Pressure reducing valves (PRVs)
Pressure-reducing valves (PRVs) are a type of flow control valve designed to maintain a specific pressure on the downstream side of the valve, regardless of variations in upstream pressure. These valves are crucial in various applications where consistent and controlled pressure is required. Pressure reducing valves are essential for preventing damage to downstream equipment, ensuring system safety, and optimizing the performance of various processes that require a specific pressure range.
Key Components and Working Mechanism:
Main Valve Body:
The main valve body contains the components that control the flow of fluid through the valve.
Pilot Valve:
The pilot valve is a smaller valve connected to the downstream side of the main valve. It senses the downstream pressure and controls the opening and closing of the main valve.
Adjustment Spring:
The adjustment spring is a component that exerts force on the pilot valve. By adjusting the tension of the spring, the setpoint for the downstream pressure can be controlled.
