As a specialized manufacturer with a foundation in ISO9001 quality management since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our DNV GL Approved Marine Explosion Proof Electric Gate Valve. Engineered for the demanding environments of the global maritime and offshore industries, this valve combines certified safety with advanced remote operability. We understand that reliability and compliance are non-negotiable in marine applications, which is why this product is designed to deliver precise flow control, enhanced safety, and operational efficiency for shipboard systems, oil platforms, and other hazardous area installations. Our annual export experience across markets from North America to Southeast Asia ensures this valve meets international expectations.
Core Features & Technical Advantages:
- Certified Safety & Compliance: The valve holds DNV GL approval, a globally recognized standard for marine equipment. Its explosion-proof construction (typically rated Ex d IIC T6) is designed to prevent ignition in atmospheres containing flammable gases, dust, or vapors, making it suitable for engine rooms, pump rooms, and fuel handling areas.
- Advanced Remote Control Capability: Integrated electric actuator enables remote operation from a control room or bridge. This feature is crucial for:
- Enhancing personnel safety by reducing the need for manual intervention in hazardous zones.
- Improving operational efficiency through centralized control and integration with SCADA or ship automation systems.
- Allowing for quick emergency shutdown procedures.
- Robust & Durable Construction: Manufactured from high-grade materials like cast steel, ductile iron, or stainless steel to withstand corrosive marine environments, high pressures, and mechanical stress.
- Reliable Sealing Performance: Features a resilient seat (often stainless steel or reinforced elastomer) and a precision-machined gate to ensure bubble-tight shut-off, minimizing leakage and ensuring system integrity.
- Versatile Configuration Options: Available in various pressure ratings (PN10 to PN40), sizes, and connection types (flanged per ANSI, DIN, JIS, or GB standards) to suit diverse pipeline specifications.
- Fail-Safe Options: Electric actuators can be configured with fail-safe modes (fail-open or fail-close) to ensure the valve moves to a predetermined safe position in case of power loss, critical for safety-critical applications.

Frequently Asked Questions (FAQ):
-
Q: What does "DNV GL Approved" mean for this valve?
A: DNV GL is a leading international marine classification society. Their approval signifies that the valve has been designed, manufactured, and tested to meet stringent safety, performance, and quality standards specific to marine environments. It is often a mandatory requirement for equipment installed on classified vessels and offshore platforms. -
Q: Can this valve be operated manually if the power or control system fails?
A: Many of our electric actuator models are equipped with a manual override feature, typically a handwheel or crank. This allows for manual operation in emergencies or during maintenance, ensuring operational continuity. -
Q: What is the typical lead time for this product?
A: Lead time varies based on specifications and order quantity. Standard configurations often have shorter lead times. We provide accurate timelines upon receipt of your detailed inquiry and can leverage our established supply chain for efficient delivery. -
Q: Is the remote control system included, and what communication protocols are supported?
A: The electric actuator with basic control signals (like 4-20mA) is integral. For full remote control systems involving control panels, PLC integration, or specific protocols (Modbus, Profibus), these are available as optional accessories or customizable solutions. We can tailor the control package to your system architecture. -
Q: How do you ensure the valve's durability in seawater applications?
A: We offer body materials like ASTM A216 WCB (carbon steel) with protective coatings (epoxy, galvanization) or superior materials like CF8 (304 SS) and CF8M (316 SS) for enhanced corrosion resistance. Material selection is guided by the specific media and environmental conditions. -
Q: Do you provide installation and maintenance guidance?
A: Yes, comprehensive installation, operation, and maintenance manuals are provided with each valve. Additionally, our technical team is available for consultation to ensure proper installation and long-term performance. -
Q: Can you provide valves with certifications other than DNV GL?
A: While this specific product is highlighted with DNV GL approval, we can discuss other relevant marine and industrial certifications (such as those from other classification societies or regional standards) based on your project requirements. Please inquire for specific needs. -
Q: What after-sales support do you offer for international clients?
A: We provide standard warranty coverage. Given our extensive export experience to markets worldwide, we have established channels for technical support, spare parts supply, and troubleshooting. Support is accessible via email, phone, and online communication tools.
