As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is dedicated to providing reliable and high-performance fluid control solutions for the global market. We are proud to introduce our GB/T3036 Standard Butterfly Valve DN80, a product engineered for durability, ease of maintenance, and long-term cost-effectiveness. This valve is designed to meet the rigorous demands of various industrial applications, from water distribution and HVAC systems to chemical processing and general plant utilities. Understanding the critical need for minimal downtime and operational reliability, we have enhanced this standard product with an extended warranty and a complimentary replacement seal kit, offering our clients exceptional value and peace of mind. Our commitment to quality, backed by ISO9001 certification, ensures that every valve delivers consistent performance and meets international standards.
This butterfly valve is constructed to provide a tight seal and smooth operation over an extended service life. Its design adheres to the Chinese National Standard GB/T3036, which specifies the requirements for general-purpose butterfly valves, ensuring compatibility and reliability in a wide range of piping systems. The inclusion of a spare seal kit allows for quick on-site maintenance, significantly reducing repair time and associated costs.
Key Features and Technical Specifications:
- Robust Construction: The valve body is typically made from high-grade ductile iron or cast iron, providing excellent strength and corrosion resistance. The disc, which controls the flow, is commonly manufactured from stainless steel or coated ductile iron to prevent rust and ensure smooth rotation.
- Superior Sealing Performance: Equipped with a resilient seat made from materials like EPDM (for water), NBR (for oils), or PTFE (for chemicals). The seat design ensures a bubble-tight shut-off, minimizing leakage and enhancing system efficiency.
- Versatile Connection and Operation: Available in wafer, lug, or double-flanged designs to suit different piping configurations. Operation can be manual (via lever or gear operator) or automated (with electric or pneumatic actuators available upon request), offering flexibility for various control needs.
- Extended Service Life with Maintenance Kit: The standout feature is the included replacement seal kit. This proactive offering contains essential wear parts like the seat ring and seals, enabling preventative maintenance and swift repairs without waiting for spare parts, thus maximizing uptime.

Frequently Asked Questions (FAQ)
-
Q: What does the "Extended Warranty" cover for this butterfly valve?
A: The extended warranty provides coverage beyond standard terms for manufacturing defects in materials and workmanship. Specific duration and terms can be confirmed upon request with your order. It is a testament to our product's reliability. -
Q: What is included in the "Replacement Seal Kit"?
A: The kit typically contains the primary wear components, such as the resilient seat ring (O-ring or similar) and necessary gaskets or seals for the stem. It allows for essential maintenance to restore sealing performance without sourcing individual parts. -
Q: Is this DN80 valve compatible with ANSI flanges?
A: While designed to GB/T standards, flanged versions can be manufactured to match common international dimensions like ANSI B16.5 for PN16 pressure rating. Please specify your flange standard when inquiring to ensure compatibility. -
Q: Can I get this valve with an electric actuator?
A: Yes. The valve can be supplied as a manual unit (lever/gear) or fitted with electric or pneumatic actuators. Actuator specifications (torque, voltage, control signal) should be provided for a precise quotation. -
Q: What media is the standard EPDM seat suitable for?
A: The standard EPDM seat is excellent for cold and hot water, steam (up to 120°C), weak acids, alkalis, and air. For oils, fuels, or specific chemicals, NBR or PTFE seats are recommended alternatives. -
Q: What is the lead time for an order of these valves?
A: Lead time depends on order quantity and configuration. Standard manual valves are often available from stock or have a shorter production cycle. We ship efficiently from multiple ports to ensure timely delivery globally. -
Q: Do you provide technical drawings or CAD files?
A: Yes. Detailed dimensional drawings in PDF or CAD format (like DWG) are available upon request to assist with your system design and integration planning. -
Q: How does the GB/T3036 standard compare to other international standards?
A: GB/T3036 is a comprehensive Chinese national standard for general-purpose butterfly valves, covering dimensions, materials, pressure ratings, and testing. It ensures a quality level comparable to other recognized industrial standards, making the valve suitable for a wide range of applications worldwide.
