ASCO 821DG004 2 Way Direct Acting Solenoid Valve

ASCO 821DG004 is a two‑way direct‑acting solenoid valve from ASCO’s 821DG product family, designed for electrically actuated on/off control between two ports in automated systems. The model name identifies a specific variant within the series; as with other 821DG devices, it is intended for compact, reliable isolation and flow control in fluid or gas lines where fast actuation is important. In a direct‑acting configuration, the solenoid core moves the valve element directly to open or close the passage, providing simple construction and quick response without the need for pilot pressure. This makes the 821DG004 suitable for space‑constrained installations in control panels, instrument racks, or equipment where a small footprint and straightforward electrical control are priorities. For exact specifications—such as port size, body material, allowable pressure range, temperature limits, electrical connection, and coil voltage—consult the official ASCO datasheet or an authorized distributor listing for 821DG004, since details can vary within the 821DG family. When selecting this model, ensure the coil voltage and electrical interface match your control hardware and verify compatibility with the media and ambient conditions in your system.
