Tilleggsinformasjon - Ventable, pilot-betjent, balanced-poppet relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the ventil setting, the ventil starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-veis valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
