进口压力表截止阀，针型阀性能参数 Performance parameter
压力表截止阀（针型阀）通常为活动管接头内螺纹连接,安装拆卸方便、连接紧固,是仪表测量管路系统中作开启或切断管路或节流作用 RETZ The pressure gauge valve (stop valve) is usually connected by the internal thread of the movable pipe joint. It is easy to install and disassemble, and the connection is tight. It is used to open or cut off the pipeline or throttle in the instrument measurement pipeline system
