The valve uses 316L stainless steel for product-contact components and can be supplied with precision mechanical polishing or electropolishing to achieve a smooth internal surface. The crevice-minimized flow path helps reduce product retention and supports easier cleaning during routine production and CIP/SIP procedures.
For automated process lines, the Sanitary 316 Pneumatic Wafer Butterfly Valve can be configured with a pneumatic actuator, while manual operating options are also available. Different seat materials and actuation configurations allow the valve to be selected according to the media, temperature, cleaning method, and control requirements of the application.
The wafer configuration is positioned between two pipeline flanges without requiring a long valve body, helping reduce the overall installation footprint. This structure is particularly useful for sanitary skids, processing equipment, and piping systems where available space is limited. The compact construction also makes removal and maintenance more convenient.
The wetted components are manufactured from SS304 or SS316L stainless steel, with 316L being particularly suitable for applications requiring higher corrosion resistance and stringent hygienic requirements. The material selection can be matched to the process medium and operating environment.
Product-contact surfaces can be precision mechanically polished or electropolished, with a surface finish of Ra ≤ 0.4 μm available. A smoother internal surface reduces areas where process residue can accumulate and supports more effective cleaning during production changeovers.
The Sanitary 316 Pneumatic Wafer Butterfly Valve is designed for hygienic processing systems that use CIP (Clean-in-Place) and SIP (Sterilize-in-Place) procedures. Its crevice-minimized internal structure helps limit product retention and supports cleaning and sterilization without frequent valve disassembly.
AVM provides pneumatic actuation for applications requiring remote or automated valve operation. The actuator can be integrated with process control systems to control pipeline isolation or flow adjustment according to the production sequence.
In addition to pneumatic operation, the valve can be configured with a manual pull handle, multi-position handle, gear operator, or electric actuator. This allows the same basic valve platform to be adapted to local manual systems as well as automated sanitary production lines.
The valve can be supplied with EPDM, Silicone, FKM (Viton), or PTFE seat materials. Different sealing materials provide different levels of resistance to temperature, chemicals, and process media, allowing buyers to select a suitable configuration according to the actual operating conditions.
The resilient seat structure provides reliable bi-directional sealing with low leakage. The available concentric or double-eccentric disc configurations can be selected according to the required operating characteristics and torque requirements of the sanitary pipeline.
The streamlined disc design helps reduce flow resistance while maintaining effective pipeline isolation and flow control. This makes the valve suitable for liquid transfer systems where pressure loss and flow efficiency need to be considered during valve selection.
The modular valve construction allows sealing components to be replaced when required, helping reduce maintenance downtime. This is particularly useful in processing facilities where valves are operated frequently or exposed to repeated cleaning cycles.
The valve can be used in breweries, dairy plants, beverage production, juice processing, bottled water systems, syrup handling, and food processing lines for pipeline isolation and flow control.
The Sanitary 316 Pneumatic Wafer Butterfly Valve is suitable for purified water systems, Water for Injection (WFI) systems, fermentation equipment, formulation lines, aseptic processing, and CIP/SIP pipelines where cleanability, corrosion resistance, and process hygiene are important.
For cosmetic processing systems, the valve can handle applications involving lotions, creams, perfumes, shampoos, and other liquid ingredients where hygienic fluid transfer and contamination control are required.
The 316L stainless steel construction and multiple seat options make the valve suitable for high-purity chemicals, additives, specialty liquids, and other process media requiring corrosion-resistant and hygienic flow-control equipment.
The sanitary wafer butterfly valve can be integrated into different hygienic pipeline configurations according to the selected connection arrangement and system design. Its compact wafer structure is especially suitable for processing equipment where installation length needs to be minimized.
Manual pull handles and multi-position handles are suitable for local operation, while gear operators can be used where additional manual operating torque is required. Pneumatic and electric actuators provide options for automated production lines and centralized process control.
AVM focuses on the practical requirements of hygienic valve applications, including installation space, surface cleanliness, sealing material selection, cleaning procedures, and automation. The wafer structure helps simplify installation in compact piping systems, while 316L stainless steel and polished product-contact surfaces support demanding sanitary applications. With multiple seat and actuator options, the valve can be configured for different media and process-control requirements.
