180G0040

The 180G0040 valve is part of the VPH Power Pack Valves series from Danfoss and is intended to direct hydraulic fluid in compact power units used for mobile and industrial automation. It is configured for a steady flow rating of 15 l/min so pump selection can match continuous circuit demand without cavitation or excess heating. The inlet is set at 3/8 in to interface with standard hose fittings on small displacement pumps. A minimum operating pressure of 25 barg ensures that internal passages stay fully pressurized to maintain predictable metering through the orifice. The valve tolerates media temperatures down to −30 °C, allowing cold-start operation in outdoor machinery.

Under peak load the 180G0040 accommodates a maximum flow of 20 l/min, which provides headroom for transient spikes when actuators shift abruptly. The assembly supports a maximum operating pressure of 140 barg so cylinders and motors can generate high force without valve distortion. The outlet is also sized at 3/8 in, enabling balanced line connections that minimize restriction on the return side. Fluid temperatures may rise to 50 °C during sustained duty, and the valve materials are selected to retain sealing integrity at that limit. These parameters position the unit as a stable control element in hydraulic circuits that require compact packaging and reliable pressure handling.
