Certification ISO9001 Quality Management System

As a professional manufacturer with a strong focus on marine and industrial fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our high-performance Marine Explosion Proof Electric Butterfly Valve with Remote PLC Interface. Engineered for the demanding conditions of offshore platforms, shipboard systems, and coastal processing facilities, this valve combines robust explosion-proof safety with advanced automated control. Designed and manufactured under stringent ISO9001 quality management protocols, our valve provides reliable, remote-operated flow regulation, ensuring operational safety and efficiency in hazardous environments where flammable gases or vapors may be present.

Core Product Features & Technical Advantages:

Intrinsically Safe Design: The electric actuator and valve housing are constructed with explosion-proof enclosures rated for marine and industrial hazardous areas (Zones 1 & 2). This design prevents internal sparks or excessive heat from igniting surrounding flammable atmospheres, a critical requirement for oil tankers, chemical carriers, and offshore rigs.
Seamless PLC Integration: Equipped with a standard remote PLC interface (typically 4-20mA analog signal or Modbus RTU), this valve allows for centralized control and monitoring from a safe distance. It can be easily integrated into existing Distributed Control Systems (DCS) or Supervisory Control and Data Acquisition (SCADA) systems for automated process control.
Rugged Construction for Marine Use: The valve body is available in materials like Cast Steel (WCB), Stainless Steel (CF8/CF8M), or Ductile Iron, offering excellent corrosion resistance against seawater, salty air, and various chemicals. All external fasteners and components feature anti-corrosion treatments.
Versatile Sealing Options: The disc seat is available in EPDM for general water and seawater, PTFE for high chemical resistance and a wider temperature range, or Viton (FKM) for hydrocarbon-based fluids. This ensures a bubble-tight seal and long service life across different media.
Precise and Reliable Actuation: The electric actuator provides precise 0-90° positioning with positional feedback. It features overload protection, manual override capability for emergency operation, and is designed for high cycle life with minimal maintenance.
Flexible Configuration: Available in Wafer, Lug, and Flanged connection types to suit various pipeline standards. A wide range of nominal diameters from DN50 to DN600 (2" to 24") caters to different flow capacity requirements.

Frequently Asked Questions (FAQ):

Q: What specific explosion-proof certification does this valve hold?
A: The valve is designed and manufactured according to explosion-proof principles (like Ex d, Ex e) suitable for marine hazardous areas. The specific certification mark (e.g., ATEX, IECEx) can be provided upon request and is often customized based on the project's regional requirements and the customer's specifications.
Q: Can this valve be used for controlling seawater directly?
A: Yes, absolutely. When ordered with a valve body material like Stainless Steel (316/316L) and an EPDM seat, it is highly suitable for seawater service, offering excellent resistance to chloride-induced corrosion.
Q: How is the remote PLC interface configured? Do you provide communication protocols?
A: The standard interface includes terminals for power, control signal (e.g., 4-20mA), and position feedback. Common communication protocols like Modbus RTU are available as an optional feature. Our technical team can assist with the configuration details for seamless integration into your PLC or DCS.
Q: What is the lead time for an order of these valves?
A: Lead time depends on the order quantity, valve size, and material specifications. Standard configurations typically have shorter lead times. We provide estimated timelines upon receipt of your detailed inquiry to ensure transparency.
Q: Do you offer actuators with different torque outputs?
A: Yes, we provide electric actuators with a range of torque outputs to match the required operating torque of the valve based on size, pressure, and media. Selecting the correct actuator ensures reliable operation and is part of our quotation process.
Q: Is on-site technical support or installation guidance available?
A: We provide comprehensive installation and operation manuals with each shipment. For complex projects, remote technical support is available. On-site support can be discussed and arranged based on project scope and location.
Q: Can the valve be customized for a different voltage supply, like 440VAC?
A: Yes, customization for various power supply voltages and frequencies is possible. Please specify your requirements during the inquiry stage so we can configure the actuator accordingly.
Q: What is your warranty policy for this product?
A: We offer a standard warranty against manufacturing defects. The specific warranty period and terms are provided with the commercial proforma invoice and are based on the product configuration and application.
