I am working on vertical inline multistage pump (VS8) and I lnow that these pumps have standard face to face dimensions like butterfly valves have for pipe connection. But I can not find related standard for pumps.
Hey there!
I am on project of designing of pneumatic-leak testing machine for checking of leak in 3-piece floating ball valves of size NPS 1/4" - 2".
While calculating pressure decay in system, for e.g. NPS 2" valve has volume of appx. 240CC so considering leak of bubble of dia. 0.5mm/ 1- sec...
Hey there!

Hello!
As people are heading towards Industry 4.0 concept, so for that most of need is to connect valves in a industry with SCADA system.
I am not that much good in electicals & electronics. I am wondering what are the possible ways to connect a ball valve with SCADA systems.
According to my...
Hello!
I am working on project for hydrostatic testing of ball valve according to API 598. In this project, I am clamping the valve using hydraulic cylinder, Once valve has been clamped, pump wil start pumping the water and valve will start filling with water. I am planing to fill this valve...
Hello!
I was refering to standards ASME 16.34 & MSS SP-25, According to that for every ball valve (for e.g.) there is a name plate i.e. containing basic details of that valves are required to attach with ball valve. For this i have a question that Is it compalsary to attach a SS plate on the...
Hello!
I was refering to some companies who are manufacturing ball valves, On their sites they are providing an option of spring return handles (they also call it Deadman handle). This kind of handles are something new that i found during surffing so, I am wondering what can be the aplications...
