ASCO EF8340A1 Solenoid Valve

ASCO EF8340A1 is a single, four‑way, direct‑acting solenoid valve from ASCO’s Series 8340 line, engineered for air service and the precise control of pneumatic cylinders. It uses 1/4 in NPT air ports for supply and exhaust and is rated for up to 150 psi inlet pressure, making it suitable for compact, high‑speed actuation on automation and packaging lines. The EF prefix denotes an explosion‑protected variant intended for enclosure types that require enhanced protection (such as 3, 4, and 7), enabling installation in more demanding environments while maintaining reliable operation. As a four‑way valve, it can route compressed air to either side of a double‑acting cylinder while venting the opposite side to exhaust, enabling reversible cylinder motion and synchronized actuation in control panels, machine tools, and material‑handling systems. This catalog number identifies a single valve unit (not a manifold) with maximum ambient and fluid temperatures around 130°F (54°C); electrical coil options and voltages follow the broader 8340 family lineup and can vary by configuration. Applications include automation equipment, packaging lines, clamping fixtures, and other pneumatic control tasks where a compact, robust air valve is required.
