CVR 直落式旋转阀
用于重力卸料和真空上料的标准直落式气锁阀。
The CVR is the standard drop-through airlock: product falls by gravity into the rotor pocket and is discharged at the bottom, which suits gravity discharge under a silo, a vacuum receiver or a dust hopper.
The body is a single casting machined on both faces. The rotor can be open or closed, with adjustable tips that bring the gap back to 0.10 mm when the body wears. Outboard bearings keep the grease away from the product path.
Options include air-purge shaft sealing, a bronze-tipped rotor for fine combustible dust, replaceable wear plates for mildly abrasive product, and flange drilling to DIN PN10, ANSI 150# or JIS 10K.
