S81 Directional control valve
SP81 hydraulic multi-way control valve (special for log splitter)
Main purpose
1. directionally control that flow direction of the hydraulic oil, and specially controlling the whole set of action of stretching out, splitting, retracting and reset of the oil cylinder of the log splitter, which is the main control valve of the log splitter;
2. It is equipped with a built-in overflow valve to limit the maximum pressure of the system and prevent overload from damaging the oil pump, oil cylinder and oil pipe;
3. a pressure automatic trip and clamping structure is configure, and that valve core automatically returns after the wood splitting is in place and the pressure reach the standard, so that the handle does not need to be manually broken back;
4. High and low flow switching design, no-load rapid retraction to improve operation efficiency, heavy load and large torque splitting stable output;
5. The integrated valve body structure is suitable for the oil circuit of the single wood splitter, and directly matches the single-stage hydraulic pump to simplify the layout of the oil circuit.
Core advantages
1. that structure is durable and has strong adaptability to work conditions; The integral casting valve body has high strength, the valve core has hard chromium plating, is wear-resistant and impurity-resistant, is not easy to be stuck in the harsh environment of sawdust and dust in the field, and has low long-term heavy load failure rate.
2. Automatic unloading saves time and effort When the pressure of splitting wood reaches the set value, it will automatically trip and reset, and the operator does not need to press the handle continuously, which greatly reduces the labor intensity.
3. Pressure adjustable to protect the whole machine Built-in overflow pressure 70 – 140 bar adjustable, accurately match different wood hardness, overload automatic pressure relief, to prevent cylinder dead, oil pipe burst, pump body burning.
4. efficient operation of flow adaptation The rated large flow supports no-load rapid retraction, stable flow and pressure in the wood splitting stage, uniform splitting speed and higher single cycle efficiency.
5. Simple installation and maintenance Integral
