Pressure controlled valves 290 ASCO

2-way, 1/2 "-2 1/2", normally closed / open, for pressure difference 0-16 bar

Features:

  • •Precise, quick-acting and robust valve suitable for

use in outside industrial environments

  • Exceptional long service life
  • Variable flow proportional to the control signal
  • Real-time control
  • Ready-to-use valve
  • The positioner can be directly connected to an
  • external sensor (double loop control)
  • Power saving function and no air consumption when
  • position is reached
  • Manual valve operator
  • LED indicators for valve status display
