JRV-SF11¼õѹ·§

¡ö FEATURES Various applications for construction equipment, various types of plant equipments and freezing machine field. 1. Because this valve is a pilot direct operated type, it does not need auxiliary equipment such as an electric and a compressed air. Its capacity is larger than direct operating valve. 2. Pressure adjusting range is wide and pressure adjusting range is easy. (JRV-SF11: 0.35~8kgf/㎠{0.035 ~ 0.8MPa}. JRV-SF21: 0.35~16kgf/㎠{0.035~1.6MPa}) 3. This valve has a built-in filter and the filter prevents mal-functions of valve due to the scale and impurities and shows an excellent performance ¡ö MATERIAL NO PART NAME JRV-SF11 JRV-SF21 1 Body CAST IRON CAST CARBON STEEL 2 Top Cover CAST IRON CAST CARBON STEEL 3 Main Valve STAINLESS STEEL STAINLESS STEEL 4 Main Valve Seat STAINLESS STEEL STAINLESS STEEL 5 Piston CAST BRONZE CAST BRONZE or CAST IRON 6 Cylinder CAST BRONZE CAST ST.ST 7 Pilot Valve STAINLESS STEEL STAINLESS STEEL 8 Pilot Valve Seat STAINLESS STEEL STAINLESS STEEL 9 Diaphragm STAINLESS STEEL STAINLESS STEEL 10 Adjust Screw BRASS BRASS 11 Adjust Spring CARBON STEEL CARBON STEEL 12 Spring Case CAST IRON CAST IRON 1.INLET PRESSURE 2~10 kgf/㎠{0.2~1.0MPa} 2~20 kgf/㎠{0.2~2.0MPa} 2.OUTLET PRESSURE 0.35~1.0, 1.0~8.0 kgf/㎠ {0.035~0.1,0.1~0.8MPa} 1.0~16.0 kgf/㎠ {0.1~1.6MPa} 3.MAX REDUCING RATIO 10 : 1 10 : 1 4.WORKING TEMP Max 220 ¡æ Max 300 ¡æ 5.WORKING FLUID S S 6.CONNECION 10KFF Flanged 20KRF Flanged Fluid symbol 1.
