Four Way Solenoid Valve Working Principle

When energized, the coil around the core pulls it away from the pilot base, which allows airflow into the pilot itself. This pushes the pilot against the spool, shifting the valve''s airflow as long as the coil is energized.. When resetting, the core spring pushes it against the pilot to seal off airflow and also open the pilot''s exhaust ports, which let the pilot reset to its idle position.

Understanding the Working Principle of Hydraulic Accumulators

When the hydraulic fluid is released, the gas expands, pushing the fluid out through an outlet valve. This working principle allows the accumulator to provide a continuous and reliable source of hydraulic power. It can absorb pressure fluctuations and dampen hydraulic shocks, enhancing the stability and efficiency of a hydraulic system.
