Prevent Fluid Leak with Hydraulic Check Valves

Hydraulic check valves are critical to prevent leaks and damage from fluid back pressure, protecting hydraulic circuits from contamination.  Check valves also improve the safety of hydraulic connections and may be adjusted for use as pressure sequence valves. Stucchi offers a wide product selection including check valves suitable for use in any type of hydraulic circuit.

Stucchi Offers Hydraulic Check Valves

Stucchi is a leading global supplier of hydraulic quick couplers, check valves and accessories, offering custom designed quick connect solutions that meet your specific requirements.  Our check valves are proven in a myriad of industries worldwide, and include the following product options:

VU / VUZ SERIES - The VU check valve series provides a compact design, safe for any hydraulic process with non-corrosive liquids.  Sizes range from two standard openings at 5 – 65 psi.  The internal spring loading may be adjusted to the cracking point to be utilized as a pressure sequence valve. The VU series is ideal in the oil and gas industry, mobile and agricultural equipment.

VUX SERIES – similar to the VU series, the VUX offers a compact design suitable for non-corrosive hydraulic applications. The size range is a standard opening at 7.5 psi, with the ability to adjust the internal spring loading to the desired cracking point for use as a pressure sequence valve.  The VUX is ideal in oil and gas, mobile and industrial equipment applications.

VUZ Series – Similar to the VU the VUZ series is compact and safe for non-corrosive hydraulic applications.  Sizes are available at two standard openings of 5 – 65 psi.  Adjusting the internal spring loading to the desired cracking point allows for use as a pressure sequence valve.  The VUZ check valve series is ideal in the oil and gas industry, agricultural, mobile and industrial equipment hydraulic quick connect processes.

Our check valves are available in various materials including black phosphate or steel with zinc plating optional, AISI 316 or 360 stainless steel or high strength carbon steel.
