High Pressure Safety Valve HVAC: Description and Operation
Pressure Relief Valve
The pressure relief valve is integrated with compressor. At pressures above 40 bar (580 psi), the pressure relief valve opens to air outlet excessive
pressure. When the system pressure is reduced, the valve closes to prevent total refrigerant loss.
