The PSV8-10-S-0-24 valve belongs to the Sequence and Unloading Valves series manufactured by Vickers and is intended to manage sequencing or unloading tasks in hydraulic automation circuits. It is a normally closed spool design that blocks flow until a hydraulic pilot signal shifts the spool to the open position. Technicians set the opening point through an external adjustment screw, allowing calibration without dismantling the assembly. The unit installs as a screw-in cartridge and matches a 7/8-14 threaded port while occupying an SDC10-3 cavity, so it fits common manifold layouts. Its regulated opening can be configured anywhere from 25 to 165 bar, giving flexibility for a wide range of system pressures.
An internal drain routes pilot oil back through the outlet passage, eliminating the need for a separate drain line. The cartridge is supplied without a housing, which encourages direct integration into custom blocks to save envelope space. Overall length measures 5.780 in (146.812 mm), and both width and height are 1.000 in (25.400 mm), allowing dense stacking of multiple valves in compact manifolds. Correct installation torque is 47–54 Nm, providing a secure seal without overstressing the mounting threads.
