Closing cartridge valve
The 2/2-way cartridge valve is a 2/2-way valve. It is fitted with two working ports and the two switch positions closed
and open
. Whether or not the cartridge valve is open or closed depends on the effective areas A and X, the adjacent pressures pA, and pX, as well as the spring force. A=X is valid.
If pA*A > pX*X + F, then the valve closes, otherwise it is open.
The valve therefore operates purely pressure dependent and can, with the appropriate control, assume directional-, flow- and pressure functions. The spring force is specified by means of the nominal pressure. This is the minimum pressure, with pressureless connections at B and X, necessary at connection A to open the valve.
The hydraulic resistance relates to the completely opened valve.
