avalveman is correct. Changing set pressure of valves is not outside the realm or normal duties for PSV repair shops. As noted, the spring would have to be swapped out for the correct one (spring range) as defined by the spring charts. Keep in mind the reduced capacity impact and ensure that...
You may want to look at Oilgear. https://oilgear.com/product/wnc/ . They tend to be custom user specific builds.
Autoclave are also a known option but generally capacity is limited compared to the Oilgear ones.
Most of your major valve sizing manufactures have their own in-house sizing software (Farris/Consolidated/Anderson Greenwood Crosby). The nice thing about using those is that you get to see what product line they would consider for the given data input.
However, you also have standalone...
I have seen that program being adopted at a site. They have a set of PSVs that vary in set pressure depending on the pipe class. The driving force in the sizing is the capacity of the hydrotest machine (which is normally very small) and the idea that it continues pressuring up. Given the normal...
Hello everyone,
This is my first post but I have made use of this site a few times. A lot of great information contained within this forum.
My question is a simple one (I hope) and revolves around the spring itself used in PSVs. I recently moved to a position where I am inspecting the PSVs...
