Another Apeks question-Exhaust valve

[buddhasummer]

Does anyone know if the exhaust valve AP1429 on the ATX series can be replaced by the exhaust valve AP6223 on the XTX series?

I ask as Apeks say:

"A new silicone exhaust valve has been used on the XTX200 regulator improving breathing performance."

I have asked Apeks but they have not replied as yet.

Thanks I have my answer, this form Apeks:

"No they cannot be interchanged each exhaust valve is specific to each regulator type."

Figured this would probably be the case given different part numbers.
