Hydraulic Check Valve
Stucchi provides superior hydraulic check valves, proven to prevent potential damage from fluid back pressure. Their check valves are ideal in any type of hydraulic circuit, providing safety in a compact design suitable for any hydraulic application with non-corrosive liquids. Check valves can also be adjusted to use as pressure sequence valves.

Their hydraulic check valve product options include:
• VU
• VUX
• VUZ

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.
