I point directly to the basic data that the OP (Plumbercs) has supplied. We sincerely welcome you to take a closer look at 'm taking the liberty to interject myself into this thread because I believe this is a perfect example of what can go wrong in an engineering project/assignment when there is a failure to communicate correctly and exactly.

Nelprof™ software - utilizes intelligence based on several decades of real-life experiences to help you size and select the best valve solution for any application. With all the relevant parameters on your screen – easily available for you to be revised whenever needed – you can avoid many mistakes and work more efficiently by using the tool. In addition, one to several pneumatic components can be considered in the calculations. The SIL module for final element PFD (Probability of Failure on Demand) calculation allows both 1oo1 and 1oo1D (D standing for diagnostics) final-element calculation that takes into account the use of a valve, an actuator and a valve controller, like the market-leading partial stroke test device Neles ValvGuard™. Optimizing safety-critical system components in valve selection Returning to the documentation and revision of the sizing is, of course, also possible whenever needed in the later phases. By using the tool, you can select the actuator more effectively and accurately in the engineering phase, compared to conventional actuator selection. The on/off calculation tool allows the selection of all Neles metal- and soft seated on/off valves with advanced but easy-to-use actuator sizing, including adjustable safety factor and torque key figures.

Naturally, optimized actuator sizing and selection is an integral part of control valve sizing in Nelprof™. Evaluating control valve sizing with fixed flow resistors and attenuators is also possible with just a couple of clicks. The control valve sizing module includes liquid, gas and multi-phase flow sizing as well as noise and cavitation prediction analysis according to the latest international standards. Performance analysis, which has been one of the most recognized value-adding features in the control valve sizing tool since 1980’s, can be used to study valve controllability in a closed control loop.
