SRD991 RCV Intelligent Valve Positioner
DESCRIPTION
The SRD991 Intelligent Valve Positioner offers the most advanced
technology available on the market today.
The technology includes, among others, an infrared interface
for wireless operation and configuration, a multi-lingual full-text
graphic LCD and an availability with the choice of all in the process
automation applied communication protocols. It offers enhanced
applications and methods to analyze recorded stroke data.
All the diagnostics features can be easily configured and displayed
by the Positioner DTM (VALcare). Moreover, the Positioner DTM
enables editing a complete health report of the valve with all data
of configuration and diagnostics.
The SRD991 also has the capability to control a Partial Stroke
Test (PST) that offers operators a tool to identify the trouble-free
function of ESD (Emergency Shut Down) valves.
