The variable orifice valve (VOV) was developed to improve the performance of a standard fixed orifice tube (FOT). A variable orifice valve will significantly improve A/C system performance at idle and low speed driving, especially in high temperature climates. The variable orifice valve is a direct replacement for the original fixed orifice tube. No physical modification is required to upgrade the A/C system.
- Improves system performance in hot idle situations
- Delivers five to twelve degree colder vent temperatures
- Improves city driving fuel economy and emissions
- Reduces compressor load to help extend compressor life
