Eaton leads the industry in screw-in cartridge valve (SiCV) technology with a wide selection of hydraulic valves for both stationary and mobile equipment. This product line includes pressure, flow, proportional and logic element screw-in cartridge valves and hydraulic integrated circuits.

This valve provides a means of sensing the higher pressures between two lines on a  hydraulic circuit allowing this line to be used for an auxiliary function such as the removal  of a mechanically applied brake, the operation of a gauge or to give a remote pressure  sensing line for the control of a separate valve.

Operation
When a higher pressure is sensed at inlet 1 than at inlet 2 the ball within the cartridge is forced against a seat opening the higher pressure to outlet.
When the higher pressure appears at inlet 2 the ball is forced against the other seat which blocks inlet 1 and opens up inlet 2 to outlet.
Features
Cartridge design enabling speedy servicing when mounted in a body or in a composite manifold.
