As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance GB/T3036 Marine Butterfly Valve, engineered specifically for demanding seawater applications. With years of expertise since our establishment in 2016, we understand the critical need for reliability and durability in marine environments. Our valves are designed to withstand the harsh conditions of seawater, offering superior sealing and long service life, which is why they are trusted by clients across North America, Southeast Asia, Europe, and beyond. This product represents our commitment to providing robust, standard-compliant solutions backed by comprehensive technical support, ensuring your marine systems operate smoothly and efficiently.
Our Marine Butterfly Valve is meticulously crafted to meet the stringent requirements of the GB/T3036 standard, ensuring compatibility and safety in various marine and offshore installations. The valve features a compact, lightweight design that simplifies installation and maintenance, even in confined spaces aboard ships or offshore platforms. The disc is precision-engineered to provide a bubble-tight seal, minimizing leakage and pressure drop, which is crucial for optimizing system performance and conserving energy. Furthermore, the valve's robust construction resists corrosion from saltwater, chemicals, and abrasive particles, making it an ideal choice for seawater cooling systems, ballast systems, firefighting lines, and other critical marine applications.
Key Features and Technical Advantages:
- Corrosion-Resistant Construction: Utilizes high-grade materials like stainless steel, ductile iron with epoxy coating, and specialized elastomers (EPDM, NBR) to combat seawater corrosion effectively.
- Excellent Sealing Performance: The resilient seat and precision disc ensure reliable, bidirectional sealing, even under fluctuating pressures and temperatures.
- Low Torque Operation: Designed for easy operation with manual levers, gear operators, or automated actuators (electric/pneumatic), reducing operational effort and wear.
- Versatile Configurations: Available in wafer and lug body designs to suit different piping system requirements and facilitate easy installation between flanges.
- Wide Size and Pressure Range: Catering to diverse system scales, from small auxiliary lines to large main pipelines.
- Compliance and Reliability: Manufactured in accordance with GB/T3036, ensuring dimensional interchangeability and performance consistency.

Q: Is technical documentation and support available for installation and maintenance?
A: Yes, comprehensive technical support is a key offering. We provide detailed installation manuals, dimensional drawings, material certificates, and our engineering team is available to assist with technical queries throughout the valve's lifecycle. -
Q: Can this valve be operated automatically?
A> Absolutely. While available with manual levers or gear operators, this butterfly valve can be easily fitted with electric or pneumatic actuators for remote or automated control, which is common in modern marine systems. -
Q: How does compliance with GB/T3036 benefit me as an international buyer?
A: The GB/T3036 standard ensures the valve has standardized dimensions, pressure ratings, and performance criteria. This guarantees interchangeability with other compliant components and provides a reliable benchmark for quality and safety, which is valued in global marine projects. -
Q: What is the typical lead time for an order?
A: Lead time depends on the order quantity, size, and configuration. Standard models may have shorter lead times, while customized orders (special materials, actuators) require additional production time. We provide accurate lead time estimates upon receipt of your specific requirements. -
Q: Do you offer customization for specific project needs?
A: Yes, we offer a high degree of customization. This includes special coatings, alternative materials for extreme conditions, specific face-to-face dimensions, and integration with various brands of actuators. Please share your specifications for a tailored solution. -
Q: What after-sales services do you provide?
A: Our after-sales support includes warranty coverage for manufacturing defects, provision of spare parts (like seals and discs), and ongoing technical consultation to ensure optimal valve operation and troubleshooting if needed. -
Q: Are your valves tested before shipment?
A> Yes, each valve undergoes rigorous factory testing, which typically includes shell tests and seat leakage tests according to relevant standards, to verify its pressure integrity and sealing performance before it is dispatched.
