We discovered your company in 2017. At the time, we were making a machine to wash trucks transporting urban waste. At the beginning of 2018 we installed the first the machine. And this is where we applied your high pressure 3-way solenoid valves. We still tried to promote the sale of this equipment in the following years, but we were unable to do so. One of the reasons was that this type of machine required frequent preventive maintenance, in very harsh working environments. But the main reason was that this equipment had a low probability of sale, and our main business is the self-service washing and vacuuming of light and commercial vehicles. Were we recently start using their valves again.
