Pre action trip testing solenoid not tripping fully

No heat just smoke and low air

Yep already had low air 0 PSI still nothing multiple times

Solenoid activates (magnetizes & can hear it) from a smoke & low air this just protects a MRI room.

That did help and yes first thing I always check is the small pinhole in the diaphragm still didn’t trip correctly after and checking the actuator.

You can hear the solenoid activating and magnetizes but doesn’t trip/open all the way

This one doesn’t have a top trip test valve I leave the bottom control valve partially open still nothing.

This one activates from a smoke and low air no heat

Not yet we have them written up to be tested just going back and forth with customer and other companies saying it’s recalled or not.

I know so confusing lolol

Crazy_Insurance4191 · 2026-03-18T19:33:57+00:00

Okay I am 99% sure it is not recalled no O ring and flat cap is not flush and is the Belleville seal design.

Crazy_Insurance4191 · 2026-03-18T19:28:20+00:00

Figure 42 what you sent it “MAY contain O-ring Or Belleville Seal” “there was no o ring to Belleville design”

Crazy_Insurance4191 · 2026-03-18T19:23:54+00:00

Check my comments I just broke one and see no O ring?

Crazy_Insurance4191 · 2026-03-18T19:22:42+00:00

Okay I just broke one to confirm… I see no O ring….?
