Does a change in valve construction by a 3rd party require a new SEP/PED declaration?
Does a change in valve construction by a 3rd party require a new SEP/PED declaration?
(OP)
Hi folks, this is a quality assurance question that I'm looking for advice on.
When a valve is supplied to SEP/PED by an OEM and then a vendor modifies the construction, does the modification need to covered by a new declaration to SEP/PED?
In this instance we have a valve where the O-Ring on the Ball Valve Stem, above the fire-safe gasket, has been changed out for another type (compound) by the Vendor.
This is after the OEM supply, so does the vendor have a responsibility to provide their own declaration to SEP/PED or can they rely on the OEM's on the basis the change is not significant in terms of design?
I feel that they do, as the OEM never agreed to the change in their product but I could be interpreting the standard too conservatively.

Basically the way I read PED was that if a 3rd party changes the design of a valve, they then own it and must certify it.

Also, besides reading the PED, verify it with OEM for the authorization of this vendor and the warranty coverage due to the valve condition.
