Features and applications
All articulated joints are lubricated with special grease.
Functioning principles of PVA. pneumatic clamps are the same as MVA. manual toggle clamps.
Executions PVA-APM and PVA-EPM (with magnetic cylinder), equipped with limit switches type PSW. (to be ordered separately) gives drive and/or control impulses while active.
Using a lubrication filter assembly is necessary for the cylinder to work properly for a long time, whereas flow regulators are recommended to guarantee long life of mechanical components.
