Based on the risk being protected appropriate section valves are selected. These can be located close to the pump station or adjacent to the area to be protected. These are not to be located within the protected area.
Typically, a section valve set features inlet and outlet pipes, manual or actuated isolation section valve, manual ball valve after the main section valve for maintenance and testing purposes and a test/drain valve. A pressure gauge is provided for monitoring the pressure and a flow sensor is used to monitor flow.
