DHF12 220 00 Threaded Cartridge Valve
Product Overview
DHF10‑231 is a 10‑size spool‑type threaded cartridge solenoid valve widely used in hydraulic system. It adopts standard 10‑port screw‑in installation form, fitted with manual override knob for manual commissioning and emergency operation. This valve realizes on‑off control of hydraulic oil circuit by solenoid driving spool movement, commonly applied for hydraulic power units, lifting equipment, engineering machinery auxiliary hydraulic loops.
DHF10‑231 Threaded Cartridge Valve is a high-performance electromagnetic switching Hydraulic valve. As a screw-in CARTRIDGE VALVE, it serves as a core automatic control component for diversified hydraulic system. This threaded CARTRIDGE VALVE can be directly installed into integrated manifold blocks, removing scattered external pipelines and simplifying structural layout to make the whole hydraulic system compact and orderly. Responding to electrical control signals, this Hydraulic valve completes fast switch of hydraulic oil circuits to satisfy automatic control demands of industrial equipment and mobile machinery hydraulic system.

Working Principle
1. De‑energized state: The reset spring keeps the spool in its home position to maintain the original channel status.
2. Energized state: Solenoid generates electromagnetic force to push spool for displacement, switching the internal oil passage and completing circuit opening‑closing action.
3. Manual override function: Red manual knob on valve top can mechanically drive spool movement for debugging or power‑failure emergency operation; it will auto‑reset after release.
4. Power‑off, reset spring pushes spool back to initial working position.
Core Advantages
1. Standard 10‑size cartridge dimension, compatible with mainstream 10‑series manifold block cavities on market.
2. Equipped with manual override knob, convenient for on‑site commissioning, testing and emergency handling.
3. Replaceable independent coil, maintenance without taking out the whole valve cartridge from manifold block.
4. Compact screw‑in cartridge structure, save installation space and simplify hydraulic system piping layout.
5. Precision‑ground spool‑sleeve matching, low internal leakage and stable volumetric efficiency under continuous working conditions.
Application Scope
Hydraulic power packs, aerial work platforms, small construction machinery, agricultural machinery, fixture hydraulic control circuits, general‑purpose industrial hydraulic on‑off control system.
