General information:

The purpose of the valve is to allow unrestricted flow in one direction and restricted flow in the opposite direction. They are installed for separate services connected to the public system to avoid backflow into the pipes of each material and to prevent contamination. These valves are sometimes used to prevent a sudden rise in system pressure, so that the pressure on the low pressure equipment connected to the system is greater than its design limit.
