The Valve Testing Loop Calibrator is designed to enable users to perform quick, easy tests on HART smart control valves.
Featuring built-in test procedures and an intuitive user interface, the 710 allows users to quickly and easily perform valve tests, while the valve test quick-check results provide at-a-glance diagnostics help you make maintenance decisions faster than ever.
The valve health quick-check results let you know whether your valve is in good, marginal or in bad operating condition so you can quickly decide whether additional maintenance is necessary.
Valve testing and HART communication in a precision loop calibrator.
With the Valve Testing Loop Calibrator’s built in HART communication function, users can source a 4-20 mA signal to cause the smart control valve to move, while simultaneously interpreting the valve’s HART feedback signal to determine whether the valve is moving to the expected position.
In addition to positional information, the measured pressure delivered from the valve’s internal I/P (which moves the valve) can be determined through the HART communication protocol.
