As a professional manufacturer of industrial valves with ISO9001 certification and a strong presence in global markets, Shanghai Zhibang Valve is proud to offer this high-performance Stainless Steel Marine Ball Valve. Engineered specifically for the demanding environments of marine and offshore applications, this DN80 PN40 valve combines robust construction with the approvals of leading maritime classification societies. It is designed to provide reliable, long-lasting service in critical fluid control systems on ships, platforms, and coastal facilities.
This valve is built to withstand the corrosive effects of seawater, harsh weather, and demanding operational cycles. Its core value lies in delivering uncompromised safety and durability where failure is not an option. We understand the critical nature of marine operations, and our valve is manufactured to meet the stringent standards required by shipbuilders, ship owners, and offshore operators worldwide.
Key Product Features & Technical Specifications:
- Superior Corrosion Resistance: Constructed from high-grade stainless steel (typically 304 or 316), offering excellent resistance to saltwater corrosion, pitting, and crevice corrosion, ensuring a long service life in marine atmospheres.
- High-Pressure Integrity: Rated for PN40 pressure (equivalent to Class 150/300), making it suitable for a wide range of shipboard systems including ballast, bilge, cooling water, fuel oil, and general service lines.
- Full Bore Design: Provides minimal flow restriction and pressure drop, allowing for efficient fluid transfer and easier pigging or cleaning of the pipeline.
- Robust Sealing System: Features seats made from advanced polymers like PTFE or reinforced PTFE, which ensure bubble-tight shut-off, low operating torque, and reliable performance across the specified temperature range.
- Durable Stem & Blow-out Proof Design: The stem is integrated with an anti-blowout feature, preventing ejection under pressure, and is sealed with multiple packing rings to prevent external leakage.
- Fire-Safe Design Option: Available with fire-safe features in accordance with API 607/6FA standards, where secondary metal sealing provides containment in case of a fire, a critical safety feature for fuel lines.
- Versatile End Connections: Standard configuration is flanged (e.g., ANSI B16.5, DIN, JIS, GB standards), ensuring easy integration into existing international piping systems. Other end types like butt-weld or threaded are available upon request.

Frequently Asked Questions (FAQ):
-
Q: What specific CCS, DNV, and LR approval certificates does this valve hold?
A: This valve is manufactured, tested, and documented according to the rules and standards of these classification societies. It typically holds type approval or is produced under their survey for materials, design, and pressure testing. Specific certificate numbers and scopes can be provided upon request for your project documentation. -
Q: Is the valve suitable for seawater service?
A: Yes, absolutely. The use of 316 stainless steel, which has higher molybdenum content for enhanced pitting resistance, is highly recommended for direct seawater service. We can advise on the optimal material grade based on your specific fluid and operating conditions. -
Q: Can this valve be supplied with pneumatic or electric actuators?
A: Yes. The valve is designed with a standardized mounting pad according to ISO 5211, making it compatible with a wide range of quarter-turn pneumatic, electric, or hydraulic actuators from various brands. We can supply the valve as a manual unit or as a complete actuated package. -
Q: What is the lead time for an order of 50 pieces of this DN80 valve?
A: For standard configurations with CCS/DNV/LR approval, our typical production lead time is 4-6 weeks. This can vary based on current order volume and specific customization requirements. We provide accurate lead time estimates with every formal quotation. -
Q: Do you provide test reports and certification with the valves?
A: Yes. Each batch of valves undergoes rigorous testing including hydrostatic shell test, seat leak test, and operational torque check. We provide a comprehensive test report and material certificates (MTC) as standard. Classification society surveyor attendance during testing can be arranged if required. -
Q: What packaging is used for export shipment to prevent damage during sea transit?
A: Valves are carefully cleaned, dried, and preserved. They are then packaged in individual plastic bags or wrapped with VCI paper to prevent corrosion. For flanged valves, wooden crates or plywood boxes with proper blocking and bracing are used to protect the flanges and stem. All packaging is suitable for long-distance ocean freight. -
Q: Are spare parts like seats and seals available separately?
A: Yes, we maintain an inventory of critical spare parts for our valve models. We recommend keeping a set of spare seals and gaskets as part of onboard spares to facilitate quick maintenance if needed. -
Q: What is the difference between PN40 and Class 300 rating?
A: PN40 is a metric pressure rating (40 bar at room temperature). Class 300 is an ASME rating (approximately 50 bar at room temperature, depending on material). For this stainless steel valve, both ratings indicate a similar high-pressure capability. The specific rating applicable depends on the piping system standard your project follows.
