Technical Data Table
Working Pressure: Rated up to 500 Bar (7250 PSI).
Material Choice: Premium 20CrMo Alloy Steel with anti-rust plating.
Seal Material: High-temperature resistant Fluorine rubber (Viton) or reinforced NBR.
Connection: Free-welding flange type for “Plug-and-Play” installation.
Applicable Tonnage: Suitable for mini excavators (0.8t-6t) to heavy-duty machines (60t).
Key Features & Benefits
Vibration Resistance: Unlike standard industrial valves, our breaker stop valves are built to withstand the intense hydraulic pulses generated by rock hammers.
Free-welding Convenience: The flange-type design eliminates the risk of welding slag entering the hydraulic system, protecting your excavator’s main pump and valves.
High-Temperature Stability: Ideal for high-intensity mining operations in hot climates (e.g., Saudi Arabia, Paraguay), ensuring stable performance without seal degradation.
Installation & Maintenance Guide
Positioning: Install at the termination point of the auxiliary piping on the excavator arm.
Operation: Always double-check that the valve is fully open during breaker operation to prevent excessive back-pressure.
Maintenance: Regularly inspect for handle tightness and external leaks to ensure safety and system efficiency.
Upgrade your excavator piping with our high-temperature, high-pressure cut-off valves. 100% compatible with CAT, Komatsu, and Sany. Rated for 500 Bar.
