Expro has announced the introduction of a new Power Relief Valve (PRV) system which reduces the man hours and rig down-time historically associated with operating and maintaining traditional mud pump relief valves and systems. The PRV MAX is an accurate and automated relief valve with an integrated hydraulic actuator, separate hydraulic power unit that can be mounted directly to the valve or within 20 feet of the valve, and a remotely mounted ‘touchscreen’ control panel. Ideally suited for offshore rigs, floaters, vessels and jack-ups interested in avoiding costly down-time events, the system brings innovative solutions to the problem of protecting positive displacement mud pumps from excessive pressures. It increases relief pressure accuracy, increases repeatability, and allows reset to occur in a time-efficient and cost effective manner. The PRV MAX is constructed of non-interacting mechanical components, meaning that a single point of failure will not spread to other valves. The system is virtually maintenance-free and is constructed of tungsten carbide sealing components to provide high-erosion resistance and extended trim life, without the use of elastomeric components. The system is ATEX certified for hazardous areas.
