Dear Experts,

 

The Data sheet for Control Valve calls for Seat Material of Trim as Stellite 6 + ENP and Supplier is offering SS 316.

Whis is better - Is it Stellite 6 + ENP or SS 316?

 

Info: Service to be used is Sour Service.

Temperature : 60 Degree Centrigrade

Inlet Presure: Max. 0.5 bar g

Otlet Presure: Max. 0.3 bar g

 

Appreciate to see response ASAP.

 

Regards

VPV
