  在选用逻辑阀时，应根据系统所需的流量，大于或等于200l/min时选用二通插装阀，小于20l/min则选用螺纹插装式逻辑阀。插装组件的阀芯有带尾部和不带尾部形式，带尾部的有缓冲和节流等作用。阀芯还有多种面积比可供选择，弹簧也有多种刚度可供选择，从而实现多种开启压力。 国内有的插装组件在阀芯和阀套之间装有O形圈，这样能确保密封，但反应速度慢。控制盖板和阀芯中的阻尼孔有多种直径，阻尼孔大反应速度快，但冲击大，阻尼孔小则反之。如果逻辑阀的动作有先后会影响系统的功能时，在选择阻尼孔的直径时，应特别慎重。控制盖板的型号很多，应根据系统情况仔细选择。 设计阀块时应画上盖板的定位孔，并标明各个油口的代号，以便装配和维修。应根据系统的流量和压力及其流量-压力曲线选型，过小往往会造成系统压力损失太大，使系统发热，若选型过大，则会使系统庞大，造成经济上的浪费。 逻辑阀有二种密封材料可选，氟橡胶密封适用于磷酸脂介质，丁腈橡胶密封适用于矿物油介质。 逻辑阀由于其高压大流量的特点特别适用于阀门快速液压驱动装置，在国内外都有成熟的逻辑阀产品，其在阀门快速液压驱动装置的应用前景是广阔的。

Application and Selection logic valve Logic in the selection valve, the system should be based on the required flow, greater than or equal to 200l/min when used two-way cartridge valves, less than 20l/min then use logic valve cartridge threads. Cartridge valve components with and without the tail with the tail form, with the tail of a buffer and reduce expenditure and so on. Spool area than there are many to choose from, there are a variety of spring stiffness to choose from, in order to achieve a variety of opening pressure. Domestic and some cartridge spool and sleeve components with O-ring between, this will ensure that the seal, but the reaction is slow. Control valve cover and a variety of orifice diameter, orifice large, fast response, but the impact of large orifice small and vice versa. If the logic valve action there has will affect the functionality of the system, the choice of orifice diameter, should be particularly careful. Control cover many models, the situation should be carefully selected according to the system. Design should be drawn on the cover of the valve block positioning holes, and indicate the code of each port, so that the assembly and maintenance. Should be based on system flow and pressure and flow rate - pressure curve selection, often too small to lose too much pressure will cause the system to make the system heat, if the selection is too large, then make large systems, resulting in economic waste. There are two kinds of logic valve seal materials available, Viton seals for phosphate medium, NBR seals for mineral oil medium. Logic because of its high-pressure high flow valve characteristics particularly suitable for fast hydraulic valve drive at home and abroad has proven logic valves, the hydraulic drive the valve fast application prospects are bright.
