Pressure limiting valve with replacement control valve

Pressure limiting valve with control and valve pistons which move separately against respective valve and regulating springs, whereby the valve piston moves to expose discharge openings, after the control piston having a blind hole larger than a through-bore located in the valve piston moves enabling the valve piston with a significantly larger diameter to open against a pressure of the regulating spring and of a pressure medium present in a compensation chamber, characterized in that

• the control piston (24) and the valve piston (6) are coordinated with separate valve cases (22, 10) which are connected with each other by way of a plug-in fitting (35) which can be screwed into the valve case (10) of the valve piston (6) and has on the opposite side (37) a standardized plug connection (38) and a center bore (40), and that the blind hole in the valve piston (6) is connected by way of a through-bore (11) to the compensation chamber (13) on the opposite side of the valve piston, whereby the diameter of this through-bore is smaller than that of the blind hole (26) of the control piston (24).
