Full Performance Oil Temperature Range 0 ° C to 70 ° C (32 ° F to 158 ° F)
Minimum temperature at -20 ° C (-4 ° F)
Temperature range from storage to -25 ° C to + 85 ° C (-13 ° F to + 185 ° F)
全性能时油液温度范围0°C至70°C (32°F至158°F)
阀性能下降时的低温度 -20°C (-4°F)
贮存时的温度范围 -25°C至+85°C (-13°F至+185°F)
除了改善机器的性能和提高寿命以外，
KB* 型比例阀通过将方向和流量组合成一
个组件(标准的 ISO 4401 安装接口)而大大地简化了系统设计。
