The OS-MV-2218-30 is a direct-operated 2/2-way normally closed solenoid valve from Sommer-Technik, purpose-designed for integrating a second oil lubrication circuit into hydraulic and lubrication systems. The brass body and 2 mm orifice are optimised for oil media, with the valve opening when energised to admit the secondary oil circuit and closing positively when de-energised. With a maximum operating pressure of 40 bar and media temperature tolerance from −10°C to +95°C, the valve suits a broad range of machine tool, industrial gearbox, and automatic lubrication applications.

How does the valve integrate into a lubrication system?

The OS-MV-2218-30 is engineered to work in tandem with Sommer-Technik OS-BP lubrication pumps. When the pump is at rest, the secondary oil circuit remains pressure-free — the normally closed valve isolates it from the main lubrication line. When the PLC or machine controller energises the 24 V DC coil, the valve opens and admits oil from the second circuit. This architecture allows machines with a single pump to selectively engage a supplementary lubrication point — such as a spindle bearing or a slideway — without adding a dedicated pump. The DIN 43650 electrical connector simplifies integration into standard machine control panels.

What are the electrical and environmental operating limits?

The coil draws 8 W (11 VA) at a nominal 24 V DC, with a voltage tolerance of −15% to +10% and a 100% duty cycle rating for continuous operation. The 360° stepless coil rotation allows the electrical connection to be oriented to fit tight mounting spaces. IP54 ingress protection with an appropriately fitted DIN plug guards against dust ingress and splashing water, while the 50°C maximum ambient temperature supports installation in warm machine enclosures. Threaded ports accept standard oil line fittings for straightforward plumbing into existing lubrication circuits.
