The SLEVM22B4 is a direct-operated 2-way cartridge solenoid valve from Taon Hydraulik Komponenter ApS of Denmark. Cartridge valves — also known as screw-in or slip-in valves — thread directly into a machined manifold cavity, eliminating the external piping, fittings, and leak points associated with inline valve bodies. The SLEVM22B4 is configured normally open, meaning the valve passes flow when de-energised and closes when the solenoid is powered. This NO configuration is commonly specified for safety-related hydraulic functions — such as maintaining flow to a brake release or a pilot supply — where loss of electrical power must not interrupt the hydraulic circuit.

Why choose a cartridge valve over an inline body?

Cartridge valves integrate the entire valve function — solenoid, poppet or spool, and seat — into a single threaded insert. This reduces the installed envelope compared to a traditional body-ported valve and simplifies manifold design. In mobile hydraulics (construction equipment, agricultural machinery, material handling) and compact industrial power units, cartridge valves allow multiple functions — directional control, pressure relief, flow regulation, and solenoid shutoff — to coexist in a single custom manifold block. The threaded interface also simplifies field replacement: unscrew the cartridge, install a new one, with no need to disconnect pipework or disturb adjacent valves.
