The key to perfect flow control

Selecting the right Valmet valves for your processes is vital.
Nelprof helps maximize end-user process efficiency and minimize
raw material losses that can occur if valves are not a perfect fit.
Nelprof avoids common issues by optimizing valve selection with
control performance analysis.
With Nelprof it is also easy to view and adjust valve parameters
based on particular needs, further refining valve and actuator
selection for any process and application. Because our valves are
designed to work together, compatibility is guaranteed for fast
and easy automation.

Solutions for valve applications

Complex systems are only as strong as their weakest link. Nelprof
software offers a solution for demanding applications affected by,
for example, cavitation, flashing, erosion and gas noise by ensuring
exact and appropriate valve, actuator and valve controller
selection. Pneumatic components can also be included in valve
safety calculations (SIL) to provide a complete understanding of
the system.
Not only are Valmet valves manufactured to the most stringent
standards possible, but they are backed up by extensive services
and expertise. Nelprof is reliable and accessible through your web
browser, keeping your process data secured.

Optimized control valve selection with extensive control performance analysis.

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. 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. Evaluating control valve sizing with fixed flow resistors and attenuators is also possible with just a couple of clicks. Naturally, optimized actuator sizing and selection is an integral part of control valve sizing in Nelprof™.

Fast and reliable on/off valve 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. By using the tool, you can select the actuator more effectively and accurately in the engineering phase, compared to conventional actuator selection. Returning to the documentation and revision of the sizing is, of course, also possible whenever needed in the later phases.

 

Optimizing safety-critical system components in valve selection

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™. In addition, one to several pneumatic components can be considered in the calculations.

Easy to use and reliable in results

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. 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.

We sincerely welcome you to take a closer look into Nelprof, our valve selection and sizing softwae.
