STI

UP-2 is an analog positioner available in pneumatic and electro-pneumatic versions. The positioner has a heavy duty design making it suitable for use in very harsh conditions. It is used as the control part of the pneumatic valve set in oil and gas, refining, chemical, power, metal production and other fields with automated systems. The UP-2 pneumatic version accepts a 3-15 psi (0.2-1 bar) signal and the electro-pneumatic version a 4-20 mA signal. The positioner is based on

SHP is a high-capacity and high-precision digital-pneumatic positioner, mainly used as valve care controller. Its flow rate, the highest on the market, and its control algorithm system and logic, patented by STI, guarantee unique dynamic performances and very low stroking time at the same time. Advanced diagnostic (On-Line & Off-Line) developed to meet all customer needs.

STI FT FasTrak is a high-capacity, high-precision digital-pneumatic valve controller that replaces a conventional positioner. It has an excellent dynamic performance and high flow (Cv = 2). Configuration and calibration is carried out with a HARTTM device or by self-calibration. FasTrak is compatible with double and single acting actuators, with or without a spring, a piston or a diaphragm.

STI DT DT DigitalTrack Positioner is a loop-powered instrument. As a control part of the pneumatic valve set, this positioner is widely used in petroleum, chemical, electric generation, metal production, light industry and other fields of automation systems. This product accepts a 4-20 mA valve setting signal from the control system; at the same time, it receives the actual valve signal through the local sensors. The two signals are compared by control software in order to
