Eaton Check Valves DT8PI/C2-8*/C5G-8


The directly operated, angled, gasket mounted and inline check valves described in this leaflet are used in hydraulic systems where check valves, which are closed by a limited spring force, are required allowing oil flow in one direction only.

Various cracking pressures are available depending on the rating of the spring used. All models, except the inline check valves, can be used for a variety of flow conditions including high velocity flows resulting in shock conditions. Inline models are intended for low shock service.

An option on the C5G and C2 valves allows for a hole to be drilled in the poppet to provide a small return flow when the valve is closed.

Contamination Control Requirements

Recommendations on contamination control methods and the selection of products to control fluid condition are included in Vickers publication 9132 or 561, “Vickers Guide to Systemic Contamination Control”. The book also includes information on the Vickers concept of “ProActive Maintenance”.

The following recommendations are based on ISO cleanliness levels at 2 m, 5 m and 15 m. For products in this catalog the recommended levels are:

Up to 210 bar (3000 psi) 20/ . . . . . 18/15
Above 210 bar (3000 psi) 20/ . . . . 18/15
