The 100 l/min relief valve is a very reliable, pilot operated cartridge valve, with excellent repeatability. Available as a cartridge to fit a standard Hy-Pro cavity or in a range of single and twin cartridge manifolds. The twin cartridge, 4 ported manifold is commonly used to prevent shock loads in hydraulic motors and equal ended cylinders.
The adjustable relief valve cartridge is a pilot operated relief valve with extremely flat flow/pressure characteristics to ensure that the setting accuracy is maintained over a wide band of flow. It can be supplied as a cartridge in a manifold for inline relief and two together in a manifold for dual line relief. Adjustments are made using the Grub screw and lock nut, which can be fitted with an optional tamper evident cap.
