The advantages of Trevitest For routine inspection: 对于正常检验而言 Eliminates the need to shut down the process避免系统停车 Valve re-certification on-line (set pressure verification)阀门的设定压力调整可在线进行 Eliminates the need for temperature compensation由于在正常操作温度下进行实验，不需要温度补偿调整压力 Enables valves to be aligned to delayed outages Enables longer periods between outages to be planned For corrective action:对于校正活动而言 Testing valve for operational readiness测试阀门为系统运行做准备 Measuring valve lift可以测试阀门的起跳 Provide good i
