Preset or Batch Control Valves
The Preset or Batch Control Valve shall be a Digital Control Valve which is hydraulically-operated, diaphragm-controlled valves, typically used in conjunction with a Batch or Preset Controller. The Preset Valves have got two solenoid controls. The normally-open (N.O.) and normally-closed (N.C.) solenoids, located in the upstream and downstream portions of the control loop, respectively, control the operation of the valve. With both solenoids energized, high upstream pressure is blocked allowing the product in the cover to vent to low downstream pressure, opening the main valve. Conversely, de-energizing both solenoids allows high upstream pressure to close the valve.
