摘要
Actual valve stem thrust loads in a motor operated valve are monitored and measured directly by the use of load cells disposed directly between the valve and the operator. Direct measurement of stem thrust eliminates the errors associated with indirect methods. Analysis of actual thrust load measurements and correlation with other operating parameters, such as switch actuation and motor current, provides the capability to accurately calibrate valve operators and to detect valve and operator problems at an early stage.
