VU SERIES

The VU series check valves are used in any type of hydraulic circuit, with a safe, compact design suitable to any hydraulic application using non-corrosive liquids. The VU size range includes two different standard openings at 5 to 65 psi. The VU series can also be used as a pressure sequence valve by adjusting the internal spring loading to the required cracking point, according to the valve size.
