JRV-SF14直動式減壓閥 韓國朝光減壓閥

■ FEATURES 1. It has an excellent endurance because of its small size and simple structure. 2. This valve can be used for the pressure regulation on the feed water from an elevated water tank of middle or high building to each floor. 3. Pressure adjusting is easy and allows ia stable control of flow. 4. The valve is designed to enable inside inspection by disassembling the upper part of valve so that maintenance is very convenient. ■ MATERIAL NO PART NAME JRV-SF14 1 Body CAST IRON 2 Bonnet CAST IRON 3 Disc SYNTHETIC RUBBER 4 Seat CAST BRONZE 5 Stem STAINLESS STEEL 6 Stem Guide CAST BRONZE 7 Diaphragm SYNTHETIC RUBBER 8 Spring CARBON STEEL 9 O-Ring SYNTHETIC RUBBER 10 Adjust Screw BRASS 11 Cap CAST IRON 12 Plug CAST BRONZE 1.INLET PRESSURE MAX 10 kgf/㎠{1.0MPa} 2.OUTLET PRESSURE 0.5~4.0, 4.0~8.0 kgf/㎠{0.05~0.4,0.4~0.8MPa} 3.MAX REDUCING RATIO 10 : 1 4.WORKING TEMP 80 ℃ 5.WORKING FLUID A.W.NL 6.CONNECION 10K RF Flange Fluid symbol 1.
