Overview
The Asco EF8342G1 (model EF8342G001-240) is a 4-way direct-acting solenoid valve from the Red Hat II series. Built with a brass body and 1/4 inch NPT threaded connections (FNPT × FNPT), this valve is engineered for pneumatic and general service applications where reliable flow control is critical. The EF8342G1 requires no minimum operating pressure or flow to operate, making it ideal for on-off control in air, water, and light oil systems.
