What must be done to reduce the pressure in a system that uses utility street steam?

1. Install a drain

2. Utilize a Pressure Reducing Valve (PRV)

3. Increase the steam flow rate

4. Use a temperature stabilizer

The correct answer is: Utilize a Pressure Reducing Valve (PRV)

Using a Pressure Reducing Valve (PRV) is the essential method for controlling and reducing the pressure in a system that employs utility street steam. A PRV is specifically designed to maintain a desired pressure level by automatically adjusting the flow of steam. When high-pressure steam enters the control valve, the PRV reduces it to a much lower pressure for use in the system, ensuring that equipment operates safely and effectively within its designed parameters. This is crucial for preventing damage that could occur from excessive pressure and for regulating the supply of steam needed for heating or processes. In contrast, while draining excess water may assist in managing system pressure indirectly, it does not actively control or reduce the steam pressure. Increasing the steam flow rate could inadvertently raise the pressure, which is counterproductive. A temperature stabilizer primarily regulates temperature rather than pressure, and would not effectively address the need to reduce steam pressure in the system.
