General

2-way cartridge valves for pressure functions are pilot-operated valves in seat or spool design. The power section designed as cartridge valve (1) is installed into a receiving hole standardized according to DIN ISO 7368 and closed with a control cover (2).

The pilot control valve (4) for manual or electrically proportional pressure adjustment is integrated into the control cover (2) or is installed on the control cover (2) as pilot valve with mounting dimensions according to DIN 24 340.

By combination of cartridge valves with the control covers, different pressure functions can be realized. .

Pressure relief function

The cartridge valve (1) for the pressure relief function (type LC . DB...) is designed as seat valve without area difference (no effective area at port B). The effective pressure at port A is directed via the pilot oil supply orifice (5) to the spring side (6) of the element. Under the pressure set at the pilot control valve (4), the spool (3) is pressure-compensated and closed by the spring force.

On reaching the set pressure, the spool (3) is opened and the pressure at port A is limited according to the pressure-flow characteristics.

Pressure reducing function

Rest position open

The cartridge valve for the pressure reducing function is designed as spool valve without area difference (no effective areas at port B).

As pilot control valve, identical cover types as for the pressure relief function are applied (type LFA..DB...).

The effective pressure at port A is directed via the pilot oil supply orifice to the spring side of the spool. Under the performance limit and the pressure set at the pilot control valve, the spool is pressure-compensated and retained in open position by the spring force to enable free flow from port B to port A.

On reaching the set pressure, the spool is closed and the pressure at port A is reduced according to the pressure-flow characteristics.

Notice:

By combination of a 2-way cartridge valve with a pilot control valve, various valve functions can be realized.

In particular, the following devices come into question in porting pattern form A6 (up to NG 63) and form A10 (NG 80 to 100) DIN 24 340.

Valve mounting screws are included in the scope of delivery of the control cover.

Orifice symbol	Symbol in ordering code
A**	A**	This orifice is designed as screw-type orifice. If an orifice is to be installed, the respective code letter with the orifice Ø in 1/10 mm has to be entered in the type designation. Example: A12 = Orifice with Ø1.2 mm in channel A.
Ø1,2		This orifice is designed as bore. No specifications are made in the type designation. (Orifice Ø in mm)
Z12		This orifice is designed as screw-type orifice. This is a standard orifice. No specifications are made in the type designation. (Orifice Ø in 1/10 mm)

Additional preferred types and standard units are specified in the EPS (standard price list).
