Pressure Relief Valve DBW20B2-5X/100-6EG24N9K4/12=CSA - Bosch Rexroth R901227554

A test pressure only means something when it is applied identically to every component. The pilot-operated DBW20B2-5X/100-6EG24N9K4/12=CSA works inside the narrow 4 to 100 bar window for that and is trimmed finely at the internal hexagon.

Benefits

• Adjustment range 4 to 100 bar, the whole travel lies inside the test pressure window.
• 500 l/min in size 25, enough for short pressure build-up times.
• Symbol B with two switching positions, commanded electrically on 24 VDC.
• 350 bar permitted operating pressure, the valve stays loadable after an operating error.
• 5.28 kg, subplate mounting ISO 6264-08-13, NBR seals.

Applications

The valve is used in test rigs, leak testing plant and clamping fixtures with a limited working pressure. Its low adjustment range keeps sensitive test pieces from being overloaded. The second switching position lets the test circuit be relieved from the control system.
