Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of industrial valves since 2016, with annual export value exceeding US$1 million and shipments to over 20 countries and regions across North America, Southeast Asia, Europe, and the Middle East. Our Marine Explosion Proof Electric Butterfly Valve is specifically engineered for hazardous zone pump control, combining robust marine-grade design with certified explosion-proof performance. This valve delivers reliable flow regulation and isolation in explosive environments such as oil tankers, offshore platforms, and chemical processing facilities.
Built with premium materials and an intrinsically safe electric actuator, this butterfly valve ensures zero leakage and precise positioning even under extreme temperature and pressure conditions. The explosion-proof housing meets international safety standards for zone 1 and zone 2 hazardous areas, providing peace of mind for demanding marine and industrial applications. Below we detail the key features, specifications, and advantages that make this valve the preferred choice for pump control in dangerous environments.
Key Features & Benefits
- Explosion-Proof Electric Actuator: Designed to prevent ignition of surrounding flammable gases or dust. Actuator enclosure is sealed and flameproof, suitable for Zone 1 & Zone 2 hazardous locations.
- Marine-Grade Construction: Corrosion-resistant materials (stainless steel trim, epoxy-coated ductile iron body) withstand saltwater, humidity, and harsh marine environments.
- High Torque & Fast Response: Electric actuator provides consistent torque output for reliable opening/closing. Option for fail-safe (spring-return or battery backup) ensures safe shutdown in power loss.
- Bidirectional Sealing: Resilient seat (PTFE or reinforced rubber) achieves bubble-tight shut-off in both flow directions, complying with API 598 leakage requirements.
- Easy Integration: Standard flange connection (ISO 5211) allows direct mounting to the valve. Electrical interface accepts 4-20mA, MODBUS, or dry contact signals for remote control.
- Low Maintenance: Self-lubricating bushings and sealed actuator reduce service intervals. All external fasteners are stainless steel for long-term reliability.

Frequently Asked Questions (FAQ)
-
Q: What type of explosion-proof certification does this valve have?
A: Our explosion-proof actuator is built to recognized international standards (such as Exd II BT4) and can be customized to meet specific certifications like ATEX or IECEx. Please inquire with our sales team for your required certificate – we will provide a compatible configuration. -
Q: Can this valve be used for seawater applications?
A: Yes. We offer material options like duplex stainless steel disc and epoxy-coated ductile iron body that resist corrosion from saltwater. Additionally, the seat can be EPDM or Viton, which perform well in marine environments. We recommend confirming the exact medium and temperature for proper material selection. -
Q: What is the typical response time of the electric actuator for pump control?
A: The actuator’s response time depends on torque and voltage. For standard sizes (DN100-DN300), full stroke (90° rotation) takes between 15 to 45 seconds. Faster speeds are available upon request by selecting a higher-capacity actuator or specialized gearing. -
Q: Do you offer failsafe (spring-return) function?
A: Yes, we can equip the actuator with a spring-return mechanism or battery backup unit. In case of power loss, the valve will automatically close (or open, as specified) to ensure safe pump shutdown. Please note that failsafe options may increase actuator size and cost. -
Q: What is the difference between wafer and lug body styles? Which one should I choose for pump control?
A: Wafer style is lighter and more economical, but requires mating flanges to hold the valve in place. Lug style has threaded inserts that allow it to be bolted between flanges and can be used for end-of-line or isolation service. For pump control where downstream removal is common, lug style is often preferred. We can supply both. -
Q: How do I ensure the valve is compatible with my existing control system?
A: Our standard actuator accepts 4-20mA, 0-10V, or MODBUS signals. We can also integrate with Profibus, DeviceNet, or other protocols if specified. Please provide your PLC or DCS communication requirements during ordering, and we will match the interface. -
Q: What is the minimum order quantity (MOQ) and lead time?
A: MOQ is 1 piece for standard sizes. For special materials or large quantities (50+ pieces), lead time may extend to 30-45 working days. Contact our sales for current stock availability and expedited shipping options. -
Q: Do you provide warranty and after-sales support for international clients?
A: Yes, we offer an 18-month warranty from the date of shipment against defects in material and workmanship. We have a global network of partners and provide remote troubleshooting via email/phone. Spare parts can be shipped quickly from our Shanghai warehouse.
