ASCO Numatics Emerson Electric 8340A3 Solenoid Valve

The ASCO Numatics Emerson 8340A3 Solenoid Valve is a four-way, two-position, 4/2 universal operation valve in the ASCO Series 340 (8340) line, designed for air-only cylinder control. It provides 1/4-inch NPT porting with four ports (supply, valve output, and two exhausts) and can be installed as a single valve or in group-mounted arrays for compact or centralized pneumatic control in automation lines. The 8340A3 designation maps to the A003 coil variant, offering dual coils compatible with 120 VAC at 60 Hz or 110 VAC at 50 Hz operation. As a direct-acting valve, it delivers fast actuation for reliable cylinder control in a wide range of industrial applications, including automated manufacturing, packaging, and material handling equipment. Typical mounting configurations support both standalone use and group-mount installations in distributed control schemes across manufacturing floors.
