The IMI Norgren Model 8494613.8404.23049 is a premier 4-port 2-position (4/2-Way) directional solenoid valve engineered and manufactured in Germany by IMI Norgren (drawing upon advanced fluid technology inherited from IMI Buschjost and IMI Herion). Engineered with an ultra-rugged monolithic body structure weighing approximately 3.75 kg, this industrial-grade control valve is specifically designed for automated production lines, heavy-duty processing machinery, and complex manufacturing networks where fast switching speeds, high flow capacity, and continuous trouble-free duty cycles are required.

The valve features a 4/2-way directional flow configuration with standardized female thread ports G 1/2 and an internal nominal bore diameter of DN12 (12 mm). This large nominal orifice delivers a high flow coefficient (Kv/Cv rating), allowing rapid venting, pressurization, and fluid displacement with minimal internal line throttling or pressure drops. This high flow throughput makes it the premier choice for controlling heavy double-acting pneumatic cylinders and quarter-turn pneumatic rotary valve actuators mounted on process ball valves and butterfly valves across metallurgical furnaces, chemical dosing skids, and automated material handling systems.

The assembly is powered by an advanced industrial electromagnetic coil designated as Coil Code 8404, calibrated for 230V AC operation (covering frequency ranges from 40 to 60 Hz under suffix code .23049). Hermetically molded in high-performance thermoset epoxy resin with Class H thermal insulation, the coil provides exceptional heat dissipation and safeguards against internal electrical burnout under permanent energization (100% continuous duty rating). Electrical termination conforms to the standardized DIN EN 175301-803 connector format, providing IP65 ingress protection against water ingress, industrial washdown sprays, airborne particulates, and cutting oil splashes.

The wetted valve body is precision-machined from corrosion-resistant heavy-duty brass alloy (or high-grade engineered casting), paired with high-resilience NBR/FKM elastomer seals that withstand mechanical wear and aggressive media breakdown. Operating reliably across a broad pressure spectrum from 0 up to 12 bar (0 to 174 psi) without requiring minimum differential pilot pressure, the valve is equally suitable for vacuum circuits and fluctuating low-pressure systems. Rigorous German engineering benchmarks ensure that the IMI Norgren 8494613.8404.23049 delivers millions of switching cycles with zero port leakage, safeguarding factory throughput and drastically minimizing unscheduled downtime.
