Core Technical Advantages
-
Natural Gas Certified: The i2P-100 is specifically approved for use with sweet natural gas as the pneumatic supply, making it an ideal choice for remote oil and gas production sites where compressed air is unavailable.
-
Superior Contaminant Tolerance: The free-flow pilot stage design and large internal air passages are engineered to resist clogging. This makes the unit highly tolerant to dirty or poorly filtered pneumatic supplies, reducing maintenance intervals.
-
High Flow Capacity: Unlike many standard transducers, the i2P-100 features an integral output relay with sufficient volume to drive most valve and actuator combinations directly, often eliminating the need for additional volume boosters or positioners.
-
Environmental Safety: Tested in accordance with ANSI/ISA Standard 12.27.01 (Single Seal), the device features separate housing compartments that isolate sensitive electronics from the pneumatic process, preventing gas migration into electrical conduits.
-
Low Operational Costs: The design minimizes steady-state air/gas consumption, helping plants reduce total ownership costs and meet stricter environmental emission standards.

Applications and Industry Sectors
The i2P-100 is the industry standard for converting electronic control signals into mechanical force in demanding sectors.
-
Natural Gas Midstream: Controlling pressure and flow at gate stations and remote pipelines using the process gas itself as the supply.
-
Chemical Processing: Driving control valves in areas where electronics must be isolated from corrosive or humid pneumatic environments.
-
Offshore Platforms: Operating vital pneumatic loops where space is limited and high flow capacity is required without extra boosters.
-
General Manufacturing: Modernizing legacy pneumatic loops to integrate with modern DCS or PLC control systems.
