As a professional manufacturer with a strong commitment to maritime safety and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Explosion Proof Electric Butterfly Valve. Engineered specifically for the demanding environments of the marine and offshore industries, this valve combines robust construction with intelligent electric actuation to deliver precise flow control where safety is paramount. Our years of experience since 2016, backed by ISO9001 certified manufacturing processes, ensure that every valve meets the stringent requirements of international marine standards, providing shipbuilders, shipowners, and offshore operators with a dependable solution for critical pipeline applications.
This valve is designed to excel in hazardous areas where flammable gases or vapors may be present. Its core value lies in providing fail-safe operation and exceptional sealing performance, ensuring the integrity of fuel, cargo, ballast, and cooling water systems on various vessels and offshore platforms.
Key Features & Technical Advantages:
- Intrinsically Safe Design: The integrated electric actuator and valve body assembly are housed in an explosion-proof enclosure certified for Zone 1 hazardous areas. This prevents any internal spark or high temperature from igniting the surrounding atmosphere, offering critical protection for personnel and assets.
- Full Compliance with Marine Regulations: The valve is meticulously designed and tested to comply with the International Maritime Organization (IMO) guidelines and the Safety of Life at Sea (SOLAS) convention. This ensures it meets the global benchmark for safety equipment on ships.
- Robust & Corrosion-Resistant Construction: Available in materials like 316 stainless steel, cast iron with epoxy coating, and duplex steel, the valve offers excellent resistance to seawater corrosion, chemicals, and harsh weather conditions, guaranteeing a long service life.
- Precise Electric Actuation: The electric actuator allows for remote operation, precise positioning (0-90° modulation), and easy integration with ship automation systems (IAS). Features include local control, remote signal control (4-20mA, 0-10V), and fail-safe modes (open/close/stop on power loss).
- Superior Sealing Performance: Utilizing high-grade seat materials like PTFE, EPDM, or Viton, the valve ensures bubble-tight shut-off, minimizing leakage and preventing cross-contamination between different fluids in the pipeline.
- Low Maintenance & High Reliability: The simple yet durable disc and seat design reduces wear and tear. The electric actuator is sealed and requires minimal maintenance, leading to lower lifecycle costs and reduced downtime.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "Explosion Proof" mean for this butterfly valve?
A: "Explosion Proof" signifies that the valve's electric actuator is housed in a specially reinforced enclosure. This enclosure is designed to contain any potential internal spark or explosion, preventing it from igniting flammable gases in the surrounding hazardous area (like a ship's engine room), thus ensuring operational safety. -
Q: Can this valve be used for both on/off service and flow regulation?
A: Absolutely. The electric actuator provides precise modulating control, allowing you to position the valve disc at any angle between fully open and fully closed. This makes it suitable for both simple shut-off applications and processes requiring accurate flow rate control. -
Q: Are specific IMO and SOLAS certificates provided with the valve?
A: While the valve is designed and manufactured to be fully compliant with the relevant IMO and SOLAS standards, formal certification for a specific vessel is typically issued by the classification society (like ABS, DNV, LR) after they review and approve the equipment for the project. We provide all necessary technical documentation to support this approval process. -
Q: What is the lead time for an order of these valves?
A: Lead times vary based on the order quantity, specific size, material, and actuator configuration. Standard models typically have a shorter lead time. We recommend contacting our sales team with your detailed specifications for an accurate production and delivery schedule. -
Q: How does the electric actuator handle a power failure?
A: The actuator can be configured with a fail-safe feature (spring return). Upon power loss, it will automatically drive the valve to a pre-set safe position—either fully open or fully closed—as required by your system's safety logic. -
Q: Is the valve suitable for seawater applications?
A: Yes, it is highly suitable. We recommend selecting a body material like 316 stainless steel or duplex steel and an appropriate seat material (such as EPDM or Viton) to ensure optimal corrosion resistance and longevity when handling seawater or other corrosive media. -
Q: Do you offer customization for different flange standards or voltage requirements?
A: Yes, customization is a key service we provide. We can manufacture valves to match various international flange standards (ANSI, JIS, DIN, etc.) and configure the electric actuator for different supply voltages (AC or DC) and control signals to meet your project's exact specifications. -
Q: What kind of warranty and after-sales support do you offer?
A: We stand behind the quality of our products. A standard warranty period is provided, covering manufacturing defects. Our technical support team is available to assist with installation guidance, troubleshooting, and sourcing spare parts if needed.
