Parker Hannifin Corporation, the global leader in motion and control technologies, recently filed a petition with the U.S. Department of Commerce and the International Trade Commission alleging unfair competition from the dumping of valves used in air conditioning systems by two manufacturers in China.

Specifically, the petition alleges that Sanhua group and DunAn group have and continue to sell front-seating service valves for residential air conditioners into the U.S. market at prices below their cost of production in China, an illegal trade practice commonly referred to as "dumping". Parker is petitioning for dumping penalties which will help to restore fair trade in the U.S. market.
