Product Overview
The WSM08130D-01M-C-N-24DG (Material Number 3229161) is a classic model in the HYDAC WSM08130D series of 3/2 solenoid directional poppet valves. Featuring metric cartridge construction compatible with the 08130 standard cavity, this direct-acting poppet type, normally open valve provides 3-way, 2-position directional control.
The valve is designed to control the start, stop, and direction of fluid flow in hydraulic systems for mobile and industrial applications. The valve body is constructed from high tensile free-cutting steel with hardened and ground poppet components, and all external surfaces are zinc-plated for corrosion resistance. The valve is leakage-free (max. 5 drops/min).
As an original HYDAC solenoid cartridge valve, this product offers complete interchangeability within the same series and cavity, requiring no modifications to manifold designs.

Key Technical Advantages
1. Direct-Acting Poppet Construction — Leakage-Free Sealing
The WSM08130D-01M-C-N-24DG features direct-acting poppet construction—in the closed position, the poppet achieves metal-to-metal sealing against the seat. Unlike spool-type valves, the poppet design delivers leakage-free performance, with maximum leakage of only 5 drops/min (0.25 cm³/min) at 350 bar, making it ideal for applications requiring long-term actuator position holding.
2. Wet-Type Solenoid Design for Quiet, Long-Life Operation
Features an oil-immersed solenoid armature design—the movable iron core operates fully submerged in hydraulic oil. The hydraulic oil lubricates moving parts to reduce wear and cushions switching impact and vibration. This ensures extended service life and extremely low noise levels. Coils can be replaced without opening the hydraulic system. The HYDAC high-performance solenoid delivers excellent switching performance.
3. Hardened and Ground Poppet for Superior Wear Resistance
The poppet is hardened and precision ground. High-precision machining of critical control elements ensures long-term sealing performance and extremely low internal leakage, significantly extending valve service life.
4. 350 bar High Pressure and 22 L/min Flow Capacity
Delivers 350 bar maximum operating pressure and 22 L/min maximum flow in a compact Size 8 cartridge package. Rated flow covers a broad 0–22 L/min range, suitable for precise directional control in diverse medium-to-high pressure hydraulic systems.
5. Compact Cartridge Design for Space-Saving Installation
The metric cartridge construction enables direct installation in connection housings and control blocks for space-saving installation. The compact design significantly reduces external tubing and fittings, minimizing leakage risk and installation space requirements.
6. Superior Corrosion Resistance and Protection
All exposed surfaces are zinc-plated. Built-in coil seals effectively prevent moisture ingress into the solenoid system. Media temperature range covers -20°C to +100°C, suitable for diverse extreme climate conditions and high-temperature hydraulic systems.
7. Manual Override for System Safety
Equipped with manual override (Push Override) . In case of power failure or emergency, the valve can be manually actuated for emergency directional control, ensuring system safety.

Expert Maintenance Tips
1. Installation Guidelines
Thoroughly clean the cavity (08130 cavity) and valve exterior before installation to prevent foreign particles from entering and causing seal damage or spool sticking.
Follow HYDAC specifications for installation torque to ensure proper valve seating.
No orientation restrictions—any installation orientation is acceptable based on manifold design requirements.
Cartridge valves can be installed directly in connection housings and control blocks without external piping.
Threaded cavity specification: M20×1.5_08130.
2. Hydraulic Fluid Cleanliness
Recommended fluid cleanliness: ISO 4406 21/19/16 or better.
Use hydraulic oil meeting DIN 51524 Parts 1 and 2.
Viscosity range: 7.4–420 mm²/s.
Media temperature range: -20°C to +100°C.
3. Electrical Connection Specifications
WSM08130D-01M-C-N-24DG uses 24V DC supply with nominal current of 1.13 A (@ 20°C).
Voltage tolerance: ±15%.
Connector type: DIN EN 175301-803 standard.
Coils are rated for 100% continuous duty (ED) , capable of operating at 115% of nominal voltage at 60°C ambient.
For AC supply, select coils with built-in bridge rectifier.
4. Normally Open Function Considerations
WSM08130D-01 allows bidirectional free flow when de-energized (normally open characteristic).
The valve switches to the working position when energized.
This normally open / energized switching function characteristic should be carefully considered during system design.
5. Seal Material Selection
6. Periodic Maintenance Inspection
Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.
Check electrical connectors for looseness, oxidation, or moisture ingress.
Solenoid coils can be replaced quickly without opening the hydraulic system.
If response lag or unstable shifting is observed, first check system fluid cleanliness and poppet seal condition.
