The direct-acting proportional valve Type 2833can be used as a control valve for process control and is suitable for technical vacuum. Low hysteresis, high repeatability and high sensitivityensure superior regulation behaviour. Thanksto an elastomeric sealing, the valve closestightly and securely.Valve control takes place through the controlelectronics of Type 8605, which converts ananalogue input signal into a PWM signal2).Further, functional features of the Type 8605 electronic control unit:

• Temperature compensation for coil heatingby internal current regulation

• Simple zero and span settings

• Ramp function to dampen fast statuschanges
