Pressure Relief Valve DBW30B2-5X/315YU6EG12N9K4/12 - Bosch Rexroth R978917498

Technical data

Application

Clamping and holding circuits often stay pressurised for hours while the pump is off. A poppet seat in the main stage shuts tight and holds the value. The 12 V coil suits controls without their own 24 V level.
