VALVE R12/R134A 18MM

Valves are an essential component of vehicle air conditioning systems, where they play an important role in controlling the flow of refrigerant, ensuring that the system operates efficiently and energy-savingly. They include globe valves, control valves and safety valves, each of which has a specific function: globe valves control the amount of refrigerant flowing into the evaporator; control valves adjust the pressure differential between different parts of the system; while safety valves ensure that the pressure is released in the event of overpressure in the system. Regular inspection and maintenance of the valves is crucial for the optimal operation of the air conditioning system and the comfort of the occupants.
