Pressure Relief Valve DBW 20 B2-5X/200-6EG24N9DK24L2/12 - Bosch Rexroth R978910411

A relief valve has to hold its setting even while the pump delivers full flow. This pilot-operated seat valve in size 25 covers a setting range of 4 to 200 bar, passes up to 500 l/min and is rated for a maximum operating pressure of 350 bar.

Benefits

• Setting range of 4 to 200 bar, adjusted through an internal hexagon behind a protective cap
• Flow up to 500 l/min through a subplate interface to ISO 6264-08-13
• Pilot-operated seat design rated for a maximum operating pressure of 350 bar
• Solenoid actuation at 24 VDC, two switching positions for pressure limitation and unloading
• Electrical connection 3-pole (2 + PE) to EN 175301-803, plug-in connector M12 x 1 with A coding

Application

The valve sits on the pressure side of stationary power units, presses and test rigs that need a fixed pressure ceiling plus a switchable bypass. NBR seals suit HL mineral oil. At 5.3 kg it stays a one-person job to mount on the subplate.
