Description

DESCRIPTION The PRE3G, PRE3GL, and PRE3GH are proportional pilot operated pressure reliefl valves, for subplate mounting. They controls the pressure in hydraulic circuits. On-Board Electronics Options for open loop: G Version: Standard electronics with an analogue interface, with current or voltage reference signal, and a 6-pin + PE connection. Ideal for traditional applications with direct control. GL Version: Compact and cost-effective electronics with Io-Link, Can-Open, or analog interface and a 5-pin M12 connection. Perfect for applications requiring advanced connectivity. GH Version: Supports fieldbus communication with EtherCAT, Ethernet/IP, and Profinet interfaces, using an 11-pin M12 connection. Optimal for advanced industrial applications with complex communication needs.

Key Features

• Closed-loop control with integrated electronics • Higher flow and broader pressure ranges • Precise regulation and high repeatability • IP67 rated for harsh environments • Ideal for complex hydraulic circuits
