The frequency control valve is the central nervous system of a hydraulic breaker’s energy output. By regulating the hydraulic flow into the piston chamber, this valve allows the operator to switch between Long Stroke (Maximum Impact Energy) for heavy demolition and Short Stroke (Maximum BPM) for high-speed material scaling. Our valves are machined to micron-level tolerances to ensure zero internal leakage even at 180 Bar working pressure.
Basalt & Hard Granite: Set to Long Stroke. Higher impact energy is required to initiate micro-fractures in high-density rock.
Soft Limestone & Concrete: Set to Short Stroke. Increasing the Blows Per Minute (BPM) significantly improves production rates where massive force isn’t required.
Secondary Breaking: A medium setting is recommended to prevent “blank firing,” which protects the through bolts and front head from fatigue.
Troubleshooting & Maintenance
Problem: Impact speed does not change when turning the valve. Diagnosis: Likely internal bypass due to contaminated hydraulic oil causing scratches on the valve spool. Inspect the O-rings and ensure the hydraulic filter is changed according to the 500-hour service interval.
