SHF08-227 X.Y Threaded Cartridge Valve
1. Product Overview
SHF08-227 X.Y is an 08-port bidirectional normally-open threaded cartridge valve (X.Y stands for custom variant suffix for fine tuning of flow/structure). It belongs to the mainstream 08-series hydraulic insert valve family, fully interchangeable with HSV/DHF series 08 valves and HP08-00 manual pumps. The valve stays bidirectionally open at power-off and closes both flow paths when energized, widely used for load holding, circuit locking and directional switching in compact mobile hydraulic systems.
SHF08-227 X.Y Threaded Cartridge Valve is a practical Hydraulic valve. As a standard screw-in CARTRIDGE VALVE, it acts as an essential control component inside diverse hydraulic system. This threaded CARTRIDGE VALVE can be directly installed into integrated manifold blocks, simplifying pipeline layout and making the whole hydraulic system more compact and orderly. Designed for fluid on-off control, this Hydraulic valve ensures reliable oil circuit switching to satisfy multiple control requirements of the hydraulic system
2. Core Technical Specifications

Installation Screw-in mounting inside standard 08 valve manifolds
Suffix Note X.Y denotes customized structural/flow calibration parameters
3. Working Principle
Under power-off condition, the internal spring keeps the poppet unsealed to allow unrestricted two-way oil circulation between ports. When the matched solenoid coil is energized, electromagnetic force pushes the spool/poppet to block both inlet and outlet passages, cutting bidirectional flow instantly. Power failure resets the spring to reopen the circuit, delivering fail-safe unlocking performance for machinery.
4. Key Advantages
1. Compact screw-in design saves manifold space for mini hydraulic power packs
2. Fail-safe normally-open structure automatically unlocks the circuit during power loss for equipment safety
3. Universal 08-size interface matches HP08-00 manual pumps and other 08-series cartridge valves for flexible loop assembly
4. Hardened valve core reduces internal leakage and boosts vibration resistance for construction/agricultural sites
5. X.Y suffix supports small-batch customization of flow tolerance and sealing specs for special scenarios
