Thank you, so can we conclude XM-19 superior than 316L as stem material for opening/closing valve please.

For a Gate Valve Customer asking A182 F316L Stem material instead of A479 XM-19, I want to know if there is any disadvantage in using XM-19 over 316L in process & power industry please,

Thank you for input, i don't have test set up to check practically high temp, is there anyway to theoretical way to determine temperature at Hand wheel.

When Stem flows thru a 2" Class2500 F22 Globe valve at 550°C, how do i calculate temperature at Stem, Packing & Hand wheel.

thread408-445393 Could anybody advice how B148 UNSC95400 is superior than A582 Grade416 for Yoke Bush please

Stem material used A479Ty.410Cond.2/ A182GrF6aCl.3 due to higher yield strength, but customer wants only F6a Cl.2, what could be the reason please, Gate & Globe Valves

Lantern ring can be used in Valves Stuffing bore for Vacuum application too.

Could anybody share information on Needle valve design please

Valves are used for drain lines please

1.In Pressure drop calculation(Steam), Pressure loss grater than fluid pressure. 2.Flow rate, Cv & bore added.

How to calculate please, 1. Pressure drop if operating pressure 55.2 bara & temperature 600°C, flow rate 1.166 Kg/S, Cv 9.5 USGPM & bore 19mm 2. Pressure drop if operating pressure 259.6 bara & temperature 599°C, flow rate 1.131 Kg/S, Cv 10.5 USGPM & bore 25mm 3. Noise

Valves are used in both Power & Process industry, High temperature & Corrosion application please

Inconel X750 & X650, Which is the best out of two material for Spring used in Lift Check Valve, please

Thank you, F91 T-globe valve used in thermal power plant had passing issue, when disassembled found 316 with Stellite6 Hard face Disc eroded at seating area, so wanted to understand more about drain valves.
