Can this handle the hydraulic demands of a combine harvester or a big ol' garbage truck, or is it meant for lighter duty stuff?
Answer by: Customer Support on Jun 29, 2025, 1:15 PM
This Vickers check valve is specced for mobile and industrial applications like harvesters and refuse haulers, so it should be right at home in those demanding environments.

Running a refuse hauler and need a check valve that won't give out under steady pressure. This one rated for that kind of work?
Answer by: Customer Support on Sep 18, 2025, 7:58 AM
Refuse haulers are actually one of the listed applications for this valve, so it's built with that environment in mind. It handles up to 350 bar (5000 psi) and flows up to 120 liters per minute, which covers the demands that come with that type of equipment. The low spring settings also help keep things running efficiently without fighting back pressure more than necessary.
