1R Proportional Material Regulator

The Autostream 1R system includes a proportional material regulator as a pressure control device.

The output pressure of this pneumatically operated valve is adjusted by changing the control air pressure applied to it. The changes can be achieved by manual adjustment of the air pressure, or by changing the strength of the electronic flow rate signal ( 0 to 10v DC or 0 to 4095 Dnet ). The 1R system can dispense from 5cc to 55 gallons of material in one job.
