Modular Electro-Hydraulic
Rotork M-EH modular electro-hydraulic solutions offer a robust and reliable valve automation solution for on/off duty.
Features
Basic (on/off) Designed for simple on-off applications with no partial stroke test (PST) facility or diagnostics, the system is self-contained and features low power consumption in a relay-based system, leaving the input signal handling to the end user.
• Remote control via hardwired signal (electro-mechanical logic)
• Local indication (position / actuator and accumulator pressure / oil level / temperature) via pressure and position gauges
• Minimum flowrate of 30 l/min (adjustable), extendable to any customer request
• Optional accumulator for pressure back up
• Suitable for low-power infrastructures (including solar) – for operation and standby Advanced (on/off) Thanks to the intelligent PLC/EHPC210 controller, the system can be programmed to accomplish any customised logic and includes the following features in addition to the Basic (on/off) product:
• Local control, non-intrusive setting and easy troubleshooting via the user friendly digital Human Machine Interface (HMI)
• Optional network protocol (Modbus® RTU, Modbus® TCP/IP, PROFIBUS®, PROFINET®)
• Local indication (position / actuator and accumulator pressure / oil level / temperature) via HMI
• Modular mechanical architecture and functional flexibility in controller – from basic on/off to multiple voting (1oo1, 1oo2, 2oo2) SIL-rated ESD
• Partial stroke test (PST), full stroke test, solenoid valve test, accumulator monitoring and line break functionality for detailed diagnostics and analysis over modern fast network protocols
• Safety Integrity Level up to SIL 3
• Optional lockable cabinet to prevent unauthorised operation
