VICKERS-1SER140F30S4-SP4100

Harvesters are actually one of the named applications for this valve, so you're in the right ballpark. It handles a rated flow of 140 litres per minute and holds up to 350 bar (5,000 psi) system pressure, which gives it solid credentials for keeping moving loads stable. The pilot-assisted relief with check design is specifically what helps prevent that load drift you're describing, since it's built around maintaining pressure integrity while managing dynamic loads. As long as your system operates within those pressure and flow parameters, this is a well-matched option for that use case.

This valve is well-suited to refuse haulers and other heavy mobile equipment due to its pilot-assisted relief with check. It is designed to provide stable load handling.
