HIPPS
HIPPS is applied to prevent over-pressurisation of a plant or pipeline by shutting off the source of the high pressure. The Mokveld HIPPS totals over 50 000 (with over 3700 valves) operational years and are therefore proven-in-use for high reliability safety applications.
Third parties have validated the failure data of the final element (valve and actuator) on applications with less than 2 seconds stroking time.
Fast acting axial on-off valve with integrated actuator, specifically designed for fast reliable stroking.
The capacity of the axial on-off valve is extremely high, as a result of which the pressure drop is negligible.
Mokveld’s mechanical initiators have an accuracy better than 1 percent of the set point. Failure data have been validated by third parties.
The Mokveld final elements do not require additional electronic systems, like partial stroke testing devices, to meet SIL 3 with a 1 year test interval. A separate technical datasheet on this subject is available.
