A High-Integrity Pressure Protection System (HIPPS) is a safety instrumented system (SIS) designed to prevent over-pressurization in gas, chemical and oil refinery plants. The HIPPS acts as a barrier between a high-pressure and a low-pressure section of an installation, shutting off the source of  the high pressure before it exceeds the system design pressure, thus preventing loss of containment through rupture (explosion) of the line or vessel. We can provide a wide range of side and top entry ball valves suitable for this service, in accordance to API 6A / API 6D requirements and SIL3 certified.
