SandPro is driven by innovation
and market awareness

Improve performance with electric-over-hydraulic
emergency shutdown control system that enables
condition-based monitoring and maintenance.

The mSafe2 safety valve control system enhances well safety increases operational efficiency, lowers maintenance costs and maximizes production.

Manual, remote and automated operations

Implement condition-based monitoring and maintenance using valve status data communicated via SCADA, telemetry or downloaded from onboard memory

ELECTRONICALLY ASSISTED HYDRAULIC CONTROL

Field-proven in Latin and North America, the mSafe2 design integrates electronic control and an electrohydraulic pump to ensure the safety and performance of hydraulically actuated safety valves used in emergency shutdown applications.
The controller precisely and reliably manages 2 valve positions while monitoring hydraulic pressure in the actuator and actuator lines. The acquired data supports condition-based monitoring and maintenance practices that can significantly improve safety and performance.

Real-time and historical valve data is transferred using the
wellsite SCADA system. Months of data can also be saved
in onboard memory and downloaded via Modbus RS485 or
Hart communication protocols.

Condition Based Monitoring

The mSafe2 controller’s ability to acquire and communicate precise data on even small changes in hydraulic pressure
supports condition-based monitoring and maintenance in many ways:

PREDICTIVE VALVE MAINTENANCE

Predictive maintenance is enabled by early detection of small operational anomalies. Partial stroke testing allows diagnosis of potential valve failure without stopping production and with zero emissions. Maintenance is reduced and easier to schedule, and production delays are minimized.

ACUATOR PRESSURE STABILIZATION

Pressure stabilization eliminates progressive valve
closure and associated wear with mSafe2 monitoring
and automatically compensating for temperatureinduced variations.

LINE BREAK DETECTION

Identifies gradual losses in pressure over time preventing hydraulic releases. Deviation from the pressure gradient prompts an mSafe2 programmable alarm or valve closure.
