PDVV (+) Valves

Momentary, push button actuated, poppet valves that admit air drive
pressure to the PDVV actuator causing the PDVV plunger to move
forward, compressing oil and increasing the test pressure. Used to
increase pressure and for fine pressure adjustment.

PDVV (-) Valves

Momentary, push button actuated, poppet valves that release air drive
pressure from the PDVV actuator causing the PDVV plunger to move
back, decompressing oil and decreasing the test pressure. Used to
decrease pressure and for fine pressure adjustment.

PDVV DRIVE Gauge

Analog gauge that indicates the PDVV actuator air pressure and the
approximate corresponding oil test pressure.

PUMP DRIVE Gauge

Analog gauge that indicates the pump drive air pressure and the
approximate corresponding pump oil output pressure.

Test Pressure

The oil pressure in the OPG1 PDVV, at its TEST connections and in the
system to which the OPG1 is connected.
