The expansion valve is a component of the automotive

The expansion valve is located downstream of the receiver drier in the A/C loop. The expansion valve receives the refrigerant fluid in an already-filtered, 100% liquid state.
It then reduces the refrigerant fluid pressure before it enters the evaporator. This pressure drop cools the fluid, which is then sprayed into the evaporator. The expansion
valve for car A/C is always attached to the evaporator.

The expansion valve for car A/C has a few different roles:

❊It controls the drop in pressure in the A/C system needed to evaporate the refrigerant and generate cold.

❊It controls the flow rate of the fluid in the evaporator.

❊It controls the evaporator output temperature (superheating).

SENPAL expansion valve has a unique specification for tonnage, superheat and maximum operating pressure (MOP) based on the specific system. Some A/C performance
issues can be traced back to an incorrect valve as a result of misapplication or low quality. 

Our experienced research & development center utilizes the latest software and precise measuring equipment to ensure product quality. Our expansion devices are
specifically calibrated for optimum cabin comfort for both the driver and passenger.
