The function of the pressure controller is to obtain the depressurization of fluid of the 200 Atm. whereupon Atm is accumulated in the cylinder to a pressure of exit between 0.3 to 0.5. With this value it enters the admission manifold.
It must also assure the closing and liberation of gas, according to is corresponding electrovalve. In case of faults while depressurization of gas, its safety valve will activate between 10 to 12 atmospheres.
It allows the regulation system to work in a progressive way, allowing therefore the metering required in each case. To assure that the circuits gas/water stay watertight among them and with the outside.
The regulator has a heating circuit that holds a concealed knife with the circuit of refrigeration of the motor (to see pipes and connections of water)
