Check valves for extreme requirements up to 10,000 bar / 150,000 psi
Thanks to large nominal bores, they enable high flow rates with minimal pressure loss. Installation is particularly user-friendly: The integrated double-threaded screw with both right- and left-hand threads allows for quick, stress-free assembly – without twisting the tubing.
Whether in test benches, waterjet systems, or isostatic presses – WEH® check valves stand for long-lasting quality and well-engineered design. Custom versions are also available for specific media and application requirements.
High Flow with Low Pressure Drop
The generously dimensioned nominal bore ensures optimal flow – ideal for dynamic high-pressure processes.
Quick & Stress-Free Installation
The integrated double-threaded compression screw simplifies installation, prevents tube twisting, and saves assembly time.
Durable Sealing Technology
Sealing is achieved via a high-quality ceramic ball – low-wear, reliable, and designed for long service life.
Pre-Assembled & Ready to Install
Delivered with pre-assembled ferrules and compression screws – for immediate and secure installation into the system.
