Pressure 800kPa Set Pressure 100-600kPa CL523: Lock Valves Used for shut off, switching, or locking of instrumental air circuit ( air relay) .Used for shut off, switching, or locking of instrumental air circuit ( air relay) . Max. Pressure 800kPa Set Pressure 100-600kPa PRF300: Airfilter-Regulator For regulating instrument air. Max. Set Press 200/ 400/ 800kPa Air Connection Rc 1/ 4, 1/ 4NPT PRF400: Airfilter-Regulator For regulating instrument air. Max. Set Press 200/ 400/ 800kPa Air Connection Rc 1/ 4, 1/ 4NPT PP800: Pneumatic-Pneumatic Positioner Same series as EP800 but this works having pneumatic signal ( 20 to 100Kpa) . Also double acting and single acting types are available. EP800: Electro-Pneumatic Positioner EPA800 for single acting EPC800 for double acting EPB800 for 5200LA actuator EP1000: Electro-Pneumatic Positioner This is an intelligent electropneumatic positioner that conforms to field equipment communication standard HART, which is a world standard. It permits easy and positive digital adjustment of positioner response characteristics and zero and span from a host equipment mounting DDL or from an HHC ( Hand Held Communicator) . Furthermore, with 3-key calibration executed by a pushbutton built in the positioner, it is possible to set principal items by unit positioner, without need for HHC or the like. It can be mounted to an actuator of any of single action type, double action type, rotary type and linear type, and it operates with a 4-20mA instrumentation signal and compressed air. Therefore, it is a positioner of broad universality, and it is capable of transmitting self-diagnosis information and others besides valve opening and open/ close limit signals to a host equipment that conforms to HART. KOSO is now developing FF dealing equipment, which digitalizes up to control signals and conforms to Fieldbus Foundation Standards. control valve
