Description
This range of control valves can be used in air conditioning systems to control the flow of chilled and heating water, condensor water or low temperature steam. For suitable actuators please refer to the relevant SM literature for Regulator Servo Motors. The valves are screwed and available in sizes from 15mm to 40mm with Kv values of 6.3 thru 40.
