Description & Features

Designed for demanding mobile and industrial environments, the Vickers 4CKKT503S3-35 is a poppet-style check valve rated to 350 bar (5,000 psi) with a flow capacity of 25 litres per minute. Its low spring settings support high operational efficiency across a range of circuit conditions, making it well suited to applications where consistent, reliable flow control is a priority.

Typical deployment includes harvesters, refuse haulers, and broader mobile hydraulic systems, as well as fixed industrial installations. As part of the Vickers 4CKKT series, manufactured under the Danfoss/Eaton umbrella, this valve benefits from proven SICV check valve engineering, balancing compact construction with robust pressure handling capability.

Got a harvester that keeps giving me grief with flow control, would this Vickers check valve hold up in that kind of application?

Answer by: Customer Support on Aug 14, 2025, 9:04 PM

Harvesters are actually one of the listed applications for this valve, so you're in the right territory. It's a poppet-style check valve rated to 350 bar (5,000 psi) with a flow capacity of 25 litres per minute. The low spring settings are part of what makes it well suited to mobile equipment where consistent flow control matters. It comes from the Vickers 4CKKT series under the Danfoss/Eaton umbrella, built on SICV check valve engineering, so it's got solid lineage for demanding field conditions.

Reckon this check valve would hold up okay on a refuse truck?

Answer by: Customer Support on Jul 3, 2025, 6:19 AM

Application-wise, yes, this poppet-style check valve is indeed suited for refuse haulers, along with harvesters and other mobile hydraulic systems. It's also good for fixed industrial setups.
