Often times, the end process pressure is far less than the upstream pressure. In order to protect the downstream lines, the pressure regulating station is built in order to make sure that the upstream pressure meets with the process pressure requirement.
The essential part of this system is Pressure Regulator or Control Valve. It is common that the pressure regulating station is completed with Emergency Shutdown or Shut Off System to protect the downstream process from over pressure.
If you need any specific requirement about Pressure Regulating System, please ask our representative.
