Pressure regulator, DN15 connection threads: 1/2" internal and 3/4" external on each port. Pressure gauge connection: G1/4" D04FM-1/2A

D04FM pressure regulators protect water installations against excessively high inlet pressure.
Pressure regulators are used in domestic and industrial installations, protecting them against damage resulting from pressure changes and reducing water consumption. Even with large fluctuations in inlet pressure, the outlet pressure is kept constant. By reducing and stabilizing the pressure, the flow noise in the entire system is minimized.
