Product Overview

The SV10-22-0-N-24DG, SV08-30-0-N-00, SV10-28-0-N-24DG and SV10-28S-0-N-24DG are HydraForce screw-in cartridge valves covering different hydraulic control functions.

These are not simply different voltage versions of the same valve:

• SV10-22-0-N-24DG is a 2-way, 2-position, normally closed poppet solenoid valve for low-leakage blocking and load holding.
• SV08-30-0-N-00 is a 3-port direct-acting spool valve, and the 00 configuration does not include a coil.
• SV10-28-0-N-24DG is a 2-way, normally closed, bi-directional poppet valve designed for low-leakage blocking in both directions.
• SV10-28S-0-N-24DG adds a 100-mesh screen to the SV10-28 hydraulic configuration. HydraForce’s current ordering information identifies S as the 100 Mesh Screen option.

HydraForce technical documentation specifies hardened working components, precision spool or poppet designs, continuous-duty solenoid options and standardized cartridge cavities for these valve families.

Our replacement engineering focuses on cavity compatibility, cartridge dimensions, hydraulic function, electrical configuration and seal matching, followed by 100% simulated operating-condition testing for OEM replacement and aftermarket service.

Key Technical Advantages

1. Hardened Seat for Low Leakage

The SV10-22 uses a hardened seat and is specifically designed for low-leakage blocking and load-holding applications. HydraForce specifies maximum internal leakage of 5 drops/min at 207 bar.

2. Poppet Load-Holding Architecture

When de-energized, the SV10-22 behaves like a check valve, allowing flow from port 1 to port 2 while blocking reverse flow. When energized, the poppet lifts and opens the reverse flow path.

3. Continuous-Duty Solenoid Design

The SV10-22 platform supports continuous-duty coils and efficient wet-armature construction, making it suitable for hydraulic circuits requiring extended energized periods.

4. Compact VC10-2 Cartridge Design

The VC10-2 cavity provides a standardized 10-size, 2-way cartridge installation platform for manifold-integrated hydraulic systems.

5. Hardened Steel Working Components

HydraForce documentation specifies steel construction with hardened working surfaces and zinc-plated exposed surfaces, together with Buna-N O-rings and polyester-elastomer backup elements for the standard configuration.

Application Areas

• Agricultural machinery
• Harvesters
• Mobile hydraulic equipment
• Lifting equipment
• Refuse handling equipment
• Hydraulic manifolds
• Load-holding circuits
• Compact hydraulic power units
• OEM cartridge valve systems

Expert Maintenance Tips

• Confirm the manifold uses the VC10-2 cavity before installation.
• Use 32.5–35.3 N·m as the normal cartridge installation torque range.
• Measure the actual 24 VDC supply at the coil under load.
• Maintain hydraulic cleanliness within the recommended ISO 4406 20/18/14 level.
• When the valve remains closed or fails to release, inspect the poppet, seat and pressure conditions in addition to checking the coil.

HydraForce’s official product documentation defines SV08-30 as a 3-port direct-acting spool valve, rated to 207 bar and installed in a VC08-3 cavity.

Key Technical Advantages

1. Direct-Acting Spool Architecture

SV08-30 uses direct electromagnetic spool actuation, providing a short control chain and compact three-port switching architecture.

2. Fully Guided Precision Spool

The HydraForce design uses a hardened precision spool and cage and a fully guided spool arrangement, supporting long service life under repeated switching.

3. Compact VC08-3 Installation

The VC08-3 cavity allows the valve to be integrated directly into a hydraulic manifold, reducing external plumbing and potential leak points.

4. Flexible Pressure Capability

HydraForce specifies that all ports may be fully pressurized. However, Port 1 is not intended to be used as the inlet, so the hydraulic symbol and specified flow paths must be followed during system design.

Application Areas

• Mobile hydraulic manifolds
• Construction equipment
• Paving equipment
• Auxiliary hydraulic circuits
• Directional switching circuits
• Agricultural machinery
• Industrial hydraulic systems
• Compact valve blocks

Expert Maintenance Tips

• 00 means no coil in the supplied configuration.
• Verify the VC08-3 cavity before installation.
• Use 25.8–28.5 N·m cartridge installation torque.
• Follow the specified port function and hydraulic symbol when plumbing.
• Maintain approximately ISO 4406 18/16/13 hydraulic cleanliness.
• Select an appropriate 08-size D/E coil if the cartridge is intended to be converted to a complete solenoid valve assembly.

HydraForce’s current SV10-28 documentation specifies the 241 bar pressure rating, 2.8 bar minimum differential pressure, 2.8 L/min reseat flow, 5 drops/min maximum leakage, VC10-2 cavity and 0.15 kg unit weight.

Key Technical Advantages

1. Bi-Directional Blocking

The SV10-28 is specifically designed for bi-directional low-leakage blocking and load holding, unlike unidirectional poppet/check arrangements.

2. Hardened Poppet and Seat

The hardened working seat and poppet architecture improve resistance to repeated cycling and help maintain low internal leakage.

3. Controlled Reseat Requirements

The valve specifies a 2.8 L/min reseat flow and 2.8 bar minimum differential pressure, making differential-pressure conditions an important part of engineering selection.

4. Continuous-Duty Solenoid Platform

The SV10-28 platform supports continuous-duty coil configurations. The 24DG model uses a 24 VDC D-Coil with DIN 43650 connection.

Application Areas

• Load-holding manifolds
• Mobile cranes
• Lifting equipment
• Construction machinery
• Agricultural machinery
• Hydraulic cylinders
• Hydraulic manifolds
• Compact hydraulic power units

HydraForce’s ordering information identifies S as a 100 Mesh Screen option for the SV10-28 family, while the remaining performance data follows the SV10-28 platform.

Key Technical Advantages

1. Integrated 100-Mesh Screen

The S option adds a 100-mesh screen to provide local particle protection at the cartridge. This can be valuable in manifolds where there is increased risk of residual assembly contamination or upstream debris.

2. Bi-Directional Load-Holding Function

SV10-28S retains the fundamental 2-way normally closed, bi-directional blocking architecture of the SV10-28 family.

3. Low Leakage Poppet Design

The SV10-28 family specifies a maximum internal leakage of 5 drops/min at 207 bar, making it suitable for applications where hydraulic drift must be controlled.

4. Standard VC10-2 Cavity

The screened configuration remains compatible with the standardized VC10-2 cartridge platform, enabling manifold integration.

Application Areas

• Load-holding manifolds
• Mobile cranes
• Aerial work platforms
• Agricultural machinery
• Construction equipment
• Hydraulic cylinder isolation
• Compact power units
• Mobile hydraulics operating in contaminated environments
• OEM manifold assemblies

Expert Maintenance Tips

• Consider the 100-mesh screen as part of the hydraulic flow path because a contaminated screen can increase local pressure drop.
• Inspect the screen when valve response becomes slow or differential pressure rises unexpectedly.
• Maintain the system-level filtration program; the integrated screen is not a substitute for proper hydraulic filtration.
• Verify VC10-2 cavity condition before installation.
• Follow the specified cartridge and coil-nut torque ranges.
