As a professional manufacturer with a strong foothold in the global valve industry since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our ATEX Certified Marine Explosion Proof Electric Gate Valve with Flanged Connection. Designed specifically for the demanding environments of marine and offshore applications, this valve combines robust construction with intelligent electric operation to deliver reliable, safe, and efficient flow control in potentially explosive atmospheres. Our commitment to quality, evidenced by our ISO9001 certification, ensures that each valve meets stringent performance and safety standards, providing our clients in regions from North America to Southeast Asia with a dependable solution for their critical operations.

This specialized gate valve is engineered to address the unique challenges of marine settings, where corrosion, high pressure, and the risk of explosive gases are constant concerns. Its core value lies in providing a fail-safe, remotely operable shut-off mechanism that enhances operational safety and reduces manual intervention in hazardous zones. By integrating an ATEX-certified explosion-proof electric actuator with a durable flanged gate valve body, we offer a seamless and compliant component for your piping systems.

Key Features & Technical Advantages:

ATEX-Certified Explosion Proof Design: The electric actuator and valve enclosure are specifically designed and certified to prevent ignition of surrounding explosive atmospheres (gas, dust), making it suitable for Zone 1 and Zone 2 hazardous areas on vessels and offshore platforms.
Electric Actuator Operation: Enables remote, automated, or centralized control via switchgear, PLC, or DCS systems. This reduces the need for personnel to access dangerous locations for manual operation, improving overall site safety.
Robust Flanged Connection: The flanged ends ensure a secure, leak-proof connection to pipeline systems, facilitating easier installation, maintenance, and high-pressure handling. Flanges conform to common standards like ANSI, DIN, JIS, or GB.
Superior Sealing & Durability: Utilizing advanced seat materials such as reinforced PTFE or stainless steel, the valve offers excellent sealing performance, low torque operation, and high resistance to corrosion, erosion, and seawater exposure.
Versatile Material Options: Valve bodies are available in carbon steel (WCB), stainless steel (CF8/CF8M), ductile iron, and other alloys to match specific fluid compatibility and corrosion resistance requirements.
Fail-Safe Options: Actuators can be configured with fail-open (FO) or fail-close (FC) functions, ensuring the valve moves to a predetermined safe position in case of power failure, critical for emergency shutdown systems.
Integrated Limit Switches & Position Indication: Provides real-time feedback on valve position (open/closed), which can be integrated into control panels for enhanced monitoring and system diagnostics.

Frequently Asked Questions (FAQ)

What does ATEX certification mean for this valve?
ATEX certification signifies that the valve's electric actuator and enclosure are designed and tested to prevent ignition in explosive atmospheres containing flammable gases, vapors, mists, or dust. It is a mandatory requirement for equipment used in designated hazardous zones within the European Union and many other regions, ensuring operational safety.
Can this valve be used for applications other than marine?
Yes. While specifically designed for marine corrosion resistance, its ATEX certification and robust construction make it suitable for any onshore or offshore industry with explosive atmospheres, such as oil & gas terminals, chemical plants, paint booths, or grain handling facilities.
What are the available flange standards and face types?
We typically supply flanges conforming to ANSI (ASME), DIN, JIS, or GB standards. Common face types include Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). Please specify your required standard and pressure class when inquiring.
Is the electric actuator waterproof or weatherproof?
The explosion-proof housing typically offers a high degree of ingress protection (e.g., IP66, IP67), making it dust-tight and protected against powerful water jets. This contributes to its suitability for outdoor and marine deck installations.
Do you offer different fail-safe modes for the actuator?
Yes. The electric actuator can be configured as fail-close (spring return to closed position on power loss) or fail-open (spring return to open position). Fail-in-place (no change) versions may also be available upon request.
How is the valve controlled and monitored?
Control is via standard electrical signals (e.g., open/close contact). The actuator usually includes built-in limit switches to indicate open/closed positions, with optional auxiliary switches, potentiometers for position feedback, or Profibus/Foundation Fieldbus communication modules for integration into control systems.
What is the lead time for standard and custom orders?
For standard specifications from our catalog, lead times are competitive. For custom configurations involving specific materials, sizes, or certifications, lead time will be confirmed upon receipt of your detailed requirements. Our multiple export ports help streamline logistics.
What kind of maintenance does this valve require?
Maintenance is minimal. Periodic checks of the actuator's electrical connections, lubrication of the stem (if required), and operational tests are recommended. The robust design aims for long service intervals even in tough conditions.
