As a professional manufacturer with a commitment to precision and hygiene, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Low-Torque Pneumatic Butterfly Valve designed specifically for Clean-In-Place (CIP) systems. Engineered to meet the stringent demands of modern hygienic processing, this valve combines the efficiency of pneumatic actuation with a low-torque disc design, ensuring reliable and gentle operation that protects sensitive process lines. Built to DIN 3202 standards, it offers seamless integration into global food, beverage, pharmaceutical, and biotech installations, providing a robust solution for automated flow control where cleanliness and reliability are non-negotiable.
Our valve is engineered to deliver superior performance in demanding hygienic environments. Its core advantages stem from a thoughtful design focused on operational efficiency and sanitary integrity.
Key Features & Technical Advantages:
- Optimized Low-Torque Design: The specially engineered disc and stem configuration significantly reduces the operating torque required. This translates to smaller, more cost-effective pneumatic actuators, lower air consumption, and reduced wear on valve components, leading to extended service life and lower total cost of ownership.
- Superior Hygienic Performance for CIP: The valve features a smooth, crevice-free body interior and a flush-mounted disc when in the closed position. This design minimizes product entrapment and allows cleaning and sterilizing agents to flow freely during CIP cycles, ensuring thorough sanitation and preventing bacterial harborage points.
- Pneumatic Actuation for Automation: Equipped with a double-acting or spring-return pneumatic actuator, the valve enables fast, precise, and repeatable open/close cycles. This is essential for automated process control, allowing for remote operation and integration into PLC-controlled systems, enhancing production line efficiency.
- Robust Construction & Material Compliance: The valve body is typically constructed from polished stainless steel (304 or 316L), while the seat is made from food-grade elastomers like EPDM or PTFE. These materials offer excellent corrosion resistance, durability, and compliance with food contact regulations.
- DIN 3202 Standard Compliance: Manufactured according to DIN 3202 F4/F5 standards for wafer and lug type butterfly valves, ensuring dimensional interchangeability, reliable sealing performance, and easy installation within European and internationally recognized piping systems.

Frequently Asked Questions (FAQ):
Q1: What makes this valve "low-torque," and why is it beneficial?
A: The "low-torque" feature is achieved through an optimized disc profile and bearing design, which reduces friction during rotation. The primary benefit is that it allows the use of a smaller, less expensive pneumatic actuator to operate the valve, leading to lower initial costs, reduced compressed air consumption, and less mechanical stress for longer valve life.
Q2: Is this valve suitable for Steam-In-Place (SIP) sterilization as well as CIP?
A: Yes, when configured with appropriate high-temperature seat materials like PTFE or specific EPDM grades, this valve can be designed to withstand SIP cycles. Please specify your required temperature and pressure conditions during inquiry.
Q3: What are the main differences between wafer and lug connection types for this valve?
A> A wafer-style valve is sandwiched between two pipeline flanges and is suitable for systems where the pipeline supports the valve. A lug-style valve has threaded inserts (lugs) on both sides, allowing it to be bolted directly to each flange, which is advantageous for end-of-line applications or where pipeline support is limited.
Q4: Can you provide valves with position feedback or proportional control?
A: Yes. We can equip the pneumatic actuator with limit switches for open/close position feedback or an electro-pneumatic positioner for precise proportional flow control (modulating service). Please indicate your control requirements.
Q5: What is the typical lead time for an order?
A: Lead time depends on the order quantity and specific configuration. For standard sizes and materials, we often have stock or short production cycles. We provide accurate lead time estimates with every quotation.
Q6: Do you offer material certificates and test reports?
A> As an ISO9001-certified manufacturer, we can provide standard material certificates (e.g., 3.1 for metallic components). Additional testing reports, such as for pressure or leakage, are available upon request.
Q7: Are custom configurations, like special stem extensions or different surface finishes, possible?
A: Absolutely. We offer a range of customization options, including extended stems for insulated lines, special Ra surface finishes for enhanced cleanability, and various seat and seal materials to suit specific media.
Q8: How do you ensure the valve's performance meets the claimed specifications?
A: Our manufacturing follows strict quality control protocols under the ISO9001 framework. Valves undergo functional testing, including seat leakage tests and operational torque checks, to verify they meet the declared performance standards before shipment.
