Short descriptionFor ultra-high pressure up to 4,200 bar / 60,000 psi
Product descriptionWhere the medium in a pipeline must flow in only one direction and backflow must be prevented, the WEH® ultra-high pressure check valves perform this function reliably. The large effective nominal bore ensures high flow rates with low pressure drop. Installation is simplified by the integrated double-pressure screw: the check valve is tightened on a single wrench flat, avoiding stress or rotation of the tube.
Features- Easy installation thanks to integrated double-pressure screws with 1 left-hand and 1 right-hand thread
- High flow capacity due to large effective nominal bore
- Long service life thanks to sealing with a high-grade ceramic ball
- Supplied with preassembled pressure rings and pressure screws
ApplicationThe WEH® ultra-high pressure check valves with ball sealing are specifically designed for hydraulic applications in the high-pressure range. Alternative designs for other media and applications are available.
