As a leading manufacturer with ISO 9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Manual GB/T3036 Butterfly Valve DN300. Engineered for demanding industrial water pipeline applications, this valve offers a reliable and cost-effective solution for flow control. With over seven years of manufacturing expertise since our establishment in 2016, we have supplied high-performance valves to a global market, including North America, Europe, and Southeast Asia. This DN300 butterfly valve is designed for durability and ease of operation, making it an ideal choice for water treatment plants, cooling systems, and general industrial water distribution networks.
This valve is constructed to meet the rigorous GB/T 3036 standard, ensuring compatibility and performance within Chinese and international industrial specifications. The design prioritizes a tight seal and smooth operation over a long service life, even under continuous use in water service.
Key Features and Technical Advantages:
- Robust Construction: The valve body is typically made from high-grade ductile iron, providing excellent strength and corrosion resistance for water applications. The disc, the primary flow control component, is often constructed from stainless steel for enhanced durability.
- Reliable Sealing Performance: Equipped with a resilient seat made from materials like EPDM (Ethylene Propylene Diene Monomer) or NBR (Nitrile Butadiene Rubber), the valve ensures a bubble-tight shut-off, minimizing water leakage and loss.
- Efficient Flow Characteristics: The butterfly disc design offers minimal flow restriction when fully open, resulting in low pressure drop across the valve, which helps in reducing pumping energy costs.
- Simple and Quick Operation: The manual operation via a lever or an optional gear operator allows for rapid opening and closing. The 90-degree rotation from fully open to fully closed enables precise flow control.
- Easy Installation and Maintenance: The compact and lightweight wafer or lug design simplifies installation between pipeline flanges, saving space and labor time. Maintenance is straightforward, often requiring only seat replacement.

Frequently Asked Questions (FAQ)
-
Q: What is the main application of this DN300 butterfly valve?
A: This valve is primarily designed for industrial water pipeline systems. It is commonly used in water treatment plants, cooling water circuits, irrigation systems, and general industrial water supply and distribution networks where reliable on/off and throttling control is needed. -
Q: What does "GB/T 3036" mean, and is it compatible with international standards?
A: GB/T 3036 is a Chinese national standard for butterfly valves. Valves manufactured to this standard are generally designed to be dimensionally compatible with common international flange standards (like ANSI, DIN, JIS) for the same pressure rating, making them suitable for global projects. It signifies the valve meets specific design, material, and testing requirements. -
Q: Can this valve be used for fluids other than water?
A: While optimized for water, its suitability for other media (like mild chemicals, air, or gases) depends on the specific seat and seal material selected. Please consult with our technical team for your specific medium, temperature, and pressure conditions to ensure correct material compatibility. -
Q: What is the difference between Wafer and Lug connection types?
A: A Wafer-style valve is installed between two pipeline flanges using longer bolts that pass through both flanges. A Lug-style valve has threaded inserts (lugs) on the valve body, allowing it to be bolted directly to each flange, which can be beneficial for end-of-line service or easier removal. We offer both options. -
Q: Is a gear operator necessary for a DN300 valve?
A: For a DN300 valve, a manual lever is typically sufficient for standard water service at PN10/16 pressures. However, a gear operator is recommended if the system pressure is very high, if frequent operation is required, or if easier operation with reduced hand force is desired. It is available as an optional accessory. -
Q: What is the typical delivery time for this product?
A: For standard configurations, we generally maintain stock or can produce with a relatively short lead time. The exact delivery period depends on order quantity and current production schedule. We ship from major Chinese ports like Shanghai and Guangzhou, facilitating efficient logistics to our main markets worldwide. -
Q: Do you provide customization, such as different materials or coatings?
A: Yes, as a manufacturer, we offer customization options. This can include different body/disc materials (e.g., full stainless steel), special seat elastomers (Viton, PTFE), epoxy coatings for enhanced corrosion protection, or different actuator interfaces. Please inquire with your specific requirements. -
Q: What kind of after-sales support do you offer?
A: We provide comprehensive technical documentation, including dimensional drawings and material certificates. We also offer support for installation guidance and can supply spare parts like seat rings and seals to ensure the long-term operation of your valves.
