12. P-1NN 4-way Pressure Control
Typically this control is used where very fast response is required.
Response times of milliseconds
Set works in sawmills

15. P-1NN/G HP Limiting & Load Sensing

18. Meter-Out Style Controls

19. Meter-Out Style Controls
The meter-out style of control a generally used in circuits, that require quick reaction to small load changes.
While overall response time is slower than the PVG pump, the PVM will begin to react as soon as there is a change in the system.

20. Features of the Meter-Out Control
Simple in Design
Compensator uses a 10-2 cavity relief valve.
Easily field repairable
Easily field convertible
Easily field tuned in the field
Quick response
