The ePVC Standalone Pressure / Volume Controllers provide independent control of hydraulic pressure or flow for a variety of applications. These controllers are electromechanical and only require standard 100‐240 VAC, 50/60 Hz power for operation ‐ no hydraulic power is needed!


The ePVC is capable of closed‐loop servo‐control of the pressure or volume. It features a large volume capacity and stroke with a direct, integrated transducer for precise volume measurements to prevent control errors caused by gear backlash commonly found in other systems that use a motor encoder.


The ePVC is ideal for the control of confining pressure in triaxial test, head pressure in permeability tests, fluid pressure in hydro‐fracture tests, or even the axial load in long‐term creep tests. It can also be used to measure flow in permeability tests or measure volume change in triaxial tests while applying the prescribed pressures.


The ePVC includes interface programs for PC or mobile devices (iOS, Android and Windows) to remotely set pressures or flow rates. Multiple units can be linked through our CATS software for simultaneous control as required by triaxial, hydro‐fracturing, creep, and other testing applications.
