20 inche gate valve with SOLID WEDGE
(OP)
My client is asking for 20 inches gate valve (WCB body) with SOLID wedge. As far as I know, larger size valves comes with flexible wedge only. Please correct me if I am wrong & give your valuable advise.

Even in that case they still wanted flex wedges in some of the larger lines and they installed steam purges on the valve body to occasionally blast clean the wedge groove.

For smaller valves, it is easier to achieve the seat to disc alignment, thus a solid wedge is possible.
My advice, let them know a flexible wedge is the better option and the potential for future maintenance headaches. If they do not agree with you, then give them what they're paying for.
