The functions of control valves in different positions

What is the role of a liquid control valve in the circuit piping? What is the role of the gas control valve in the inlet pipeline?

The control valve for the liquid is located in the circuit pipeline, usually at the pump outlet, in order to ensure a minimum flow rate and prevent the pump from getting stuck； The second reason is to maintain the liquid level in the tanks ahead. The control valve for the gas is located on the inlet pipeline; there are two possibilities: either to maintain a stable gas flow rate, or to keep the pressure downstream stable and prevent overpressure.
