Operation

N/A The DB16P blocks flow from port 1 to port 2 until the pressure setting is reached at port 1 to lift the pilot poppet, creating a pressure drop across the main spool. This allows the main spool to shift, opening port 1 to port 2. Pressure at port 2 is directly additive to valve pressure setting.
