DHF08S‑34M‑00 Threaded Cartridge Valve
DHF10 221 00 Threaded Cartridge Valve
DHF10 227L D Threaded Cartridge Valve
Product Overview
DHF08S‑34M‑00 is a double‑solenoid spool‑type threaded cartridge valve for hydraulic system. It adopts standard 08 size screw‑in installation, two electromagnetic coils for bi‑directional spool driving, achieving multi‑position circuit switching control inside hydraulic manifold block. Widely applied on hydraulic power units, engineering machinery, material‑handling equipment and automation hydraulic facilities.
DHF08S‑34M‑00 Threaded Cartridge Valve is a high-performance electromagnetic control Hydraulic valve. As a screw-in CARTRIDGE VALVE, it serves as a critical automatic control component in the hydraulic system. This threaded CARTRIDGE VALVE can be directly screwed into integrated manifold blocks, removing cumbersome external pipelines and simplifying structural arrangement to make the whole hydraulic system compact and simplified. Responding to electrical command signals, this Hydraulic valve realizes rapid switching of hydraulic oil circuits, satisfying diversified automatic control demands for mobile machinery and industrial equipment hydraulic system.

Working Principle
1. De‑energized condition: Both solenoid coils are power‑off. Centering springs keep the spool at neutral middle position, maintaining the neutral port connection of hydraulic circuit.
2. Left coil energized: Electromagnetic force pushes spool to one side, switches internal oil passages and completes one‑direction commutation action.
3. Right coil energized: Spool moves to opposite position, realizes reverse oil‑circuit switching.
4. After cutting off power supply, centering springs automatically return spool back to neutral position.
Core Advantages
1. Standard 08‑size cartridge profile, fits common 08 manifold cavities without modification.
2. Double‑solenoid control, reliable bi‑directional reversing performance, low pressure drop under rated flow.
3. Two independent replaceable coils, convenient maintenance without removing the whole valve cartridge from manifold block.
4. Compact screw‑in structure, saves space, simplifies piping layout for integrated hydraulic system.
5. Stable spool‑centering spring mechanism, accurate neutral‑position reset.
Application Scope
Hydraulic power packs, small construction machinery, lifting equipment, agricultural machinery, fixture hydraulic control loops, special‑purpose hydraulic machines, used for multi‑way directional control of hydraulic system.
