Handwheel Valve Position Indicators
29 October 2012
Bilbao Petronor Oil Refinery, part of Spanish oil and gas giant Repsol, has ordered 1160 wireless VPI units from Dutch valve safety specialist, Netherlocks. Following a successful three year pilot program, the new equipment will replace existing valve position signalling at the 220,000 barrels-per-day refinery.
The VPI (Valve Position Indicator) was designed by Netherlocks to provide a reliable feedback signal from hand wheel operated valves, converting the open and closed positions to a digital signal by way of a mechanical counter system.
Overcoming traditional issues about mounting strength and signal reliability, both the VPI’s mounting method and counter use well-tested and proven designs, which have been used successfully in Netherlocks’ mechanical interlock systems.
