As a leading manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance GB/T3036 Standard Marine Butterfly Valve. Engineered specifically for demanding ballast water treatment applications, this valve delivers reliable flow control under pressures up to PN1.6MPa. Our decade of experience in serving global maritime markets ensures this product meets the rigorous standards required for shipboard operation, combining durability with precise functionality to protect your critical systems.

This marine-grade butterfly valve is designed to be a robust and cost-effective solution for managing ballast water flow. Its compact wafer or lug design allows for easy installation and maintenance in space-constrained piping systems commonly found on vessels. The valve's construction prioritizes corrosion resistance and long service life, even in the harsh saline environment of seawater handling.

Key Features & Technical Advantages:

Standard Compliance: Manufactured in strict accordance with the Chinese national standard GB/T3036, ensuring dimensional interchangeability, performance reliability, and quality consistency.
Pressure Versatility: Rated for PN0.6, 1.0, and 1.6MPa, providing flexibility for various system pressure requirements within ballast water treatment setups.
Superior Sealing: Features a resilient seat (EPDM/NBR/PTFE options) that ensures bubble-tight shut-off, preventing leakage and protecting against cross-contamination of ballast water.
Corrosion Resistance: Available with body materials like ductile iron with epoxy coating or stainless steel, and disc options including nickel-plated or stainless steel, to withstand corrosive seawater.
Low Torque Operation: The streamlined disc design and high-quality seat material minimize operating torque, allowing for smooth manual operation with a lever or efficient actuation with gear or electric actuators.
Bi-Directional Flow: Suitable for flow in both directions, simplifying piping system design and installation.

Frequently Asked Questions (FAQ):

Is this valve suitable for seawater applications?
Yes, it is specifically designed for marine applications like ballast water treatment. We offer material combinations such as epoxy-coated ductile iron or stainless steel bodies with corrosion-resistant discs and seats (e.g., EPDM, NBR) to handle seawater effectively.
What is the difference between wafer and lug type connections?
A wafer-type valve is installed between two flanges using longer bolts. A lug-type valve has threaded inserts (lugs) on both sides, allowing it to be bolted directly to each flange, which can be beneficial for end-of-line service or easier maintenance.
Can this valve be operated automatically?
Absolutely. While standard models come with a lever or gear operator, they can be easily fitted with pneumatic or electric actuators for remote and automated control, which is common in modern ballast water treatment systems.
Does it comply with international standards like ISO or ANSI?
This valve is manufactured to the Chinese GB/T3036 standard. While it shares many dimensional and performance characteristics with other standards, specific compliance with ISO or ANSI should be confirmed based on your project specifications. We can advise on comparability.
What is the delivery time for large sizes (e.g., DN600 and above)?
Delivery time varies based on material selection, actuation type, and order quantity. Standard materials in common sizes may have shorter lead times. We recommend contacting our sales team with your specific needs for an accurate timeline.
Are spare parts like seats and seals available?
Yes, as the manufacturer, we maintain an inventory of critical spare parts. We recommend purchasing a seal kit for preventative maintenance to ensure long-term valve performance.
What pressure rating should I choose for my ballast water system?
The required pressure rating depends on your system's maximum working pressure. PN1.0MPa (10 bar) is common for many ballast applications, but we offer PN0.6, 1.0, and 1.6MPa to match your design. Our engineers can assist in selection.
Do you provide documentation like test reports or material certificates?
Standard documentation includes a commercial invoice, packing list, and general quality certificate. Detailed test reports (e.g., pressure test) or material certificates are available upon request.
