Reading my title you would think face to face is saying something to someones face and not behind their back???????????
Well YES that is true BUT in this case its totally something different.......
Face to face means you should measure from one side of the valve, pipe or flow meter and that measurement is your face to face value.... Strange but true... :-) Imagine phoning you fiancé and asking him to help you figure it out and he doesn't even know what they looking for....
So i walk down to the warehouse to go measure the face to face of the valve and this I'm going to do with my RULER not a measuring tape no A RULER and a pink one!!!!
And while I'm there measuring the face to face i even learn how to work out your PCD.... And NO i dont know what that stands for i just know it sounds fancy..... But anyway, you work out your PCD from one hole on the flange of the valve to the hole across from it and that is your PCD!!!
Happy Engineering Everyone.....
