升降机液压系统离不开液压阀的存在，质量优良的液压阀可以使升降机的液压系统的设计更合理、性能更优良、安装更简便。在选择液压阀时都应该考虑其额定的压力，同时还要考虑流量、安装形式以及经济性等方面的因素。

升降机液压系统的压力阀是用于控制液压系统的重要器件，大家可以根据液压系统的工作压力以及压力的实际需求来选取合适的控制阀。在实际的生产过程中，为了防止系统过载，大家可以选择在升降机泵站的出口再并联一下安全阀，这样就可以保持整个系统的安全。总之，大家在选择液压系统的液压阀时一定要从安全的角度出发，确保生产安全，这才是选择的核心所在。
Elevator manufacturers are talking about the hydraulic system pressure valve is used to control the important components of the hydraulic system, we can according to the working pressure of the hydraulic system and the actual demand of the pressure to select the appropriate control valve. In the actual production process, in order to prevent the system overload, we can choose in the lift pump station exit and then parallel the safety valve, so that you can maintain the safety of the entire system. In short, everyone in the choice of hydraulic system of hydraulic valve must be from a safety point of view, to ensure the safety of production, this is the core of choice. 

在选择升降机液压阀之前，企业应该根据系统的功能要求确定液压阀的类型，然后再根据实际情况选择合理的升降平台的液压阀连接方式，也可以是管式连接，也可以是板式连接。根据升降平台液压系统所设计的最高工作压力来确定液压阀的额定压力，然后再根据液压阀的最大流量来确定企业所需要的液压阀的流量规格。
Analysis of elevator manufacturers before hydraulic lifter valve selection, the enterprise should determine the type of hydraulic valve according to the demand of the function of the system, then according to the actual situation choose reasonable lifting platform of hydraulic valve connection mode, can also be a tubular connection can also be is the type of connection. According to the lifting platform hydraulic system designed to determine the maximum working pressure of the hydraulic valve rated pressure, and then according to the maximum flow of hydraulic valves to determine the required hydraulic valve flow specifications.
