A Pressure Relief Valve is used to protect the refrigerant compressor unit from excessive pressure buildup. When the pressure inside the refrigerant compressor reaches or exceeds the set pressure of the relief valve, the valve opens to allow the refrigerant to escape. By relieving the excess pressure, the valve helps prevent damage to the compressor unit parts.Attributes:• Opening pressure of 3450 - 3920 kPa in a pressure relief valve indicates the range at which the valve will start to open and relieve pressure in a unit• Helps to maintain stability by preventing pressure fluctuations and surges Applications:A Pressure Relief Valve acts as a safety mechanism to prevent overpressure and protect the integrity of the refrigerant compressor unit, ensuring reliable and safe operation under varying conditions.
