	It's time to put some air on that keyboard too. Some of the keys appear not to work. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	A P #1- Can't supply any humor tonight, all laughed out, BUT ----> It depends upon the type of valve you are using. Solenoid valves generally need a slight pressure on them to operate, no air no operate. Pilot operated valves require air to the pilot to operate the valve, no air no operate. If the valve is operated with an air cylinder independent of the air passing through the valve and the cylinder has a spring return on it, the valve will operate. Note that the air to the cylinder can not be the air that is passing through the valve, it must be an independent supply of air. Otherwise the system will not operate.
