进口五阀组原理特点
进口五阀组由高、低压阀、平衡阀及两个校验（排污）阀组组成；五阀组适用于各种引进仪表装置中、与各种差压、流量、液位等变送器配套安装，工作时将两组校验阀与平衡阀关闭，如需检验时，只要将高、低压阀切断，打开平衡阀及打开两个校验阀，然后再关闭平衡阀及可对变送器进行校验和平衡即可。
The ‘Y53’ Type 5 valve manifolds are designed for direct mounting to differential pressure transmitters, with separate isolation and vent for LP and HP inlets plus equalising valve for simple calibration. Each needle valve head is designed for safe and reliable isolation, giving bubble tight shut off, with non-rotating & anti-galling tip and dynamic self-adjusting spindle seal to give long service life in a variety of service conditions.
