Description

DESCRIPTION The PDE3 is a proportional pressure relief valve, direct operated, for subplate mounting. It is suitable to pilot two-stage valves, or for pressure control in hydraulic circuits. This valve has a mechanical pressure limitation feature, for higher safety of the application. It is available in five pressure regulation ranges up to 350 bar and it can be controlled directly by a current-controlled power supply, or by an electronic card, to be order separately.

Key Features

• Subplate mounted ISO 4401-03 interface • Wide pressure control ranges up to 350 bar • Excellent stability and repeatability • Available in 12 or 24 V DC versions • Compact footprint for easy integration
