As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve is dedicated to providing reliable and high-performance fluid control solutions for the demanding marine industry. Our Marine Electric Regulating Butterfly Valve is engineered to meet the rigorous standards of shipboard and offshore applications, combining precise electric actuation with robust valve construction. We understand that operational reliability and compliance are paramount at sea, which is why every valve is supplied with a comprehensive Mill Test Report and backed by a solid 2-year warranty, offering you confidence and peace of mind.
Core Product Features & Technical Advantages:
- Precise Electric Regulation: Equipped with a high-quality electric actuator featuring modulating control (4-20mA or other signal feedback). This allows for precise flow control, automated operation integration with ship control systems, and remote monitoring capabilities, enhancing operational efficiency.
- Robust Marine-Grade Construction: The valve body and disc are manufactured from materials specifically selected for marine environments, such as cast steel with epoxy coating, 316 stainless steel, or other corrosion-resistant alloys, ensuring long-term durability against seawater and harsh conditions.
- Superior Sealing Performance: Features a resilient seat made from EPDM, NBR, Viton, or PTFE, providing bubble-tight shut-off and excellent resistance to wear, temperature variations, and the chemicals commonly found in marine systems.
- Versatile Configuration Options: Available in wafer, lug, or flanged designs to suit various piping layouts. Sizes are customizable from DN50 (2") to DN600 (24") with pressure ratings including PN10/16/25 and ANSI 150/300, ensuring a perfect fit for your specific application.
- Enhanced Safety & Reliability: The fail-safe options (fail-open or fail-close) in the electric actuator ensure system safety in case of power loss. The design minimizes pressure drop and offers smooth, low-torque operation, reducing stress on the actuator and piping.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of an electric regulating valve over a manual or pneumatic one for marine use?
A: Electric regulating valves offer precise, automated flow control via input signals (e.g., 4-20mA), enabling seamless integration with shipboard control systems for processes like ballast management or cooling, improving accuracy and reducing crew workload. -
Q: Does the valve come with the electric actuator pre-assembled and tested?
A: Yes, the electric actuator is typically mounted, aligned, and functionally tested at our factory before shipment, ensuring a ready-to-install unit and saving you time and effort on-site. -
Q: What does the "Full Mill Test Report" include, and why is it important?
A: The MTR is a traceability document from the material mill, detailing the chemical composition and mechanical properties (yield/tensile strength, etc.) of the valve body/disc material. It's crucial for quality verification and is often required by shipyards and classification societies. -
Q: Can this valve be used for seawater applications?
A: Absolutely. We recommend specific material combinations like 316 stainless steel body/disc with an EPDM or Viton seat for excellent corrosion resistance against seawater. The exact specification can be customized based on your service conditions. -
Q: What happens if there is a power failure? Will the valve position change?
A: The electric actuator can be specified with a fail-safe feature (spring return). Upon power loss, it will automatically drive the valve to a pre-set safe position (fully open or fully closed) as required by your system design. -
Q: Is the 2-year warranty comprehensive?
A: The standard warranty covers defects in materials and workmanship under normal use for both the valve and the actuator for a period of two years from shipment. Specific warranty terms are provided with the commercial documentation. -
Q: Do you offer valves suitable for high-pressure marine services?
A: Yes. While standard ratings are PN16/ANSI 150, we can supply valves designed for higher pressures such as PN25 or ANSI 300. Please specify your pressure requirements when inquiring. -
Q: Can you provide valves with specific certifications for different maritime regions?
A: As an ISO9001 certified manufacturer, our production process supports necessary certifications. While we supply valves globally, specific end-product approvals (like ABS, DNV, etc.) can be discussed and arranged based on your project needs.
