PRV

Pressure / Vacuum control valves, commonly known as PRVs, are essential for safeguarding containers during the loading and unloading phases of powder, grain, and fiber products. These control valves are crucial in maintaining the safety and integrity of containers by managing the internal pressure levels.

A PRV operates as a relief valve to control or limit the pressure within a system. This is especially important when excessive pressure may lead to process upsets, equipment failures, or even fires. The valve is set to open at a predetermined set pressure, ensuring that it relieves pressure by allowing the pressurized fluid to flow into an auxiliary passage and out of the system. This safeguards pressure vessels and other critical equipment from pressures that exceed their designed thresholds.
