Hi to all out there!

What is the purpose of relief hole side on the gate valves and how does it works?

Are there any design requirements why do we need to install these type of valves?

Because I've seen this type of valve at site installed near control valves, equipments, drain line, vent line and in prv's.

Are there any effect on the maintenance or operation purposes?

I must admit that I have no idea what you are talking about! Can you refer us to a web site link that shows this or a drawing or a picture, something to give us a better understanding of the question.

Interesting???????
