As a leading manufacturer, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our premium Food Grade Processing Line Butterfly Valve, engineered to meet the rigorous demands of sanitary fluid control. Established in 2016, we have dedicated ourselves to producing high-quality industrial valves, earning the trust of clients across North America, South America, Europe, Asia, and beyond. Our commitment to excellence is underscored by our ISO9001 certification, ensuring every valve, including this GB/T3036 compliant model, delivers reliable performance, superior hygiene, and long-term value for your critical processing applications. This valve is designed to be the dependable solution for maintaining product purity and operational efficiency in your food and beverage production lines.
This butterfly valve is meticulously crafted for sanitary processing environments where contamination control is paramount. Its design and construction prioritize easy cleaning, durability, and smooth operation to minimize downtime and maintenance costs.
- Superior Hygienic Design: The valve features a smooth, crevice-free body and disc surface, preventing bacterial harborage and facilitating easy Clean-in-Place (CIP) and Sterilize-in-Place (SIP) procedures. The materials used are non-toxic and corrosion-resistant.
- Robust Construction & Materials: Manufactured from food-grade stainless steel (typically 304 or 316L), the valve body offers excellent resistance to corrosion from various cleaning agents and food products. The seat options, including EPDM, PTFE, and Silicone, are selected for their compatibility with a wide range of temperatures and media.
- Precise Flow Control & Tight Shut-off: The precision-engineered disc ensures a bubble-tight seal when closed, minimizing product loss and preventing leakage. The low-torque operation allows for easy and quick actuation, whether manually or automatically.
- Versatile Actuation Options: To suit diverse operational needs, the valve can be configured with a manual lever, a gear operator for larger sizes, or automated with pneumatic or electric actuators for integration into centralized control systems.
- Compliance & Traceability: Conforming to the GB/T3036 standard, this valve meets recognized specifications for dimensions and performance. Crucially, a comprehensive Mill Test Report (MTR) is provided with each batch, offering full material traceability and verification of chemical composition and mechanical properties, a critical requirement for quality assurance in regulated industries.

Frequently Asked Questions (FAQ)
-
Q: What does "Food Grade" specifically mean for this butterfly valve?
A: "Food Grade" indicates that all wetted parts (body, disc, seat, seal) are made from materials approved for contact with food and beverages. They are non-toxic, corrosion-resistant, and designed with smooth surfaces to prevent bacterial growth, making the valve suitable for sanitary processing lines. -
Q: Is the GB/T3036 standard compatible with international standards like ISO or ANSI?
A: While GB/T3036 is a Chinese national standard, its dimensional and performance specifications for wafer and lug-type butterfly valves are often aligned with common international practices. Key dimensions like face-to-face length and flange drilling can be compatible with ISO and ANSI standards, but specific requirements should be confirmed during inquiry. -
Q: Why is a Mill Test Report (MTR) important?
A: An MTR is a certified document from the material mill that verifies the chemical composition and mechanical properties (like tensile strength) of the raw stainless steel used. It provides traceability and proof that the material meets the specified grades (e.g., 304, 316L), which is crucial for quality control, safety, and regulatory compliance in food and pharmaceutical industries. -
Q: Can this valve handle CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes?
A: Yes, it is designed for such processes. The selection of appropriate seat material (like EPDM or PTFE) is key, as it must withstand the high temperatures and aggressive chemicals used during CIP/SIP cycles without degrading. -
Q: What actuation methods are available?
A: The valve is highly versatile. It is available with a standard manual lever for simple on/off control, a gear operator for easier handling of larger valve sizes, and can be fitted with pneumatic or electric actuators for automated, remote operation within a processing control system. -
Q: What is the typical delivery lead time for an order?
A: Lead time varies based on order quantity, valve size, and actuation type. Standard configurations often have shorter lead times. We recommend contacting our sales team with your specific needs for an accurate delivery schedule. -
Q: Do you offer customization for special requirements?
A: Yes, we can discuss customization options such as specific surface finishes (e.g., Ra ≤ 0.8µm for higher hygiene), special seat materials, different connection standards, or the integration of specific actuators. Please provide your detailed specifications for a tailored solution. -
Q: What are your main export markets and shipping terms?
A: We export globally, with significant experience in North America, South America, Eastern Europe, Southeast Asia, Africa, and Oceania. We ship from ports in Shanghai, Guangzhou, Hong Kong, and Beijing, and can work under standard international trade terms like FOB, CIF, or CFR based on mutual agreement.
