Just a valvestem.... in HDR

At unit EC 20: the suctionvalve of boilercirculationpump "A".
Normally this valve was only operated when maintenance had to be done at the pump and we had to shut the valve.
The pump was almost maintenance free).
The curled "thing" is called a pigtail and is a small safetyvalve.
There is a pressure of 180 bar behind it....
Two men were needed to do that (by hand...)

Better in LARGE....
