Designed for mobile and industrial applications including harvesters and refuse haulers, the Vickers 1SEL30F40S300/50 Overcenter Valve is a pilot-assisted relief valve with integrated check, engineered to provide stable load control under demanding duty cycles. Its overcenter design allows controlled movement of suspended or overrunning loads, making it well suited for hydraulic circuits where load-induced motion must be managed precisely.
Rated to 350 bar (5,000 psi) and capable of handling flows up to 550 L/min (143 USgpm), this valve carries a nominal flow rating of 30 litres per minute and meets the ISO 8643 standard for motion control valves. Manufactured under the Vickers brand by Danfoss/Eaton, it belongs to the 1SEL30 series of SICV motion control valves known for consistent stability when managing moving loads across mobile and stationary hydraulic systems.

Question by: Brent W on Nov 1, 2025, 5:27 PM
runs up to 550 liters a minute but what's the nominal flow this thing's actually rated for day to day?
Answer by: Customer Support on Nov 2, 2025, 9:50 PM
Nominal flow on this valve is 30 litres per minute. The 550 L/min figure is the maximum it can handle, but for steady, reliable operation in a working circuit, 30 LPM is the number you want to plan around. It's built for mobile and industrial duty cycles, so that nominal rating reflects real-world conditions like what you'd see on a harvester or refuse hauler running regular shifts.
