As a dedicated manufacturer with ISO9001-certified processes since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering reliable flow control solutions for demanding industrial applications. Our Industrial Process Line Butterfly Valve, engineered in strict compliance with the GB/T3036 standard and featuring a robust stainless steel disc, is designed to offer superior sealing performance, extended service life, and exceptional value for your process lines. We understand the critical need for dependable valves that minimize downtime and maintenance costs, which is why this valve is a cornerstone product in our portfolio, trusted by clients across North America, Southeast Asia, Europe, and beyond.
This butterfly valve is engineered for precision and durability in a wide array of industrial settings. Its core construction and design features are tailored to meet the rigorous demands of modern process industries.
- High-Performance Stainless Steel Disc: The heart of the valve is its disc, crafted from high-grade stainless steel (304 or 316). This material choice provides excellent corrosion resistance against a broad spectrum of media, including water, mild chemicals, oils, and gases. The disc's polished surface finish minimizes flow resistance and prevents particle adhesion, ensuring consistent operation and easy maintenance.
- GB/T3036 Standard Compliance: Manufactured in full accordance with the Chinese National Standard GB/T3036, this valve guarantees dimensional interchangeability, reliable pressure ratings, and standardized testing. This compliance provides peace of mind regarding quality, safety, and compatibility with existing piping systems designed to similar specifications.
- Versatile Body and Seat Options: The valve body is available in cast iron, ductile iron, or carbon steel to suit different pressure requirements and environmental conditions. The seat, crucial for a bubble-tight seal, can be selected from materials like EPDM for general purposes, PTFE for high-temperature or chemical resistance, or NBR for oil-based fluids, allowing for precise customization.
- Multiple Actuation Methods: To integrate seamlessly into any control scheme, the valve supports various actuation types. Choose from a simple manual lever for quick on/off service, a precision gear operator for larger sizes, or automated electric and pneumatic actuators for remote process control and integration into SCADA systems.
- Low Torque Operation & Bi-Directional Shut-off: The optimized disc and stem design ensures low operating torque, reducing wear on the actuator and making manual operation easier. The valve provides effective bi-directional shut-off, reliably sealing flow from either direction, which enhances its versatility in complex piping layouts.
Below is a summary of key technical specifications for common configurations:

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of the stainless steel disc in this butterfly valve?
A: The stainless steel disc offers superior corrosion resistance compared to coated or other metallic discs, significantly extending the valve's service life when handling water, mild chemicals, and other corrosive media. It also maintains a smooth surface to ensure consistent sealing. -
Q: Is this valve suitable for both on/off and throttling service?
A: While primarily designed for reliable on/off isolation, this valve can be used for moderate throttling applications, especially when paired with a suitable actuator (like an electric modulating type) and a PTFE seat for better flow control characteristics. -
Q: Can you provide valves with different end connections?
A: Yes. We offer standard connections including wafer type (for tight space between flanges), lug type (for end-of-line service or dead-end pressure), and double flanged ends. Specific flange standards (ANSI, DIN, JIS) can be discussed based on your piping system. -
Q: What is the lead time for an order of these valves?
A: Lead time depends on the order quantity, size, and specific configuration (like actuation). Standard configurations in common sizes often have shorter lead times. We provide accurate delivery estimates upon receipt of your detailed inquiry. -
Q: How does compliance with GB/T3036 benefit international buyers?
A: GB/T3036 is a recognized standard that ensures dimensional accuracy, pressure integrity, and performance reliability. It provides a clear specification benchmark, facilitating technical evaluation and ensuring the valve meets defined quality and safety parameters, which is valued in global procurement. -
Q: What kind of after-sales support do you offer?
A: We provide technical documentation, including dimensional drawings and installation manuals. Support for installation guidance and troubleshooting is available. Spare parts like seals and gaskets are also offered to ensure long-term operability of the valve. -
Q: Are these valves suitable for food or pharmaceutical applications?
A: The standard valve is designed for industrial process use. For food, beverage, or pharmaceutical applications requiring specific hygienic standards, we can discuss options with appropriate material certifications and polished finishes upon request. -
Q: What is the warranty period for this product?
A: We offer a standard warranty against manufacturing defects. The specific warranty terms and duration are provided with the commercial contract and are based on the application conditions and valve configuration.
