As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance Durable Hydraulic Wafer Butterfly Valve, engineered specifically for the demanding environment of shipboard cargo oil transfer. Since our establishment in 2016, we have focused on delivering robust and reliable flow control solutions for the global maritime and industrial sectors. This valve is a testament to our commitment to quality, designed to ensure safe, efficient, and leak-free operation during critical loading and unloading operations. We understand the challenges of marine applications, where corrosion resistance, durability, and minimal maintenance are paramount, and our product is built to exceed these expectations.
Core Product Features & Technical Advantages:
- Superior Durability & Construction: The valve body is precision-cast from high-grade ductile iron, carbon steel, or stainless steel, offering exceptional strength and resistance to the corrosive effects of seawater and various crude oils. The disc is designed for optimal flow with minimal pressure drop.
- Reliable Sealing Performance: Features a resilient seat made from EPDM, NBR, or PTFE, ensuring a bubble-tight seal in both directions. The seat is replaceable, extending the valve's service life and reducing long-term operating costs.
- Robust Hydraulic Actuation: Equipped with a heavy-duty hydraulic actuator that provides high torque output for positive opening and closing, even under high differential pressures. The actuator is designed for fail-safe operation (spring return or double-acting options available).
- Compact & Lightweight Wafer Design: The wafer-style body fits snugly between pipe flanges, reducing overall weight and space requirements—a critical advantage in space-constrained shipboard piping systems.
- Easy Installation & Maintenance: The simple design allows for quick installation between ANSI or DIN standard flanges. The stem is sealed with multiple sealing rings to prevent external leakage, and maintenance can be performed with the valve in-line.
- Versatile Application Readiness: While optimized for marine cargo oil transfer, this valve is also suitable for other shipboard services such as ballast, bilge, fuel oil, and freshwater lines, as well as onshore oil and gas pipelines.

Frequently Asked Questions (FAQ):
-
Q: Is this valve suitable for handling different grades of crude oil and fuel?
A: Yes. With appropriate seat material selection (typically EPDM or NBR), this valve is designed to handle a wide range of petroleum-based products, including various crude oils, marine diesel oil (MDO), and heavy fuel oil (HFO). -
Q: Can the hydraulic actuator be integrated with the ship's existing hydraulic power unit?
A: Absolutely. Our hydraulic actuators are designed to be compatible with standard marine hydraulic systems. We can specify the required oil flow, pressure, and connections to match your ship's system upon request. -
Q: What is the lead time for standard sizes?
A: For standard configurations and materials, our typical lead time is 4-6 weeks. Expedited production may be available for urgent requirements. -
Q: Do you offer a lug-style version instead of wafer?
A: Yes. While the standard product is a wafer type, a lug-style body is available as an option. The lug design allows for dead-end service and easier removal of downstream piping. -
Q: How do you ensure corrosion resistance for marine use?
A: We offer body materials like stainless steel (SS316) and apply protective coatings (epoxy, nickel plating) on ductile iron and carbon steel bodies as standard or optional features to combat saltwater corrosion. -
Q: What kind of testing is performed on these valves before shipment?
A: Each valve undergoes rigorous testing, including a shell test (body strength) and a seat leakage test per API 598 or equivalent standards to ensure integrity. -
Q: Are spare parts like seals and seats readily available?
A: Yes. We maintain an inventory of common spare parts and can provide seal kits and replacement seats to support maintenance schedules and minimize vessel downtime. -
Q: Can you provide valves with specific certifications for certain flag states or classification societies?
A> We can discuss certification requirements. Our manufacturing process is ISO9001 certified, and we work with clients to meet specific needs from classification societies like ABS, DNV, LR, etc., which may involve additional inspection and documentation.
