ControlAir recently launched their expansion of the Type 2000 electro-pneumatic valve positioner series to include worldwide safety approvals for use with natural gas when paired with the Type 950 explosion-proof I/P transducer. The electro-pneumatic valve positioner mounted with ControlAir’s Type 950 explosion-proof I/P transducer is CSA, FM, and ATEX approved for use with natural gas. The natural gas package (CA2022/2023) was designed as an option to deliver safe, stable and accurate control of rotary and linear valves in applications using sweet natural gas in hazardous environments. The CA2022/2023 electro-pneumatic positioner is a NEMA 4X (IP 66) enclosure that provides rugged resistance to severe industrial environments and is designed for both intrinsic safety and explosion-proof operation.
Natural gas from the pipeline is used to supply the inlet pressure to the CA2022/2023 electro-pneumatic valve positioner that accurately positions the valve stem proportionally to the command of the input signal received from an electric controller. The high accuracy of the CA2022/2023 electro-pneumatic valve positioner surpasses most control system requirements
