It is designed to use to convert flow rate fluids and/or keep available temperature and/or control the capacity of fluid in system. Also the trim part is designed proportion control case type. So it is proportion control valve. The actuator part use "Pneumatic Diaphragm type" so the actuator is great in ability of control the valve. ● FEATURE 1) Precision control is possible 2) Emergency operating is possible with emergency handle devices. 3) It is not influenced by change of differential pressure because it is balance type. 4) It can manufacture and/or supply the trim part as the specific of control. 5) The stellite processing on the Trim part makes a valve strongly. ● Specification Model K2C-DP Type Pneumatic Diaphragm Applicable Fluids Steam, Water, Oil Applicable Press. / Temp 20 kgf /㎠      /      220℃ Material Body Ductile Cast lron, Bronze, Cast Steel Trim Stainless Steel Flow characteristics Equal Percentage, Linear, Quick Opening Rangeability 30 : 1      /      50 : 1 Size 15 ~ 350 mm Operating Pressure 0.2~1.0 kgf /㎠      /      0.4~2.0 kgf /㎠ Accessories(Option) ● Controller(E/P, P/P)     ● Positioner(E/P, P/P)           ● Sensor(Pr.,, Temp.)     ●   Air set                                    ● Dimensions (mm) Size mm(inch) d L D1 D2 H1 H2 G Weight (Kg) 15(1/2") 15 136 271 160 372 172 58 17 20(3/4") 20 140 271 160 372 172 58 19 25(1") 25 150 271 160 384 172 63 21 32(1 1/4") 32 190 271 160 417 172 79 27 40(1 1/2") 40 190 271 160 417 172 79 39 50(2") 50 222 355 200 512 195 106 48 65(2 1/2") 65 290 355 200 514 195 123 65 80(3") 80 310 355 200 546 195 141 78 100(4") 100 350 465 200 676 195 162 110 125(5") 125 390 465 200 683 195 176 150 150(6") 150 451 465 200 731 195 213 185 200(8") 200 543 520 280 895 303 253 232 250(10") 250 688 520 280 925 303 270 270 300(12") 300 737 520 280 960 303 290 350 350(14") 350 889 520 315 1050 345 320 410
