Control valve: Also called as final control element /
variable orifice (Restrictor) in a flow line.
Principle of operation : Motion Balance Principle.
Breif Description: The control valve consists of
1. Actuator (Provides power to drive the valve otion)
2. Range spring (Its the one dictates the operating range
of valve)
3. yoke (Supports the Actuator to valve boby)
4. Valve Body (where plug & Seat in there throttles the
flow according to the position between them)
** The signal provided to the actuator drives the actuator
stem which is coupled to the plug stem. this motion occurs
opposing the range spring until the resultant force
generated by the actuator and range spring nullifies.
The resultant is the travel position of the valve.

Tell me the field calibration procedure step by step with diagram of pressure gauge, pressure switch, pressure transmitter, temperature switch, level switch, flow switch, flow transmitter.
we want to control pump in let pressure and tank (for exp) our inlet line if water cam and pump will on and when our tank will full pump will off also if our inlet pressure low pump will off even tank not full.this pump i want to uses on our water supply line.
