Deltrol 10120-66 Hydraulic Inline Needle Valve

DELTROL 10120-66 EN25S hydraulic inline needle valve with knurl knob. This inline hydraulic valve provides manual, fine flow control by a tapered needle that seats against a matching seat, enabling incremental adjustments in-line in hydraulic circuits. The knurl knob is designed for reliable grip and precise tuning, making it straightforward to dial in a desired flow rate during setup or calibration. Identified by the 10120-66 part number, this unit is part of Deltrol’s EN25S family of inline needle valves, offering an inline configuration for direct integration into hydraulic lines. In practice, needle valves are used to isolate or fine-tune flow with repeatable settings, with adjustment performed by turning the knob to increase or decrease flow as system conditions require. This description reflects the product type and core feature set: a Deltrol inline needle valve with a knurl knob, designed to provide precise manual control directly in the hydraulic line.
