Special pressure regulator, pressure reducer and pressure transducer type valves through which the pressure in the refrigeration installation is regulated and correctly identified in order to protect the HVAC system ...from inadequate pressure levels. The pressure regulators, respectively, the pressure reducers protect the systems especially in case of too high pressures. The pressure transducers identify the force with which the refrigerant exerts pressure on the pipe walls, having an important preventive role. Mai mult
