Maximum Cartridge valves are basically composed of a cover and an operating unit insert in the ISO 7368 (DIN 24342) mounting frame. Each cartridge valve is characterized by 2 main way for the nominal flow (up to 350 l/min).

Maximum pressure cartridge valves allow control of hydraulic circuit pressures up 400 bar and 350 l/min maximum flow rate (NG25). Besides the normal manual pressure regulation mode, function like electrical command for discharge to drain, remote control, proportional pressure control or electrically selected dual pressure levels are also available.

KRA – Cartridge valves with electrical position control This valve serie is used in those applications where monitoring of the “actual” valve position is required for managing machine safety cycles as required by current accident prevention legislation.

The valve has a combined function in a single cartridge. It consists of a direct acting maximum pressure valve and a unidirectional check valve.
