HYDAC offers a wide range of direct acting and pilot operated Relief and Reducing Valves. In general, the direct acting valves are faster in response while pilot operated valves have flatter pressure/flow characteristics.

HYDAC Relief Valves are available in direct acting poppet and pilot operated spool types with optional pressure adjustment ranges up to 6000 psi (420 bar). Models are available for flow rates up to 80 gpm (300 l/min).

Operation

N/A The DB08A blocks flow from port 1 to port 2 until the pressure setting is reached at port 1 to lift the spring opposed poppet from its seat, allowing flow from port 1 to port 2. Pressure at port 2 is directly additive to valve pressure setting. Flow from port 2 to port 1 is checked.
