Transcription

1 L15 SERIES POST-COMPENSATED SECTIONAL LOAD SENSE VALVE TAKE CONTROL Take control with Muncie Power Products L15 directional control valve. The L15 is constructed with high-grade, iron castings and nickel-plated spools for use in high pressure applications and can be configured with many different spool, control and positioner options. The L15 is designed for flow rates up to 4 GPM (15 LPM), and offers superior performance in a compact package. Muncie Power Products takes pride in supplying the highest quality products along with outstanding service and support. KEY FEATURES High-grade iron castings allow for high pressure capabilities for the most extreme applications Nickel-plated spools resist wear allowing for long life under high pressure conditions TECH SPECS DESIGN TYPE Maximum Work Sections Circuit Types Flow Capacity SECTIONAL 1 Closed center load sense post compensation Nominal: 33 GPM (15 LPM) Maximum: 4 GPM (15 LPM) Tight tolerances and precision machining keep internal spool leakages low Internal oil core design allows for higher flow rates and low pressure drops Load-checks on work sections and inlet relief valves are standard Versatile design can be configured with different spool, control, positioner and accessory options Work sections are pre-assembled and 1% tested prior to shipping Additional options available, lead times may apply.
