When a pressure spike occurs, RAPTR™ opens its automated relief valve, directing drilling fluids back into the active system and immediately reducing standpipe pressure (SPP). This relief action is controlled and precise; once SPP is reduced to the reset SPP threshold, the valve closes, allowing pressure to build back up in a controlled manner and full flow to return to the driller.
RAPTR™’s relief valves incorporate a hammer-on mechanism with a choke insert, creating a controlled bleed-off that reduces the time required for pressure equalization and connections. This controlled approach eliminates atmospheric release, removes the need for personnel to enter hazardous zones to manage rupture pins, and minimizes connection times. The result: no unnecessary NPT, no system restart, and no short trips or remediation actions following a pressure spike or overpressure event (OPE).
