Dresser Masoneilan's Smart Valve Interface Advanced Performance (SVI II AP) is an intelligent digital valve positioner. SVI II AP offers advanced control technology for pneumatically actuated valves with a non contact Hall Effect sensor, providing higher precision and reliability, greater flexibility and ease of use. ValVue is a communication software tool used to configure, calibrate and perform valve diagnostics with the SVI II AP utilizing HART communications protocol.	The SVI II ESD can be implemented using a 4-20mA signal, 0-24Vdc or a combination of both. The single 4-20mA solution is most desirable as it is SIL3 capable while at 4mA, allowing the device to execute the safety function while active. Substantial benefits are realized in capturing shutdown events, allowing continuous HART communications during a trip and facilitating local panel annunciation using the built-in discrete outputs. In terms of PST execution, the following are available: local LCD display, remote HART access, remote use of 4-20mA analog signal, and finally, built-in scheduler functionality. The SVI II ESD automatically captures the PST in its non-volatile memory and stores the analysis. Two signatures can be stored, allowing the Valvue ESD software to automatically and regularly synchronize its database with field data.	The FVPTM - Fieldbus Valve Positioner, is a digital valve positioner and PID process controller. The FVPTM offers highly advanced control technology for pneumatically actuated valves, providing higher precision and greater flexibility. A Fieldbus version of ValVue soft-ware is available.
