Metso’s Nelprof 6 valve-sizing software enables engineers to select valves and compare various forms of product data. The new version extends earlier Nelprof versions with two new calculation modules, which enable the selection of intelligent automated on/off valves and emergency valves. Special safety requirements, such as an actuator-sizing safety factor or a complete valve assembly safety-integrity level, can be evaluated with the new tools. Nelprof 6 can be used to select all of Metso's automated on/off and emergency valves. Performance analysis can be used to study valve controllability in a closed control loop. The module also includes multiphase flow sizing as well as noise and cavitation prediction analysis. An on/off calculation tool allows the selection of all Metso metal- and soft-seated on/off valves with advanced actuator sizing, including adjustable safety factor and torque key figures. The SIL module for final element PFD (probability of failure on demand) calculation allows multiple final-element calculations that take into account several design criteria.
