When a valve is newly manufactured I can understand why it needs a full pressure test to ensure the integrity of the casting or forging and to proove the pressure containment ability.

HiI'll try to briefly describe my problem: My hydraulic circuit (the pumps are supplying 130 bars of pressure) consists of a closed-center proportional valve that drives a hydraulic motor (which is us

I'm not too familiar with ARV's however I know the basic principle behind how ARV's work.

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.

so if you have a valve and oil flowing through it... then you shut off the valve... I assume that most of the oil will stop flowing and the pressure will basically be 0 at the valve and atmosphere at

Hi. I have a flow from a pump, and soon after the pump discharge want to be able to take off half the flow at times, and regulate the pressure.

Hello all. I work for an EPC company and one of our vendors is having issues meeting a valve testing requirement in one of our client's specs.

We are currently designing a pilot plant and will need small (1/2" -1") isolation and pressure relief valves for 750 degrees C design temp,
