The AVM Sanitary Pneumatic Butterfly Valve with Limit Switch Box combines a sanitary butterfly valve structure with pneumatic actuation and electrical position monitoring. The integrated limit switch box provides real-time OPEN/CLOSED feedback signals to PLC, DCS or control systems, allowing operators to monitor valve status and achieve automated process management.
Manufactured with hygienic stainless steel materials and FDA-compliant sealing components, the valve features smooth internal surfaces, reliable sealing performance and compatibility with CIP cleaning processes. AVM products are manufactured under ISO 9001 quality management systems and meet international requirements including 3-A Sanitary Standards, CE and FDA compliance.

knowing the valve position is as important as controlling the valve itself. A valve without feedback may cause uncertainty during filling, mixing, transfer or CIP processes.
The AVM Sanitary Pneumatic Butterfly Valve with Limit Switch Box uses a position detection system installed on the actuator mechanism. When the valve reaches fully open or fully closed positions, the limit switch box sends corresponding signals to the control system.
The feedback function helps operators achieve real-time monitoring, process interlocking and equipment status confirmation. It is especially suitable for production lines requiring automatic sequencing, multiple valve coordination and centralized control.
By integrating valve operation and position feedback into one system, manufacturers can reduce manual inspection requirements and improve process consistency.
valve design directly affects cleaning efficiency and product safety. Internal dead spaces, rough surfaces or unsuitable sealing materials may increase contamination risks.
AVM sanitary butterfly valves use precision-machined stainless steel bodies with smooth internal flow paths to reduce material retention. The compact structure minimizes maintenance requirements while supporting hygienic operation in demanding environments.
The valve structure is suitable for cleaning-in-place processes, allowing production equipment to be cleaned without frequent disassembly. This helps reduce downtime and improves production efficiency in continuous manufacturing systems.
The smooth surface finish and sanitary sealing design help prevent residue accumulation during fluid transfer, supporting strict hygiene requirements.
AVM provides flexible actuation configurations according to automation level, installation conditions and customer requirements.
The pneumatic actuator provides fast response and repeatable operation, making it suitable for automated pipelines. Normally Open (NO), Normally Closed (NC) and Air-to-Air (A/A) configurations are available according to process requirements.
The pneumatic design allows frequent valve operation while maintaining stable performance in automated production lines.
For simple pipeline control, manual handles including pull handles, multi-position plastic handles and stainless steel handles can be selected.
Electric actuators are also available for systems requiring electrical control integration and centralized automation management.
Therefore, different material combinations and connection designs are available.
The valve body can be manufactured from SUS304 or SUS316L stainless steel, providing excellent corrosion resistance and long service life in hygienic environments.
Sealing materials including silicone, EPDM and FKM are available with FDA-compliant options for different working conditions.
Connection types include welded, clamp, threaded, flange and union designs, allowing easy integration into existing sanitary pipelines.
