Schemi di collegamento di un regolatore di pressione

In water supply systems, pressure regulators are installed 'after themselves' to reduce and stabilize water pressure, and in boiler rooms and heat supply points on automated feed lines. Regardless of the installation location, the pressure regulator connection scheme should include:

• A mesh filter
• Pressure gauges before and after the regulator at the point of connection of the impulse tube
• Shut-off valves and drain valve for preventive maintenance
• If pressure increase may cause an emergency situation, a safety valve should be installed after the pressure regulator.

The external impulse tube is connected after the pressure regulator in the direction of water flow.

Water pressure closes the valve, so with the impulse tube disconnected, the regulator will be fully open, and when connected in front of the valve (incorrectly), the regulator will shut off the flow.
