I am thinking of buying solenoids from the falcon pejo, which is the sponsor of our site. A friend said that he will change this piece with the valves, he wrote it .... do we need to get it too ... otherwise, we are just finished with these 2 valves.And I am waiting for help from the friends in Antep to make this change. There is no automator master I know. I did not trust him, I did not trust him.
