The problem is that this valve is so old that the manufacture no longer exists :-( So we are not able to get support from this side. What I was hoping is that there are some kinds at standard that describe how it should be carried out.
We have very accurate and calibrated measurement instruments...
Hi
At the company we got a reguest to test some P/V valves with opening pressure on 3 mBar and -3 mBar.
But im not sure how to test them.
There are 2 types of valve´s that we will like to test, one of them vent to atmosphere and the other one vent to pipe.
We got high precision gauge to measure...
