This plumbing detail shows an inline pressure reducing valve assembly equipped with isolation valves typically positioned at both ends. A strainer precedes the pressure-reducing valve to capture upstream debris. Pressure gauges and Pete's plugs are installed on both sides to monitor operating pressures, accompanied by a thermometer for temperature measurement. A temperature and pressure safety valve rated for ninety pounds per square inch maximum is located downstream.
