Providing modulating valve position control, the range of Westlock valve positioners offers electro-pneumatic and digital units to deliver reliable and effective control for both rotary and linear action valves. The K20 electro-pneumatic (analogue) positioner is the first of its kind which can be calibrated with a simple push button automatic calibration procedure, and which completes in a few minutes. The smart ICoT digital positioner has enhanced functionality with the ability to provide diagnostics on the valve and actuator, accurate measurement of all the operating parameters, and is compatible with HART communication protocol, FOUNDATION Fieldbus™ and Profibus PA™ network capability.
