Pressure Relief Valve DBGT-1X/100P2-673 - Bosch Rexroth R900557243

A power unit whose pressure is reset several times per cycle needs a valve that follows the command signal and stays tight at rest. The DBGT-1X/100P2-673 is pilot-operated and built as a poppet valve. It limits within the 100 bar pressure rating, allows 315 bar operating pressure and passes up to 600 l/min.

Benefits

• Maximum flow of 600 l/min takes the delivery of larger pumps without a pressure peak.
• Operating pressure up to 315 bar covers the range of common industrial power units.
• Poppet design keeps leakage low in the limited state, unlike a spool solution.
• Electrical adjustment at 24 V DC through external electronics replaces manual resetting.
• Subplate mounting with 2 ports and 2 switching positions, spool symbol A to B, X to Y.
• NBR seals for HL hydraulic fluid, weight 5.4 kg.

Applications

The valve works in press power units, in clamping circuits and on test benches where pressure is switched every cycle. Since the external electronics supply the command value, the pressure can be changed from the machine control. For plants running HL mineral oil the NBR sealing is the matching version.
