A working, fluid process system allowing for hands-on training relating to the design, calibration, and testing of common control valves used in industry. The device includes, provision for mounting control valves of different designs, including diaphragm-type valves, by a variety of manufacturers.

A magnetic flow meter and two pressure sensors are provided in order to demonstrate performance at different flow rates, using multiple valve plug and trim designs. Field calibration of valves and positioners can be accomplished, using a high-quality regulator and test gauge.

With optional and/or user-supplied equipment the device can be used to create basic process loops incorporating flow control.
Welded steel frame workstation, using 14-gauge, 1-1/2" x 1-1/2" tube, and incorporating two, 14-gauge support shelves.
Four casters, two with locks.
Power/meter module including 19" rack panel, enclosure, and 16-gauge steel support structure.
Panel-mounted components, including two digital pressure displays, digital flow display, pilot light, on/off switch, pump control with provision for external control via relays, GFI circuit protection, fuses, test gauge (0-30 psig), precision regulator, quick-connect air fittings, and electrical service outlets.
Enclosure-mounted, supplemental, 4-20 mA, flow meter connections.
Service air regulator and quick disconnects.
