As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and high-performance fluid control solutions for demanding marine environments. Our Marine Wafer Pneumatic Butterfly Valve with Solenoid is engineered to meet the rigorous standards of shipbuilding and offshore applications, offering precise flow control, robust construction, and dependable automation. With an annual export value exceeding US$1 million, we have established a strong presence in global markets from North America to Southeast Asia, ensuring our products are trusted for critical marine operations. This valve combines the simplicity of a wafer design with the power of pneumatic actuation and the control of a solenoid, making it an ideal choice for seawater cooling, ballast, firefighting, and fuel oil systems onboard vessels.
Core Design & Technical Specifications:
This valve is designed as a compact, bi-directional shut-off device installed between pipeline flanges, conforming to the Chinese national standard GB/T3036-94. The integration of a pneumatic actuator and solenoid valve allows for remote on/off or modulating control, which is essential for automated marine systems. Each valve is supplied with a comprehensive Mill Test Report (MTR), providing full traceability of materials and verification of mechanical properties, a critical requirement for ship classification society approvals.
- Superior Sealing Performance: The disc features a precision-machined edge that seals tightly against a resilient seat (EPDM, NBR, or PTFE), ensuring zero leakage for both liquid and gaseous media, even under varying pressure conditions.
- Corrosion Resistance for Marine Use: Standard body materials include ductile iron with epoxy coating or stainless steel (AISI 316/316L), providing excellent resistance to saltwater corrosion, ensuring long service life in harsh marine atmospheres.
- Compact & Lightweight Wafer Design: The wafer-style body requires less space and has a lower weight compared to lug-style or flanged valves, simplifying installation and reducing the overall weight of the piping system—a significant advantage in ship design.
- Reliable Pneumatic Actuation: The double-acting or spring-return pneumatic actuator provides fast, powerful, and fail-safe operation. It is suitable for continuous duty cycles and can be configured for fail-open or fail-close positions.
- Integrated Solenoid Control: The mounted solenoid valve facilitates easy electrical integration for automated control systems, allowing operation from the ship's control room or bridge with a simple electrical signal (24VDC, 110VAC, 220VAC).
- Low Maintenance & Easy Operation: The simple quarter-turn operation and robust construction minimize wear. The stem is sealed with high-quality O-rings and packing, requiring minimal maintenance over its lifespan.

Benefits for Your Marine Projects:
- Enhanced System Reliability: Automated control reduces manual intervention, minimizes human error, and ensures prompt response in critical situations like firefighting or ballast control.
- Simplified Classification Approval: The provision of a Mill Test Report for all pressure-containing parts supports the documentation process required by major ship classification societies (e.g., ABS, DNV, LR, BV).
- Cost-Effective Installation & Operation: The compact wafer design lowers installation time and cost. The pneumatic actuator uses compressed air, a readily available and safe power source onboard ships.
- Versatile Application Fit: Suitable for a wide range of shipboard services including chilled water, seawater, lubricating oil, dry bulk, and ventilation systems, thanks to customizable seat and body materials.
- Global Supply Chain Support: With major shipment ports in Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure flexible and timely logistics to shipyards and marine equipment suppliers worldwide.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a wafer-style butterfly valve for marine use?
A: The wafer design is compact and lightweight, which saves space and reduces the overall weight of the ship's piping system—a crucial factor in marine engineering. It installs between two pipeline flanges using through-bolts, making installation and future maintenance more straightforward compared to lug or flanged valves. -
Q: Can this valve be used for seawater service?
A: Yes, absolutely. For seawater applications, we recommend specifying a stainless steel body (AISI 316/316L) and an EPDM seat, which together offer excellent corrosion resistance and durability against saltwater. The standard epoxy-coated ductile iron is also a common and cost-effective choice for many seawater systems. -
Q: What does the "Mill Test Report Provided" mean, and why is it important?
A: A Mill Test Report (MTR) is a certified document from the material mill that details the chemical composition and mechanical properties (like tensile strength and yield strength) of the metal used for the valve's pressure-containing parts (body, disc, stem). It is a mandatory document for most ship classification society approvals (like ABS, DNV-GL) to ensure material traceability and quality. -
Q: What are the fail-safe options for the pneumatic actuator?
A: The actuator can be configured as double-acting (requires air to move in both directions) or spring-return (single-acting). Spring-return actuators provide a fail-safe function: upon air supply or power loss, the valve will automatically move to a pre-set "fail-open" or "fail-close" position, which is critical for safety in marine systems. -
Q: Is the solenoid valve included, and what are the electrical requirements?
A: Yes, the product includes a pilot solenoid valve mounted on the pneumatic actuator. Standard voltage options are 24VDC, 110VAC, and 220VAC. Please specify your required voltage and electrical connection type (e.g., conduit, junction box, plug) when ordering to ensure compatibility with your ship's control system. -
Q: Do you offer valves with different flange face standards to match existing piping?
A: Yes. While the valve conforms to the dimensional standard GB/T3036-94, the flange facing (RF, FF) and drilling can be manufactured to match other common standards such as ANSI B16.5, DIN, JIS, or specific customer drawings. Please provide your flange standard details for confirmation. -
Q: What is the typical lead time for an order?
A: Lead time depends on the size, material specification, and order quantity. Standard configurations typically have a shorter lead time. We recommend contacting our sales team with your specific requirements for an accurate production and delivery schedule. -
Q: Can you provide valves certified by specific marine classification societies?
A> We manufacture valves that meet the material and design requirements of major classification societies. Third-party inspection and certification by societies like ABS, BV, or DNV can be arranged upon request, which may involve additional testing, documentation, and costs.
