最近,工业机械明显地趋于大型化、高速化和高精度化,这对液压装置的性能提出了严格的要求,而老式控制阀的功能已达极限。多功能阀在用作提升阀时与逻辑阀具有共性,但其基本表现形式不同。即在逻辑阀中,称作提升阀元件的零部件作为单位,而多功能阀是以具有回路功能的四通阀为单位。标准型多功能阀以新的集成系统为基础,广泛地应用于机床及工业机械,并获得好评。另一方面又增加了对多功能阀更高度集成化的 Recently, industrial machines have tended to be large-scale, high-speed and high-precision, which sets strict requirements on the performance of hydraulic devices. However, the functions of the old-fashioned control valves have reached the limit. Multi-function valves are common to logic valves when used as poppet valves, but their basic manifestations are different. That is, in a logic valve, a unit called a poppet valve element is used as a unit, and a multi-function valve is a four-way valve with a circuit function. Standard multi-function valve based on the new integrated system, widely used in machine tools and industrial machinery, and received praise. On the other hand increased the more integrated multi-function valve
