The 180L0128 valve belongs to the VDHT Solenoid Valves series manufactured by Danfoss for hydraulic automation where electrically triggered flow control is needed. It is a 2/2 device that directs fluid between two ports, and the pilot-operated design lets a small coil shift a larger main poppet for efficient actuation. An AISI 304 stainless-steel body resists corrosion in oil circuits, while an FKM seal maintains tight shut-off with typical hydraulic media. The valve contains an 18.1 mm piston that sets the flow passage and response forces. Process connections follow the NPT thread form, and both the inlet and outlet measure 1/2 in to match standard pipework. Maximum opening time is 125 ms, allowing rapid service-line pressurization.
The unit passes up to 60 l/min, supporting medium-capacity actuator groups without excessive throttling. It is rated for continuous service at 210 barg and requires at least 4 barg to keep the pilot circuit functional. Fluid temperatures may range from 2 °C to 90 °C, so the assembly can handle chilled or moderately hot oil streams. When the coil is de-energized, the valve closes in no more than 300 ms, limiting reverse flow or pressure spikes. These time, pressure, temperature, and flow limits define installation envelopes and help designers match the valve to pump output, reservoir condition, and cycle requirements.
