Most valves have a WSP rating stamped on the other side which is "Working Steam Pressure".

I always thought that was

"Water Service Pressure", but you may be right.

WSP on ball valves

Paul is correct. WSP on ball valves stands for "Working Steam Pressure" and is generally a lower pressure that the WOG, or "Water, Oil, Gas" rating.

S,SP and WSP

all mean the same. The maximum rated or working pressure corresponding to the steam temperature that must not be exceeded when the valve is used in steam service. CWP This is the maximum flow-medium pressure at the ambient temperature to which the valve may be subjected during normal service. This is also referred to as water-oil-gas(WOG) rating. These deffinitions are from Piping Handbook by Nayyar.

Thanks, Dave and Bob

Always learning on The Wall...

The only ball valves I specify for steam are Jamesbury-Neles, but maybe I can expand that list just a bit...

Thanks again-
