Where are shutoff valves located on a Pressure Reducing Valve (PRV)?

After the PRV only
Before the PRV only
Both before and after the PRV
On the main supply line

The correct answer is: Both before and after the PRV

The shutoff valves on a Pressure Reducing Valve (PRV) are typically located both before and after the PRV. This configuration allows operators to isolate the PRV from the system for maintenance or repair without disrupting the entire supply line. By having shutoff valves installed on both sides of the PRV, technicians can safely service the valve while preventing the flow of water or steam through it, which is essential for ensuring safety in the operation of low pressure boilers. Isolating the PRV in this manner also allows for any necessary adjustments or replacements without affecting other connected systems. Therefore, the presence of shutoff valves both before and after the PRV enhances overall system functionality and safety, making it the correct answer.
