Operation

N/A The DB08P blocks flow from port 1 to port 2 until the predetermined pressure setting is reached at port 1 to lift the spring opposed pilot poppet off its seat, creating a low flow and a pressure drop across the orifice in 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
