Valve position indicators
28 March 2016
Offering an accurate and reliable alternative for existing position indicators in the market, Netherlocks Safety Systems has launched its next generation Valve Position Indicators for manual multi turn valves: the VPI A-series and S-series.
A mechanical counting mechanism is protected by a aluminum (A series) or AISI 316 (S-series) housing. Integrated sensors detect the end positions of the counter and transfer that information directly to the control room, giving a real life valve position signal to the DCS.
VPI is an intrinsically safe, Atex and IEC Ex-certified product approved for use inZone 1 classified areas.
