G040-123 Portable Valve Checker

The G040-123 is derived from the M040-120 P/Q Valve Tester. It provides field checking of the complete range of Moog electrical feedback (e.f.b.) valves, both proportional and servo, that have spool position control (Q) only. For valves with spool position (Q) and pressure control (P), use M040-120.

It is connected “in-line” between the plant electronics and the valve so checking of the valve is made without removing it from the plant, so that hydraulic and electronic problems can be isolated. The checker operates in two modes: “Checker” and “Plant”.
