Valve Position Indicator joins SMV line
Sep 1, 2006 12:00 PM
Hansen Technologies introduces the Valve Position Indicator (VPIF), a digital monitoring module added to the Sealed Motor Valve (SMV) product line. It is standard on all models: HMMV, HMMR, HMXV, HMMVC, HMMRC, and HMXVC shipped after July 1, 2006. The VPIF monitors the valve position during normal operation and is used to recalibrate the valve after service work is performed.
A large LED display allows for viewing of the valve position (in percent) during normal operation. The VPIF contains an internal independent 4- and 20-milliamp current source, which is switch-selectable for recalibration at the valve 0% 4-mA (closed) position and 100% 20-mA (full open) position. After calibrating the valve, the switch must be returned to the middle position (automatic) and the calibration key removed.
The VPIF can be mounted on or near the valve for ease of use and visibility. It can be mounted up to 10 feet in any direction from the valve. VPIEC Extension Cables are available if more length is required.
All VPIF units are factory-tested and fully assembled; retrofit kits are available to update existing SMV installations.
