Perfection has arrived! The NFPA-compliant rotary valve airlock, which is equipped with a hardened tool steel knife, has combined the shearing features of a rotary feeder, with the heavy-duty robust nature of a rotary valve creating what we believe to be the PERFECT rotary valve airlock!
Manufactured from a through-hardened, abrasion-resistant, 500 Brinell steel alloy, which is surface-treated to push the hardness rating to nearly 60 Rockwell. The knife-equipped rotary valve airlock is unlike any comparable product available in the market today!
NFPA Compliant, Shearing Capabilities, Heavy-Duty Construction! The Perfect Airlock!
