Why flow/pressure transmitter before control valve?
components of control circuit belongs to control valve
Q- What are the application in which PNP transistor is preferred over NPN ?
If a control valve is hunting means means if we are giving 50% to the cv, the cv will open at 51% then slowly slwoly it will reaches 49% , so what to do for solve this problem. The cv is double acting and mounted for anti surge operation, it having 4 nos. volume booster, one sov, one positioner, etc..?
