Product Description

Product Description

 

Innovative hydraulic support auxiliary valves crafted from leading-edge technical insights:

Category	Working Principle	Model Types	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.	- Compliance: Meets mining safety standards (e.g., ATEX/Ex d I Mb explosion-proofing).
	- Leakage rate ≤0.1% under rated pressure.	- Flow Capacity: 20-200 L/min (varies by model).
