SL-PCB Pressure Compensating Regulator Valve
DESCRIPTION
16 size, 1 5/16-12 thread, “Super” series, pressure compensating regulator valve.
OPERATION
The SL-PCB-0P with an orifice between ports (3) and (1) maintains a constant flow rate from (3) regardless
of load pressure changes in the system upstream of (3), or in the bypass leg at (2) as long as pressure at
(2) is less than (1).
The valve's spool maintains a constant differential pressure across a internal orifice, thereby regulating the
hydraulic flow rate from across this external orifice. (see options table for pressure ranges)
When used with an orifice as described above, it functions as a priority type regulator, delivering pump flow
first to the external orifice, then bypassing excess to (2). All ports may be fully pressurized.
The SL-PCB-0V with a dump valve and a pilot relief valve at (1) acts as main stage of a ventable relief
valve.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
HYDRAULIC SYMBOL
Can be used as a logic element.
SL-PCB-0P is commonly used as a bypass flow regulator (100
PSI recommended).
SL-PCB-0V is commonly used as the main stage of a ventable
relief valve (50 and 100 PSI recommended).
