Got a harvester that needs a motion control valve and I keep seeing this part number come up, does the 1SER30F35S4 actually hold up in that kind of application?
Answer by: Customer Support on Aug 23, 2025, 4:21 PM
Harvesters are one of the listed applications for this valve, so you're on solid ground there. The 1SER30F35S4 is part of the Vickers 1SER30 Series of SICV Motion Control Valves, and it's built around a pilot-assisted relief with check configuration, which is well-suited for managing moving loads in field equipment like that. It carries a 30 litre per minute nominal flow rate and is rated to 350 bar (5000 psi), with a max flow capacity of 550 L/min. It also meets ISO 8643, which is the relevant standard for this class of motion control valve.
