Product Description

Product Description

 

Discover our innovative hydraulic support auxiliary valves, meticulously crafted to meet the most demanding technical specifications. These valves exemplify superior engineering excellence, ensuring optimal performance and reliability in hydraulic roof support systems.

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).
