Humphrey 320 & 420 solenoid valve

Humphrey 320 & 420 solenoid valve: powerful high flow in a compact design

The Humphrey 320 and 420 solenoid valve series offers an extremely versatile solution for anyone looking for high flow in a compact housing. These 1/4" direct-acting valves combine low weight with impressive reliability. Inacom supplies this technology to machine builders who need "plug and play" performance for millions of cycles.

Maximum versatility through balanced poppet design

Thanks to the balanced poppet construction, both the 3-weg and the 4-weg types are classified as multifunctional. As a result, they operate reliably over the full pressure spectrum from vacuum to 8,6 bar (125 PSI), regardless of any pressure fluctuations. You can also easily configure the 320-serie as a normally closed, normally open, diverter or selector valve. The 420-serie offers the same flexibility for 4-weg functions or specific three-port configurations by plugging ports.

The highest flow in its class

What makes this series unique is the flow coefficient (Cv) of no less than 1.0. This makes them the highest-flowing valves of their kind. The combination of a fast-switching coil and a short stroke immediately opens a full fluid path with a diameter of 1/4 inch. In addition, the valves are pre-lubricated at the factory, so they last up to 20 million cycles without extra air lubrication.

Flexible mounting and electrical options

The 320 and 420 models are available as standard for inline mounting with 1/4 NPSF ports. For more complex systems, the M420 version also offers the option of manifold mounting on a subbase. This lets you easily stack several valves into one clear block.

• Electrical connection: Fitted with 24-inch lead wires as standard, with options for DIN connectors (code 39) or conduit connections.
• Manual override: Each valve has a non-locking manual override as standard for easy testing.
