when the operation engineer told you that he gives the
control valve order to open but there is no response !
what will you do ?
and if you found that there is astuck , what will you do ?
(note : it is apanumatic valve )

Answer Posted / b.kumaran
after doing all the priliminary inspection if u found the
valve is struck, u can directly give the air supply to the
actuator in a repeated manner.if the struck
is minor by repeaded giving of supply air will slowly
remove the struck.still its struck then loosen the body
bolts and try to open by the above method. If still there is
a struck up then u can remove the valve from the process
line, dismantle and clean the valve body whether any solid
material bloks the way.

you must show the examples application and give at least 4 types of transducer/sensors that can minimize the failure during the manufacturing of the resistors.
Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =
