Advantages:
- Optimized Material Combination: The ductile iron body provides excellent mechanical strength and pressure resistance, while the 316L stainless steel disc offers superior resistance to pitting and crevice corrosion in chloride-rich environments like seawater.
- Precision Engineering for Tight Shut-off: The disc design and high-quality seat materials (such as EPDM, NBR, or PTFE) ensure bubble-tight sealing, minimizing leakage and ensuring system integrity.
- Low Torque Operation: The streamlined disc design reduces hydrodynamic resistance, allowing for easier operation with manual gearboxes or requiring smaller, more cost-effective actuators.
- Compact & Lightweight Design: Compared to gate valves of similar size, the butterfly valve design offers a significant space and weight saving, which is a critical advantage in ship design and retrofitting projects.
- Versatile Actuation Options: Available with manual gear, electric actuator, or pneumatic actuator to suit different levels of automation and control requirements on board.
- Robust Construction for Longevity: All components are designed and manufactured to withstand vibration, thermal cycling, and the corrosive marine atmosphere, ensuring extended service intervals and reduced maintenance costs.

Frequently Asked Questions (FAQ):
-
Q: Is this valve suitable for full seawater service?
A: Yes, the combination of a ductile iron body (epoxy-coated or other finishes available) and a 316L stainless steel disc makes it highly suitable for seawater, ballast, and other saline water applications. The 316L grade offers enhanced resistance to chloride-induced corrosion. -
Q: What is the standard seat material, and are other options available?
A: The standard seat material is EPDM, which is suitable for a wide range of temperatures and offers good chemical resistance. Alternatives like NBR for oil-based fluids or PTFE for higher temperatures and aggressive chemicals are available as options. -
Q: Can this valve be supplied with an actuator?
A: Absolutely. While manual gear operation is standard, we can provide and pre-assemble electric or pneumatic actuators from reputable brands to meet your automation requirements. Please specify your needs (torque, voltage, signal type) when inquiring. -
Q: What are the flange dimensions and standards for this DN1000 valve?
A: The valve is designed with ISO 5211 flange connections compatible with PN10/16 flanges. Detailed dimensional drawings are available upon request to ensure perfect fitment with your existing piping. -
Q: Is a fire-safe design option available?
A: Fire-safe versions meeting API 607 or similar standards can be offered. This typically involves a metal-seated design or secondary sealing. Please inquire for specific fire-safe requirements. -
Q: What is the lead time for an order of this valve?
A: Lead time depends on order quantity and configuration (e.g., with or without actuator). For standard configurations, typical lead times range from 4-8 weeks. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: Do you provide documentation for classification society approval?
A: We can provide standard material certificates, test reports (like shell test, seat test), and manufacturing data packs. Support for specific classification society (e.g., ABS, DNV, LR) approvals can be discussed based on project requirements. -
Q: How does the manual gearbox operate, and what is the gear ratio?
A: The manual gearbox provides mechanical advantage for easier operation of this large-diameter valve. The specific gear ratio is designed to keep the handwheel operating torque within ergonomic limits. Detailed torque figures and gearbox specifications are provided in our technical datasheet.
