Control handle for remote activation and deactivation of an abrasive blast machine. Fail-to-safe system stops blasting if operator drops or loses control of the handle. For use with Clemco remote control systems only.
Pressing the remote control handle activates the system and starts blasting; releasing the handle stops blasting. When the handle is released, a spring-loaded lever mechanism keeps the handle from accidentally activating the system. The pneumatic handle utilizes twinline hose (both sides of the twinline are 3/16" ID). Air travels out one side of the twinline hose and escapes from an orifice in the handle. When the handle is pressed, a rubber button blocks the orifice, diverting the air back along the other side of the twinline hose. The returning air activates the remote control valves to begin blasting.
