Argo Hytos Check Valves

Argo Hytos check valves are designed to enable flow of the fluid in one direction only.

They protect hydraulic components from a backflow of fluid caused by the load on the appliance; in the reverse direction, the working fluid pressure acts on the hardened cone or ball towards the valve sealing edge. The resting position of the cone or ball is enforced by a spring of low stiffness. The check valves fitted with a stronger spring are sometimes used as back pressure valves creating a slight overpressure, or simple pressure relief valves.

Control of the check valve secures the position of a load when the pressure source is switched off. Logic valves connect circuit branches depending on the pressure range.

The full range of these Argo Hytos valves is as follows:

• Logical 3 way check valves: SH1F-A3 series

• Check valves with one-way throttling: VJS3 model
