As a leading manufacturer with a strong global footprint, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized Marine Butterfly Valve with Actuator Mounting Pad. Engineered for critical marine applications, this valve is designed to deliver reliable and efficient control in demanding bilge and ballast systems. With our commitment to quality backed by ISO9001 certification and extensive export experience across continents, we provide robust solutions that shipbuilders and marine engineers trust for performance and durability.

This valve is a cornerstone for safe and effective vessel operation. Its core value lies in providing a secure, leak-proof, and easily automated method for managing seawater intake, transfer, and discharge. The integrated actuator mounting pad is a key feature, enabling straightforward connection to electric, pneumatic, or hydraulic actuators for remote or automated control, which is essential for modern vessel management systems.

Key Features & Technical Advantages:

Rugged Construction for Marine Environments: Manufactured from corrosion-resistant materials like cast iron with epoxy coating, ductile iron, or stainless steel, the valve body withstands harsh seawater, bilge water, and atmospheric conditions.
Standardized Actuator Interface: The built-in mounting pad conforms to ISO 5211 standards, ensuring compatibility with a wide range of actuator brands and models. This simplifies procurement, installation, and future maintenance.
Superior Sealing Performance: Equipped with high-quality elastomer seats (EPDM, NBR) or PTFE, the valve ensures a bubble-tight shut-off, preventing unwanted water ingress or loss, which is critical for stability and safety in ballast operations.
Low Torque Operation: The streamlined disc design minimizes flow resistance and operating torque, reducing the size and cost of the required actuator and ensuring smooth, reliable opening and closing cycles.
Bi-Directional Flow Capability: The valve design allows for effective sealing in both flow directions, offering flexibility in system piping layout without compromising performance.
Compact & Lightweight Design: Compared to gate or globe valves, the butterfly valve offers a significant space and weight saving, a crucial factor in ship design where every kilogram counts.

Frequently Asked Questions (FAQ):

Q: Is this valve suitable for both bilge and ballast water service?
A: Yes, it is specifically designed for these applications. Material selections like epoxy-coated cast iron or stainless steel provide the necessary corrosion resistance for bilge water (often oily and debris-laden) and seawater used in ballast systems.
Q: What is the advantage of the ISO 5211 mounting pad?
A: The ISO 5211 pad is an international standard for actuator-to-valve interface dimensions. It guarantees interchangeability, allowing you to source actuators from different suppliers without compatibility concerns, offering flexibility and competitive pricing.
Q: Can you supply the valve with an actuator already installed?
A: Yes, we offer the valve as a complete package with electric, pneumatic, or hydraulic actuators. This is a common request, and we can pre-assemble, wire, and test the unit to save you time and labor on-site.
Q: What seat material do you recommend for seawater service?
A: For standard seawater temperature ranges, EPDM is a common and cost-effective choice. For higher temperatures or more aggressive fluids, Viton (FKM) or PTFE seats are available upon request.
Q: What is the typical delivery time for an order?
A: Delivery time depends on the order quantity, size, and material specifications. Standard configurations typically have shorter lead times. We provide clear timelines upon order confirmation and leverage our multi-port shipping options for efficient logistics.
Q: Do your valves come with any operational limits?
A: Yes, each valve has specified pressure and temperature ratings based on its materials. It is crucial to select the correct rating for your system's maximum working pressure and fluid temperature to ensure safe and reliable operation.
Q: Are spare parts like seals and gaskets readily available?
A: Absolutely. As the manufacturer, we maintain an inventory of common spare parts. We recommend keeping a set of critical seals on board for maintenance purposes, and we can supply these with the initial order.
Q: How does this valve compare to a gate valve for the same application?
A: Butterfly valves offer significant advantages: they are more compact, lighter, quicker to operate, and generally more cost-effective for on/off and throttling service in large diameters. They are often the preferred choice in modern marine piping systems.
