As a professional manufacturer specializing in industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Marine Pneumatic Actuated Butterfly Valve. Established in 2016 and backed by ISO9001 certification, we have consistently delivered reliable flow control solutions to global markets, including North America, South America, Europe, Asia, Africa, and Oceania. Our expertise in marine applications ensures that this valve is engineered to withstand the demanding conditions of offshore and shipboard environments. Every unit is supplied with a comprehensive Mill Test Report, guaranteeing material traceability and quality assurance from the foundry to your project site.
This valve is designed for precise and efficient on/off or modulating control of fluids in marine piping systems. The integration of a robust pneumatic actuator enables remote operation, which is crucial for automated processes and hard-to-reach locations onboard vessels or offshore platforms.
Key Features & Technical Advantages:
- Rugged Marine-Grade Construction: The valve body is crafted from high-grade materials such as cast iron, ductile iron, or stainless steel (AISI 316/316L), offering superior resistance to corrosion from seawater, marine atmospheres, and various chemicals.
- High-Performance Sealing: Features a variety of seat materials like EPDM, NBR, or PTFE, ensuring bubble-tight shut-off and long service life even with abrasive media or under frequent cycling.
- Efficient Pneumatic Actuation: The double-acting or spring-return pneumatic actuator provides fast, reliable operation. It is designed for compatibility with standard marine control air supplies (typically 4-7 bar).
- Versatile Connection & Sizing: Available in wafer, lug, or flanged designs to suit different piping layouts. We offer a wide size range to meet diverse system requirements.
- Low Torque Operation: The disc design minimizes operating torque, reducing the size and cost of the required actuator and ensuring smoother, more energy-efficient operation.
- Compact & Lightweight Design: Compared to gate or globe valves, the butterfly design offers a significant space and weight saving, a critical factor in marine applications.
- Fail-Safe Options: Spring-return (single-acting) actuators are available to provide fail-open or fail-close functionality, enhancing system safety in case of air supply loss.
- Manual Override: Most models come equipped with a manual override mechanism, allowing for local operation during maintenance or emergencies.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of a pneumatic actuator for marine butterfly valves?
A: Pneumatic actuators offer fast, reliable operation and are ideal for remote or automated control systems common on ships and offshore platforms. They use compressed air, which is often readily available in marine environments, and are generally more cost-effective and easier to maintain than hydraulic systems for many applications. -
Q: Can this valve handle seawater applications?
A: Yes, absolutely. By selecting appropriate materials such as stainless steel (AISI 316/316L) for the body/disc and seawater-resistant elastomers like EPDM for the seat, the valve is well-suited for seawater service, including ballast, cooling, and bilge systems. -
Q: What does the "Mill Test Report" include, and why is it important?
A: The Mill Test Report (MTR) is a certificate from the material manufacturer (the mill). It details the chemical composition and mechanical properties (like tensile strength, yield strength) of the raw material used for critical valve parts (body, disc, stem). It is crucial for quality traceability, verifying material grade compliance, and is often a mandatory document for classification society approvals and project specifications. -
Q: Are these valves suitable for both on/off and modulating (throttling) control?
A: While butterfly valves can be used for moderate throttling, they are primarily excellent for on/off service. For precise modulating control, we recommend pairing the valve with a pneumatic positioner accessory, which we can supply as an optional extra. -
Q: What fail-safe modes are available with the pneumatic actuator?
A: We offer both double-acting (air-to-open, air-to-close) and spring-return single-acting actuators. Spring-return models provide fail-open or fail-close action: in case of air supply failure, the spring automatically moves the valve to a predetermined safe position (fully open or fully closed). -
Q: Do you offer customization for specific flange standards or special coatings?
A: Yes, customization is a key strength. We can manufacture valves to match various international flange standards (ANSI, DIN, JIS, BS). Special epoxy coatings, rubber lining, or other surface treatments for enhanced corrosion protection are also available upon request. -
Q: What is the typical lead time for an order?
A: Lead time depends on the order quantity, specifications, and material availability. For standard configurations, it typically ranges from 15 to 45 days. We provide accurate lead time estimates with every quotation. -
Q: Can you provide valves with specific certifications for marine classification societies?
A: While our standard production follows ISO9001, obtaining specific approvals from classification societies like ABS, DNV, LR, BV, etc., involves project-specific audit and testing procedures. We have experience in supplying valves for such projects and can discuss the certification process based on your requirements.
