PRD pressure relief valve

PRD (Pressure Relief Damper) pressure relief valve is a device used to control and maintain pressure in ventilation and air conditioning (HVAC) systems. When the pressure in the duct or space exceeds the set value, the valve will automatically open to release air, helping to balance the pressure and protect the system. When the pressure returns to a safe level, the valve will automatically close, ensuring stable and efficient operation.

PRD valves are used in HVAC systems, clean rooms, technical rooms, pressurized elevator chambers and areas requiring pressure control, helping to maintain stable pressure stable and safe.
