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.
