A flow control valve controls the flow rate based on the change of resistance of the flow channel using a needle to adjust the opening of the flow channel that functions as a small orifice

The possible uses of the pressure control valve are widely varied and well established. It can be used in two possible ways depending on the application:

The flow control valve as the name implies is used to precisely regulate flow through it. This is achieved by having a variable flow area from zero to full opening.

A rising pressure level leads to opening of the valve while comfortable pressure level is denoted by closed control valve.

A subsea control valve (sometimes known as a subsea choke) is as the name suggests, similar to a common land based control valve, expect its application is based in underwater environments. The severe service environment can either be on the seabed or below the seabed
