Two things for this service: NO soft seats, metal to metal only, and you cannot install with flow down in a vertical pipe.

Crane's Tech Paper 410 has a section on this.

TBP is right but if you chec out the HyGrade design they have an integral flapper and pin. Really only 4 parts to the valve. It works like a champ.
They have a double seated design so they can get tight shutoff in metal to metal. You cannot however ignore the proper piping practices with any check valve inline or you will get unfavorable results. Make sure you have the required pipe diameters before and after the valve.

These are much lighter than traditional swing check valves and have better response times.
For steam service normally the seat faces are hard faced (Stellite).
The two major manufacturers of this type of valve are Stockham (Crane) and Goodwin International.
