For a rubber curing press, I want to test removing the product without the use of pneumatic ejectors. Currently there is a 90 psi supply controlled by electronic solenoid valves, automatically activated. If I shut of the air supply to the ejectors, will there be any negative effects to the solenoids?

I see no reason there would be a problem. What do you expect would be a problem?

Unless the air is used to cool them as well as actuate, if they can take the temp then you are OK.

The only problem I can expect is they would stick in an intermediary position, and as the machine is in use may cause some down-time. But I believe this is a special case, and they are not cooled by the air so I will give it a try. Thanks!
