Description

DESCRIPTION The PLKE08 is a direct operated proportional pressure relief valve, cartridge version, to be installed in blocks and manifolds with SAE-08 seat . The valve is suitable as a pilot stage for remote control of two-stage pressure control and pressure reducing valves. The valve is available in four pressure regulation ranges up to 350 bar. It can be controlled directly by a current-controlled power supply, or by an electronic card, to be order separately. This valve replaced the discontinued CRE valve.

Key Features

• Direct operated cartridge valve • High-pressure control up to 400 bar • Low nominal and maximum flow rates • Excellent hysteresis and repeatability • Compact design for space-saving installations
