Netherlocks Safety Systems, a manufacturer of industrial valve safety solutions has recently launched its next generation Valve Position Indicators for manual multi turn valves: the VPI A-series and S-series. With these new models, Netherlocks offers a highly accurate and reliable alternative for existing position indicators in the market.
In order to spot the open and closed position of manual quarter turn valves, many switch boxes and related products are readily available. However, for manual hand wheel operated valves, operating companies still often create their own solutions with custom made bracketing and proximity switches. The Netherlocks Valve Position Indicator (VPI) now offers an accurate and reliable, off the shelf solution that fits any type of multi-turn valve. A mechanical counting mechanism is protected by an aluminium (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 IECEx-certified product approved for use in Zone 1 classified areas.
