Product Overview
QDS Bolter Hydraulic Valves are specialized hydraulic valve components applied in QDS (Quick Disconnect System) Bolter equipment, commonly used in Australian underground coal mines for roof bolting and secondary support operations.
Hydraulic Valves for QDS Bolter Applications
QDS Bolters operate under high-cycle, high-load, and harsh underground conditions. The hydraulic valve system is a critical element that directly influences drilling performance, bolting efficiency, equipment reliability, and operational safety.
Whether you are drilling through hard rock or installing roof bolts in challenging strata, our integrated valve solutions provide the smooth, responsive control your operators need.
Hydraulic Control Requirements in QDS Bolter Applications
- Stable Drilling Thrust and Speed Control
Hydraulic valves regulate drilling force and feed speed to adapt to varying geological conditions. - Precise Sequencing and Pressure Control
Valves manage drilling, resin injection, and bolt installation sequences for consistent operation. - Coordinated Rotation and Feed Control
Directional and proportional valves ensure smooth motion and reduce mechanical stress.
Core Technical Features for QDS Bolter Hydraulic Valves
Precision Proportional Control
Enables operators to finely adjust drilling speed and feed force, helping prevent drill jamming, improving control stability, and extending drill bit service life during bolting operations.
Load-Sensing Technology
Supplies hydraulic flow strictly according to actual load demand, reducing unnecessary energy loss and system heat generation, while improving overall machine efficiency and fuel economy.
Pressure Management
Dedicated control for Stab Jacks and Mesh Jacks. Prevents roof damage while providing maximum platform stability.
Integrated Safety Functions
Integrated master dump valves and hydraulic locking functions enable controlled pressure release and actuator stability, supporting compliance with underground coal mining safety practices such as MDG 35.1.
