2 common types of pressure control device are pressure governor and _______?

• A. Pressure relief valve
• B. Vacuum gauge
• C. Master intake gauge
• D. Flow meter

Answer: (A)

Controlling or limiting system pressure is the main idea. A pressure governor is an active regulator that keeps the pressure at a chosen level by adjusting the supply flow or pump output in response to sensed pressure. The other common pressure control device is a pressure relief valve, which acts as a safety limit by opening when pressure reaches a preset maximum and diverting fluid to prevent equipment damage. The remaining options are measurement or flow devices and don’t regulate pressure themselves, so they don’t fit as pressure control devices.
