As a leading manufacturer specializing in industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Explosion Proof Electric Gate Valve, engineered for the most demanding offshore and marine applications. Established in 2016 and backed by ISO9001 certified quality management, we understand the critical need for reliability and safety in hazardous environments. This valve is designed to provide secure, remote fluid flow control in potentially explosive atmospheres, offering peace of mind and operational efficiency for your marine and offshore projects.
Core Product Features & Technical Advantages:
- Robust Explosion-Proof Design: The valve and its electric actuator are housed in a specially engineered enclosure that prevents internal sparks or high temperatures from igniting surrounding flammable gases or dust, making it suitable for Zone 1 and Zone 2 hazardous areas.
- Precise Electric Actuation: Equipped with a reliable 380V AC electric actuator, it allows for easy remote operation and integration into automated control systems (DCS/SCADA), reducing manual labor and enhancing safety.
- Wide Size Compatibility: Available in a comprehensive range from DN50 to DN200, it caters to various pipeline dimensions commonly used in marine engineering, shipbuilding, and offshore platforms.
- Superior Construction Materials: Manufactured from high-grade cast steel, stainless steel, or ductile iron, the valve body ensures exceptional corrosion resistance against seawater and harsh chemicals.
- Dual Operation Mode: Features a manual override function on the actuator, ensuring flow control can be maintained even during power failures or for maintenance purposes.
- Excellent Sealing Performance: Options include metal-to-metal sealing for high-temperature applications or resilient seating (EPDM/NBR) for tight shut-off in standard conditions, minimizing leakage risks.

Frequently Asked Questions (FAQ):
-
Q: What defines an "explosion-proof" valve in marine contexts?
A: In marine and offshore settings, an explosion-proof valve is designed with enclosures that can contain any internal explosion and prevent sparks or hot surfaces from igniting external flammable atmospheres (like fuel vapors). Our valves are engineered to meet the stringent requirements of international standards for such hazardous areas. -
Q: Can this electric gate valve be operated manually if needed?
A: Yes, absolutely. The electric actuator is equipped with a manual handwheel or lever for override operation. This is a critical feature for emergency situations, maintenance, or during power outages. -
Q: Are specific certifications like ATEX or IECEx included?
A> Our valves are designed and manufactured to be compliant with the principles of ATEX and IECEx standards for explosion-proof equipment. The specific certification for a unit can be provided upon request and is often tailored to the customer's project requirements and the intended zone of operation. -
Q: What is the lead time for an order of DN150 valves?
A> Lead times vary based on order quantity, material selection, and specific configuration. Generally, for standard materials like WCB cast steel, lead times can range from 4 to 8 weeks. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: Is the 380V power supply compatible with international voltages and frequencies?
A> The standard actuator is configured for 380V AC, 3-phase, 50/60Hz, which is a common industrial power standard globally. We can also provide actuators for other voltage specifications (e.g., 440V, 220V) upon request to match your local grid. -
Q: What maintenance does this valve typically require?
A> Maintenance is minimal. It primarily involves periodic checks of the actuator's lubrication, electrical connections, and seal integrity. The robust design of the gate valve itself requires infrequent intervention under normal operating conditions. -
Q: Can you provide valves with different flange standards (ASME, DIN, JIS)?
A> Yes, we offer customization for flange connections. Our standard production covers common standards like ASME B16.5 and DIN/EN, but we can manufacture to other standards such as JIS, BS, or GOST based on your technical drawings or specifications. -
Q: What is the maximum working pressure for the PN40 rating?
A> The PN40 rating indicates a nominal pressure of 40 bar. The maximum allowable working pressure (MAWP) depends on the material and temperature, but at ambient temperature, it typically corresponds to 40 bar. Detailed pressure-temperature charts are available for each material grade.
