The valve is on the steam supply line to turbine. Utility steam pressure is at 170 psig, 385F. This is a 2" ball valve at the inlet of turbine driven pumps. I have rated flow requirement but do not know the normal flow requirement. Is this something that can be obtained from the rated flow?

I need to determine Shut off pressure and temperature. Instrument asking for Shut off pressure and temperature. This valve is a ball on/off valve. I do not have manufacturer data.

How should I determine the shut off for a full port on/off valve?

Swing check valves.

Need to add stream table to my flowsheet showing line size, pressure, flow rate,temperature and velocity. I have V8.8 version. Does anyone know how to do this? Thanks

NEED TO ADD VELOCITY TO PFD TABLE- DOES ANYONE KNOW HOW TO DO THIS IN HYSYS V8.8?

Thanks for the responses Wrong symbols were used on the drawings! They are not stopples. I found out they are check valves not stopples but called out that way.

For pressure drop calculation- what would be resistance coefficient and equ. length for stopples? Would be the same as the pipe size?

Does the cycle time matters to lowering the dew point? For example 10 min. of NEMA cycle vs. 3 min of NEMA cycle

I need to spec. out an on/off full port valve on the 150# steam line that feeds the turbine. This valve is a 2" ball valve. I do not have Cv of the valve to come up with delta p thru the valve. How should I spec this valve when Cv is not known yet? Thanks

We need to mix Boric Acid powder with 3% boric acid and 37% sodium sulfate, and need to keep the solution warm at around 130F. I have been searching for storage tanks and found out carbon steel is not a compatible material when storing boric acid. It was recommended to do tank lining. Does...
