IMI CCI

Mechanical HIPPS - High Integrity Pressure Protection System

Self-contained, SIL-rated protection system isolating high pressure with no need for electric power.

Provides certified SIL 2/3 protection by isolating high-pressure sources without needing external power or electronics.
Offers robust performance in remote areas with a self-actuated or self-contained design tailored to site conditions.
Integrates proven IMI valve and actuator technology for fast closure, reliability, and simplified maintenance.

The Mechanical High Integrity Pressure Protection System (HIPPS) from IMI is a complete, fail-safe solution that shuts off high-pressure flow at the source without requiring any electrical power. Ideal for remote or unmanned sites, it is available in pneumatic self-actuated or hydraulic self-contained configurations. Certified to SIL 2 or SIL 3 (with single or dual valve setups), the system uses the process pressure as its closing signal. Designed to IEC 61508/61511 standards, Mechanical HIPPS integrates IMI Truflo Italy’s ball valves and IMI STI actuators, offering fast response, bi-directional shut-off, and zero pressure drop, even in piggable lines.
