in ED6 electric valves the force generated by a magnetic field fed by an electric coil is transformed into a mechanical action able to command the opening or closing of the valve, allowing or interrupting the flow passage. The ED6 valves are available in NC configuration (valve closed in absence of power supply. Typical application of these valves is the unloading function: a valve fed by current discharges the pumpf flow, preventing movement of the actuators until the interruption of electrical impulse the the passage to tank closes, making the flow available for use. The manual emergency command, for manual opening of the valve in the event of an interruption of the electrical signal, is standard for the valve ED6. The presence of a poppet and a sealing seat allows the ED6 valves to be used as check valves able to support a load thanks to the absence of leakage when closed. A typical example of application in this sense is the block in position and the consent to the descent of a single-acting cylinder. The ED6 valves are double-sealed; the block valve function is possible in both directions of flow. The maximum working pressure for ED6 electric valves is 210 bar (3045 PSI), while its use is recommended with flow rates up to 22l/min. (5,8 USgpm) The ED6 are cartridge valves with SAE8 size and can be installed in a cavity made according to the SAE08/2 standard with 3/4-16 UNF thread. On request the valve bodies are available for the in-line installation of the cartridges. For the electric actuation of the ED6 valves are also available 12V and 24V coils, in direct and alternating current, and the relative connectors.
