Pressure Relief Valve DBW20B2-5X/160-6EG24N9K4VE - Bosch Rexroth R901185379

The pressure stage of a valve should match the circuit, otherwise the setting sits against the end of the spring travel. This version is rated for 4 to 160 bar and accepts up to 400 l/min in size 25.

Benefits

• Pressure stage 4 to 160 bar for circuits below the high-pressure class, maximum operating pressure 350 bar.
• Flow up to 400 l/min, subplate mounting to ISO 6264-08-13.
• Pilot-operated seat valve with 2 ports and 2 switching positions.
• FKM seals, HL hydraulic fluid, 24 VDC supply voltage.
• 5.36 kg weight, spool symbol B, 3-pole connector (2 + PE) to EN 175301-803.

Application

Typical installations are presses, clamping systems and power units whose system pressure sits around 100 to 150 bar. In that band the pressure can be set more finely than with a spring rated for 315 bar. The internal hexagon with protective cap secures the setting.
