4 4484 Boeing Drive - Rockford, IL 6119 SL-PLA Super Series, Logic Valve DESCRIPTION 16 size, 1 /16-12 thread, Super series, logic valve OPERATION The SL-PLA 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). Used for basic blocking applications. HYDRAULIC SYMBOL FEATURES Hardened parts for long life. Industry common cavity. For bidirectional applications see SL-PLC. For metering see SL- PCA or SL-PCB.
