The 180L1033 lock solenoid valve belongs to the VDHT Solenoid Valves series and is manufactured by Danfoss for hydraulic automation tasks. It uses pilot-operated actuation so the poppet can shift with only 1 l/min of pilot flow. A 2/2-way configuration provides simple open-and-close control of the main line, while the poppet seat keeps the passage sealed when the coil is de-energized. Nominal flow is rated at 30 US gpm to handle medium-capacity circuits. The body is made from stainless steel AISI 304 for corrosion resistance, and NPT 1-3/4 threads allow direct connection to standard pipework. These features work with the specified lock function to secure hydraulic positions when required.
The valve withstands pressures up to 2000 psi and works with media from 2 °C to 90 °C, covering typical hydraulic temperature ranges. It accepts viscosities up to 45 mm²/s, so common oils remain inside the operating window. A strainer no larger than 200 µm protects internal parts, including the piston made from stainless steel AISI 316. The assembly weighs 5.9 kg, a factor to consider when mounting it in manifolds or line runs. Together, these limits define the operating envelope and help maintain reliable sealing and actuation performance across the stated pressure range.
