PRESSURE COMPENSATOR - RESTRICTIVE (PRE-COMPENSATION)

Mechanical Pressure Control Valves
Pressure Compensator
Restrictive (Pre-Compensation)
The valve with an orfice beyond port (3) and sensed by port (1) maintains a constant flow rate from (3) regardless of load pressue changes in the system downstream of (3), or in the inlet at (2) as long as pressure at (3) is above (1) by more than spring setting chosen and pump supply is in excess of demand
The valve's spool maintains a constant differential pressure across an external orifice, thereby regulating the hydraulic flow rate across this external orifice
When used with an orfice as described above, it functions as a restrictive type regulator, delivering pump flow through the external orifice
All ports may be fully pressurized
or The valve allows pressure compensated flow from (2) to (3) regulated by the pressure present at (1)
Pressure differential between (3) and (1) is fixed at 8/14/18/24 bar
These are minimum values, increasing with the flow because of the pressure drop through the valve
When used with (1) connected to a drain line, it works as a fix setting pressure reducing valve
