I bought one of these in February this year and it worked as advertised, so I ordered 4 more. None of them worked, but since I received the 0.02-0.8 mpa version instead of the 0.0-0.8 mpa that I ordered I returned them and reordered. This time 3 of 4 were the correct version, BUT none of them work. Symptoms are like this, the valve opens and closes fine as long as there is NO pressure on the inlet side BUT it does not open if there is even a little pressure (1 psi or so) on the inlet side. What good is a valve that works like that?
