As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in supplying robust and reliable fluid control solutions for demanding marine environments. Our Marine Butterfly Valve, backed by a comprehensive Mill Test Report and a solid 2-Year Warranty, represents our commitment to quality and customer confidence. This valve is engineered to provide dependable, low-maintenance performance in seawater, ballast, cooling, and other critical shipboard systems, helping vessel operators ensure safety and operational efficiency.
Key Features & Technical Advantages:
- Designed for Marine Duty: Constructed from corrosion-resistant materials like stainless steel or duplex steel to withstand seawater, saline atmospheres, and varying temperatures.
- Compact & Lightweight Design: Butterfly valves offer a space-saving and weight-saving advantage compared to other valve types, crucial for marine applications where space and weight are optimized.
- Quick Operation & Good Flow Control: The 90-degree rotation from fully open to fully closed allows for rapid actuation. The disc design provides effective flow modulation and shut-off.
- Multiple Actuation Options: Available with manual hand lever, gearbox, pneumatic actuator, or electric actuator to suit different automation levels and power availability on board.
- Reliable Sealing: Utilizes resilient seats (EPDM, PTFE) or metal seats for tight shut-off, minimizing leakage and ensuring system integrity.
- Documented Quality: Each valve is supplied with a Mill Test Report (MTR) detailing material chemical composition and mechanical properties, providing traceability and proof of material conformity.

Frequently Asked Questions (FAQ):
-
Q: What is a Mill Test Report (MTR), and why is it important for a marine valve?
A: A Mill Test Report is a certificate from the material manufacturer that provides the chemical composition and mechanical properties (like tensile strength, hardness) of the steel used for the valve body and disc. In marine applications, verifying material grade (e.g., 316 stainless for corrosion resistance) is crucial for long-term performance. Our supplied MTR gives you documented proof of material quality. -
Q: Does the 2-year warranty cover all parts and under all operating conditions?
A: The warranty covers defects in materials and workmanship under normal operating conditions as defined in the product specifications. It typically covers the valve body, disc, stem, and seat. Specific warranty terms are provided with the product. -
Q: What are the main differences between Lug type and Wafer type butterfly valves for marine use?
A: Lug type valves have threaded lugs (or bolts) on the body, allowing them to be bolted directly to a flange without nuts on the opposite side, suitable for end-of-line service. Wafer type valves are designed to fit between two flanges and are bolted through using the flange bolts. The choice depends on your piping layout and installation requirements. -
Q: Can this valve be used for seawater ballast systems?
A: Yes, provided the material selection is appropriate. We recommend stainless steel (316 or 316L) or duplex steel valves with EPDM or PTFE seats for seawater ballast applications to handle corrosion and abrasion. -
Q: Are pneumatic or electric actuators available for remote operation?
A: Yes. We offer the valve as a complete package with various actuators (pneumatic, electric) to enable remote and automated control, which is common in modern marine systems. -
Q: What pressure class is typical for these marine butterfly valves?
A: Standard offerings are often rated PN16 (approx. Class 150). Higher pressure ratings (PN25/Class 300, etc.) can be provided based on your specific design requirements. -
Q: Do you provide custom face-to-face dimensions or special coatings?
A: While we supply valves per standard dimensions (ISO, ANSI/ASME), custom face-to-face lengths or special external coatings (like epoxy) can be discussed as optional features for specific projects. -
Q: How does your export experience benefit international buyers?
A: With an annual export value of US$1-1.5 Million and shipments from major Chinese ports (Shanghai, Guangzhou, Hongkong, Beijing), we have established procedures for international documentation, packaging, and logistics to markets worldwide, ensuring a smooth procurement process for you.
