The 1PSC30-F-10S-A5B valve is produced by Vickers for the Sequence and Unloading Valves series and is intended to manage staged pressure events in hydraulic automation circuits. The unit is supplied as a screw-in cartridge so it can be inserted directly into a manifold block, and a thread size of M20 × 1.5-6g defines the male mounting interface. The body hex measures 25.4 mm across flats, allowing a standard wrench to secure the valve, and correct seating is achieved by tightening to 45 Nm during installation. The cavity required is designated A6610, matching common Vickers manifold patterns. This model operates in direct-acting mode for rapid response without a pilot stage. Three ports are provided to separate inlet, outlet, and bypass functions, and there is a reverse flow check to permit free return when pressure falls. The assembly weighs 0.15 kg, which minimizes manifold mass.
The factory set pressure is 135 bar, so the valve begins sequencing at that threshold, while a rated pressure of 350 bar allows it to withstand higher system loads. During normal operation it passes up to 30 l/min, and adjustment can be performed at a setting flow rate of 4.8 l/min to fine-tune the opening point. Internal leakage is limited to 0.3 ml/min, maintaining circuit efficiency even when the valve is closed. Reliable service is maintained from –30 °C to +90 °C, covering typical mobile and industrial temperature ranges. These performance figures enable the valve to control sequential functions, modulate unloading, and protect downstream components without sacrificing flow capacity.
