Replacing 1A valves

Hi,
I have replaced 5 1A Hoffman valves to replace the same ones which were 5 years old. Three of the five are letting steam out when steam reaches them. The old ones did not do that. Any suggested solutions.
Thank you.

The boiler is running on 0.5 and 1 on the internal wheel. I will post pictures. The old ones never leaked steam before. I shakes them and put them back in, still same issue.0

Do you have a clean pigtail and an accurate gauge to read?0

Pigtail cleaned at start of season. Gauge looks accurate. Boiler shuts down when reaching 1.5-2 psi. I got a box of six. I will try a different one.0

The Honeywell grey box.
Pigtails are copper. I will try swapping them.
I put a new 1A and it only lets out minimal vapor for a little bit then closes. I think the other one was defective. I will return to store, not sure if they accept returns.
Great help to find this forum. Thank you.0 -

I will return those 1As and get the vent rites.
Thank you.0 -
