ASCO 614 Series SentronicPLUS Proportional Valve

Brand: ASCO

ASCO 614 Series SentronicPLUS is a 3-way digitally operated pressure regulator valve that accurately adjusts pressure, flow, force, speed, and linear or angular positions to control air and inert gas media.

Its construction allows use in potentially explosive atmospheres according to ATEX Directive 2014/34/EU.

The valve´s components are designed to provide control at an extremely low hysteresis. Valve control loop parameters are easily configured and optimized for specific customer requirements using ASCO Data Acquisition Software (DaS) and a PC connection.
  • Orifices have the same diameter for short response times whether increasing or exhausting pressure.
  • Intelligent digital communication enables simple operation.
  • Dual-loop control allows easy configuration of process variables such as flow, force, speed, RPM, and temperature.
  • Integrated visual display permits easy monitoring of valve status.
  • DaS software allows selection of personalized settings to optimize control loop performance.
  • Vacuum service and high-pressure (725 psi) versions are available.
