Product Description
hydraulic support auxiliary valves based on the technical details provided:
• Material: stainless steel
• Accuracy: 25/40/80μm
• The filter element is an important part of the filter. It filters the emulsion entering the hydraulic support, prevents the hydraulic valve from being blocked by impurities, and ensures the normal operation of the hydraulic system. The filter element is a vulnerable part, so it should be cleaned and replaced regularly

Material & Characteristics |
| Function |
- Pressure Regulation: Uses relief valves to maintain system pressure (16-50 MPa). |
- Standard Model: Basic pressure/flow control for general support actions. |
- Valve Body: Stainless steel or cast iron (corrosion resistance, high strength). |
| |
- Flow Control: Adjusts flow via throttle valves for actuator speed modulation. |
- High-Pressure Model: Optimized for 40-50 MPa systems in heavy-duty tasks. |
- Valve Spool: Hardened alloy steel (wear resistance, durability under abrasive conditions). |
| |
- Directional Control: Electromagnetic/manual valves switch fluid paths. |
- Intelligent Model: Integrated with sensors for automated electrohydraulic systems. |
- Seals: Nitrile rubber or polyurethane (high-temperature and chemical resistance). |
| |
- Safety Protection: Check valves prevent reverse flow; relief valves limit overpressure. |
- Compact Model: Lightweight design for narrow or inclined mining spaces. |
- Springs: Chrome silicon steel (fatigue resistance, stable elasticity). |
| Key Features |
- Modular design for quick maintenance. |
- Application-Specific Models: Customized for roof adjustment, conveyor shifting, etc. |
- Filter Elements: Stainless steel mesh (blocks particulates ≥25 μm). |
| |
- Compatible with fire-resistant hydraulic fluids (e.g., water-glycol emulsions). |
|
- Coating: Anti-corrosion coatings (zinc-nickel plating) for humid/acidic environments. |
| Performance |
- Rapid response (≤0.1s actuation time). |
- Pressure Range: 16-50 MPa. |
