Main Steam Drain Valve
Main Steam Drain Valve
(OP)
At our plant, we have 2" globe valve for our main steam drain system which always failed to operate by high temperature. This will not happen during first start up (cold condition). For your information this valve has been being used for turbine start up. The normal operating temperature is 520 deg C and pressure 10340 kPa. We like to change the globe valve with a ball valve which we hope it will solve the current problem. Before we change the valve, we have to make sure that we replace with the right ball valve including size, cv and spec/app. Can any body help me to identify the right high temp/ press ball valve (spec,size) which equal to the current globe valve.
