ASCO Valve JSF8342G20M Solenoid Valve Direct Acting

ASCO JSF8342G20M Solenoid Valve Direct Acting is a four‑way general‑service valve designed for high‑flow pneumatic control in automation systems, providing reliable actuation with no minimum differential pressure required to shift. Built as a direct‑acting, dual‑solenoid device, it can position and hold a valve state under power with a mechanical detent that preserves the last position if power is removed. The “M” suffix denotes built‑in flow control, which yields a Cv of about 0.44 for the flow‑controlled version and a minimum operating pressure around 0.5 psi. The 8342 family is offered in brass or stainless‑steel bodies to suit varying media and environments, and coil power is typically around 20 W (approximately 20.1 W) for common AC operation such as 120 VAC at 60 Hz. This valve is commonly used in pneumatic circuits for cylinder actuation, pilot control, and general automation tasks, where high flow, robust construction, and the ability to hold position without continuous power are valuable.
