If you want to reduce the pressure downstream to a preset value, the valve is a pressure regulator and the pressure tap (internal or external) is locate downstream. Lots of manufacturers provide this type of PRV ; see Emersonprocess (formerly Fisher) model 95 for example.
If you want to control...
Hello Mishaal,
You don't mention if the valve is remotely operated or not.
If so, the stroke count can be done into the PLC program which is controlling the valve.
If not, you have 2 other solutions :
1- you can install open or/and closed limit switches on the valve handwheel

I have to purchase anti-surge control valves which require an opening stroke time of 2 sec. max.
The valves are globe+cage type with spring-diaphragm actuator (fail-open) with a "flow tends to open" plug.
The valve supplier propose me two ways to achieve the fast opening feature ...
Hi all,
I have to find a valve test bench for hydraulic testing.
Valves connection : flanged.
Valve type : ball, globe, butterfly, gate.
Some cases require tests at 1040 bar (14500 psi) !
This rig shall test 3 valves at the same time with differents pressures.
Unilateral clamping is foreseen...
