1/4 in NAMUR Brass Solenoid Valve

This 4-way NAMUR-mount solenoid valve is built for pneumatic automation and fluid-control systems that require a compact 1/4-inch pipe connection. It suits engineers and maintenance teams specifying direct-acting valves for air or inert-gas circuits.

Brass body with NBR seals for 150 psi air service

The brass body and NBR seals handle a maximum operating pressure differential of 150 psi for air or inert gas, while the .09 Cv orifice meters flow precisely. The coil enclosure is watertight and supplied without a junction box, so the installer provides the final electrical connection and conduit.

120V AC coil voltage with Prop 65 notice

The valve operates on 110V AC or 120V AC supply, simplifying integration into standard North American control panels. California Proposition 65 warnings apply because the product contains chemicals identified by the state as causing cancer and reproductive harm.
