Features & Benefits

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

    Not sure if I was just unlucky, but part came apart during install. And yes, before you ask I did pre-lube the o-rings with clean system oil prior to insertion into evaporator. Had to use long hemostats to pull out lower section (grey in picture) after it broke off red colored section. Almost ruined a brand new Evaporator I had purchased at same time. I ended up using the standard orifice tube that came with the evaporator Waste of $20..

    Cons: expensive, poor quality

    So far so good

    Don't know how much better it works because I think I may have too much oil in the system. Blows a constant 50 degrees no matter what, too much oil ? My only complaint is the O rings were too fat and would not fit into the tube, change those with the slightly skinny ones from the optional repair kit and it went in fine. Considering most spring,summer,and fall days here in Houston are anywhere from 85 to 105 degree range a constant 50 from the vent is a blessing, even though I'd rather it be in the 35 to 40 degree range. Once again maybe too much oil, kind of hard to tell without a complete flush and start from scratch.

    Pros: Keeps temp steady

    Cons: a little pricey, and the Orings were too large to fit
