SMART VOV™

L10 L11 L12 L13 L14 L15 L16 L17 L18 L19 L20 L21

For R-12 & R134a A/C Systems

Drop-in replacement for ineffective fixed orifice tube (no modifications required) VARIABLE ORIFICE VALVE

Complete coverage with only two numbers

Now your customer can have: l 5° - 10°F colder air (at hot idle) l Much improved performance when converting from R12 to R-134a l Reduced compressor load, improved city fuel economy & emissions l Extended compressor life

l The Smart VOV is a new refrigerant expansion device that substantially increases air conditioning cooling at idle and city traffic conditions. l It is a self-contained “drop-in” replacement for fixed orifice tubes; it creates colder discharge air temperatures by automatically reducing the orifice area at low compressor speeds such as when idling or driving in city traffic. l Test vehicles equipped with Smart VOV have demonstrated excellent performance, outstanding reliability, and extended compressor life in over one million miles of severe duty desert testing.

FOOTNOTES: 1. Liquid line may contain non-replaceable original orifice tube – If this is the case, you can use commonly available inline orifice tube housing repair kit which will accept VOV (See Fixed Orifice Tube Replacement Kits, No.s 923335 or 923659 for instructions).

TECH TALK – how it works The Smart VOV (variable orifice valve) uses system pressure and refrigerant flow to move a metering piston relative to a fixed opening in the sleeve. The piston movement is resisted by an attached spring. When idling at high ambient temperatures, the piston shifts to a smaller metering area similar to a TXV. This com pensates for the reduced compressor output and increases the cooling performance. The Smart VOV also has a unique re-open feature which reduces compres sor pressure for severe idle conditions. At highway speeds, the Smart VOV operates on a large orifice. The net result is better performance than a TXV without the complexity or reliability concerns. Unlike a TXV, which has constantly moving parts and small internal clearances, the Smart VOV is stationary during most operating conditions and has large internal clearances. It’s low friction floating design insures smooth operation and extremely long life.
