Seems simple but I am looking for some software to help calculate the linkage geometry needed to linearize different size butterfly valves driven by a motorized actuator. Actuator has slidewire feedb

Why do valves with the same pressure class get tested at slightly different pressures because the body material is different? (API 598) F316 and A105N for example

"The term trim refers to shafts, seating surfaces on the body and disc, and internal keys, pins, screws and bushings in contact with the contained fluid are also considered trim".

I recently witnessed a pressure test followed by the leakage test. Pressure dropped from 161psi to 159psi for 5,710 ft of 8-inch DI pipe. Is there a way for me to verify the leakage (7.5 gal) theore

What effects would HIPPS (High Integrity Pressure Protection Systems) have when it is used along with PRV on compressor discharge line to prevent the system from overpressure due to block discharge o

I'm working on ball valves specifications and Our client spicify the following standards for fire tests ISO 10497 / API 607 and API 6FA.

In my experience most low pressure applications request 2 piece floating ball valves and when not specified I've always sold the 2 piece floater. What instances would a 150# or 300# trunnion be the pr

I have a question regarding Check valves, what means for a check valve the term "retainer less design"?
