ASCO 8342C21 Two Way Direct Acting Solenoid Valve

ASCO 8342C21 is a four‑way general‑service direct‑acting solenoid valve from ASCO’s 8342/342 family, designed for high‑flow control of compressed air and inert gases in analytic and diagnostic equipment, heating systems, dust‑collection setups, and refining processes. It operates without a minimum differential pressure to shift and is available with single or dual solenoids, with the 120 VAC coil variant commonly used for rapid actuation at 60 Hz. The valve body is typically offered in brass or stainless steel, and port configurations commonly include 1/4" to 3/8" pipe connections, featuring one pressure inlet, two cylinder ports, and one or two exhaust ports in the four‑way arrangement. Rated for ambient temperatures roughly 32°F to 125°F (0°C to 52°C) and with coil insulation class F, it supports reliable operation in standard industrial environments, and it can be mounted in any position. The high‑flow, slide‑style design delivers robust actuation and long service life, making it a suitable choice for analytical and diagnostic platforms, industrial process control, and equipment requiring precise, rapid valve cycling.
