PVMR, friction detent
The friction detent PVMR allows the directional spool to be held in any position, resulting in infinitely
variable, reversible, pressure compensated flow.
This can be sustained indefinitely without having to continue to hold the mechanical lever. Friction
detent spool position may be affected by high differential actuator flow forces and system vibration
resulting in work function flow reduction.

PVBS, main mpools for flow control (standard)
With post-compensated valves, the A and B work port flow will depend on the pressure drop across the
main spool PVBS.
In open center systems, this pressure drop (standby-pressure) is determined by the volume of fixed pump
flow led to tank across the pressure adjusting spool in the inlet PVPF and the pressure adjusting spool
