Reduction valves are usually installed at the inlet of a water pipeline to the consumer. The typical installation scheme of a reduction valve includes:
A strainer filter installed before the valve in the direction of water flow.
Pressure gauges before and after the valve, necessary for monitoring the quality of its operation.
Shut-off valves before and after the valve, as well as a drain valve for preventive maintenance.
If pressure increase can cause an emergency situation, a safety valve should be installed after the pressure regulator.
