Series 6223 servo-assisted, solenoid-operated proportional valves feature good control response and low hysteresis. The mechanical construction in the form of a servo-assisted valve makes it possible to implement large nominal diameters or high flow values with low electrical drive power values.
In addition to the servo-assisted proportional valves, direct-acting proportional valves offer a broad application scope for dealing with low flow rates, high pressures, fast control response or low overall volume.
Use of the compact temperature controller type 8625 integrated directly in the connector socket produces a high performance control system. The controller is mounted directly on the proportional valve and an RTD temperature sensor is connected directly to the controller. Set-point presetting is performed using the keypad/ display or externally by means of 4-20mA.
Along with the temperature controller, this series of controllers comprises corresponding devices for control of pressure and flow rate.
