Vapor Pressure Controller - DigiVac VPC-vacuum regulator

Description The DigiVac Vapor Pressure Controller allows you to determine set-points and maintain vacuum at that level.The vacuum regulator is particularly useful when you are looking to maintain pressure at a certain level as needed for botanical processing and rotary evaporation.Mounting can be bench-top or on a laboratory pole.Valve control - pfeiffer-vacuumThe required control pressure is often in the range 0.4 to 0.8 MPa.A pneumatic cylinder transmits its movement to the valve plate.If a direction is operated by compressed air and the opposite direction reset with a spring,the drive is called single acting pneumatic.Vacuum unit pressure control - DigitalRefiningPressure control Many vacuum units have no pressure control.Thus,the first-stage ejector load sets the flash zone operating pressure.A higher ejector gas load increases the operating pressure,while a lower gas load decreases the operating pressure.However,pressure control is necessary in some cases to intentionally avoid low pressure or to raise the column operating
