PDV

Extremely rugged unit with a fully retractable clamp jaw

Diagram

The PDV's retractable jaw allows dies to be raised and moved past the clamp without clearance limitations. The jaw's movements and clamping take place automatically in series. Only two hydraulic lines are necessary, one to clamp and one to unclamp. If clamping heights are varied the PDV-VSB version can be ordered to accept tolerances of ± .020".
