HM2 Series Monoblock Directional Hydraulic Metering Valve For Bulldozers

HM2 Series Monoblock Directional Hydraulic Metering Valve For Bulldozers

 

 

Engineered to meet the rigorous demands of dozing operations, the HM2 Series delivers exceptional precision in flow regulation. This purpose-built hydraulic metering valve provides bulldozers with smooth, proportional control over blade movement, enabling fine grading, trenching, and material handling with remarkable accuracy. Trust the rugged HM2 hydraulic valve to master critical functions where incremental adjustment is paramount.

 

 

• Precision Flow Metering Technology:

An advanced spool and sleeve design enables exact flow rate modulation to cylinders or motors, transforming standard directional control into a true hydraulic metering valve. It allows for millimeter-perfect blade positioning and slope control, ensuring every operation meets the highest precision standards.

• Heavy-Duty Monoblock Construction:

A single-piece high-tensile cast iron body withstands extreme shock loads and vibration inherent to bulldozers. The integrated design of the HM2 hydraulic valve eliminates leakage points that are common in sectional valves, enhancing overall reliability.

• Bulldozer-Optimized Dynamics:

Tailored pressure compensation and load-sensing compatibility ensure consistent blade speed under varying loads – a key factor for grading efficiency and operator confidence in every task.

• High-Resolution Control Feel:

Ergonomically designed levers or optional electro-hydraulic pilots offer smooth, low-effort modulation, perfectly matching operator input to blade response for intuitive operation.

• Extreme Pressure & Contamination Resilience:

Hardened spools, reinforced castings, and dual-stage filtration tolerance make this hydraulic metering valve ideal for high-pressure (350+ bar) bulldozer circuits operating in abrasive environments, ensuring long-term stable performance.

• Integrated Pressure Relief & Overload Protection:

Built-in safeguards prevent shock damage during sudden stalls or overloads, extending the service life of components across the hydraulic system and reducing maintenance costs.

 

 

1. Blade Pitch & Angle Control: Fine-grade slopes, backfilling, and contour shaping with precise control.
2. Ripper Shank Depth Modulation: Achieve consistent trenching even in variable soil conditions.
3. Tilt & Lift Circuit Synchronization: Maintain blade attitude during complex maneuvers for seamless operation.

 

 

Simple, compact designed, this valve is only one section for open center and closed center hydraulic systems.

1. Fitted with a main pressure relief valve.

2. Diameter 16 mm - 0.63 in interchangeable spools.

3. Available manual and remote with flexible cables spool control kits.
