HIPPS (High Integrity Pressure Protection Systems)

Flowbus can supply not only an actuator but a complete tailored solution to meet our customer’s application. From basic ancillaries, through the HIPPS solutions, Flowbus is able to use their years of valve and actuator experience to enhance performance and provide the perfect solution to client’s requirements. A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through rupture (explosion) of a line or vessel. Therefore, a HIPPS is considered as a barrier between a high-pressure and a low-pressure section of an installation.

Flowbus Suitable for use in SIL 3 & 4

Safety Integrity Level (SIL) is defined as a relative level of risk reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a Safety Instrumented Function (SIF). Four SILs are defined, with SIL4 being the most dependable and SIL 1 being the least. When you request a final control element for the safety systems, Flowbus offers the ability to perform according to the IEC61508 and 61511 standards. The EP Series actuators are certified to SIL 3 without the partial stroke systems and SIL 4 with periodic proof testing device.
