Sanitary Pneumatic Butterfly Valves - Overview, Material & Technical Specifications

Sanitary pneumatic butterfly valves adopt a new type of pneumatic actuator, including double-acting type and single-acting type (spring return), with gear transmission for safety and reliability. Standard electro-polished smooth surface ensures cleanliness, free of medium accumulation areas and no potential contamination. The quick disassembly and assembly structure enables fast and easy valve opening and maintenance, shortening process downtime effectively.
