EV30 cartridge electric valve 2/2 pilot acting bidirectional SAE10

In EV30 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 EV30 valves are available in NC configuration (valve closed in absence of power supply) or NO (valve open in absence of power supply). Once open, the valves EV30 allow the flow in both directions. Typical application of these valves is the unloading function: a normally open valve discharges the pumpf flow, preventing movement of the actuators until an electrical impulse closes the passage to tank, making the flow available for use. For the NC version an emergency command is also available for manual opening of the valve in the event of an interruption of the electrical signal. The presence of a poppet and a sealing seat allows the EV30 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 EV30 valves are single-sealed; the block valve function is only possible in one direction while in the opposite direction the flow passage is free. The maximum working pressure for EV30 electric valves is 350 bar, while its use is recommended with flow rates up to 70 l/min. The EV30 are cartridge dimensioned to be installed in cavities made according to the SAE10/2 standard with 7/8-14 UNF thread. On request the valve bodies are available for the in-line installation of the cartridges. For the electric actuation of the EV30 valves are also available 12V and 24V coils, in direct and alternating current, and the related connectors.
