Series 65 Pressure controller Features - Fast and accurate pressure control - Automatic learning of system parameters - Hold function for plasma ignition - Valve position control - Remote control - Information display - Inputs for 1 or 2 linear pressure sensors (capacitance manometers) DeviceNet ® Pressure control - Closing or opening of the valve at power failure (option) The controller ensures fast and accurate pressure control. By operating the LEARN function — needs to be done only once at start-up — the system parameters are automatically determined. Due to the adaptive algorithm the...

Pendulum valve control system Easy maintenance - Valve need not be removed from the system for maintenance - Fast removal and reinstallation of pendulum plate and sealing ring for cleaning - Only 2 standard tools are necessary for maintenance Certain options are not available for some nominal diameters or cannot be combined. Moreover, options can affect the general technical data. Actuator / controller: - Actuator B2 (picture 1) - Controller with configurable PI parameters - RS232 interface with 2 analog outputs - Ethernet interface Valve: - Other sizes (e. g. DN 80) - Other flange types...
