Valves 6600 SERIES 2412 SERIES 2203 SERIES 2600 SERIES 2412M SERIES 2900 SERIES 6801 SERIES Pressure Regulating Valve MODEL 6600 SERIES It is the light-weight and compact precise-pressure control valve having superior reproducibility. It enables sure and rapid pressure control with high accuracy. Since the inside of the valve has been rinsed completely with the super-cleaning method, it should be optimum product as a high-sensitivity analysis device or for research and development. Features Control characteristics with high accuracy It provides high control performance of reproducibility ± 1% for primary pressure fluctuation and secondary load resistance fluctuation. Optimum for panel installation Since the inlet and outlet for liquid are installed at the back of the body, pipes can be easily laid. And it is optimum for panel installation because of its light-weight and compact size. Non-bleed type It is a non-bleed type and has passed strict leakage tests. Application For gas chromatograph For chemical measurement instruments Gas Blender Standard specifications Primary maximum pressure 784KPa Secondary control pressure A type: 9.8 to 294KPa B type: 29.4 to 588KPa Minimum operating pressure 49KPa Pressure resistance 784KPa Reproducibility within ± 1% for rated pressure Elapsed change within ± 1.5% for rated pressure Temperature characteristics within ± 1% for rated pressure Temperature resistance Aluminum body: 60°C SUS body: 120°C Flow rating See rating graph (P143) Connection opening Rc1/8 Rc1/4 Materials of liquid contact parts (A) aluminum, brass, NBR, Polyacetal (SS) SUS316, Viton, fluorine resin
