ASCO EF8210B56 Solenoid Valve

ASCO EF8210B56 solenoid valve is a two‑way, normally closed valve from the ASCO 8210 General Service family, designed for internal pilot operation and reliable shutoff in compressed‑air and inert‑gas lines. It uses 1‑1/2" NPT ports and supports a control range of 0–150 psi for air/gas service, making it suitable for pneumatic automation, process lines, and general plant utility circuits. The EF8210B56 designation covers a family variant offered with multiple coil voltages to fit common control panels, including 24 V DC (EF8210B56‑24VDC) and AC coils such as 120 VAC/60 Hz or 208 VAC/60 Hz, enabling compatibility with standard electrical systems. As a normally closed, internally piloted valve, it opens when energized and returns to a sealed position when de‑energized, with ASCO’s robust construction designed for repeated cycling in industrial environments. Typical applications include isolating or sequencing air lines, gas‑handling segments, and general process-control loops where 1‑1/2" piping is standard and tight shutoff with quick response is required.
